Tales to Astonish I#94/2 (fb) - BTS) - At some point while dwelling in his Citadel of Science atop Mount Wundagore, the High Evolutionary used his genetic accelerator to evolve a leopard into one of his New Men.

(Thor I#135 (fb) - BTS) - Wyndham taught his New Men language, science, biology, and history.sir_lepard-kow-xma12-knighted

(Thor I#135 (fb) / Tales to Astonish I#94/2 (fb) - BTS / X-Men I Annual#12/3) <Circa 1958> - Like most of his New Men at the time, the High Evolutionary had his ally Jonathan Drew (possessed by the Arthurian-era sorcerer Magnus) train the leopard man in the ways of the knights of old, striving to teach him a code of honor and chivalry; he dubbed him Sir Lepard and pronounced him and his associates as Knights of the Realm (later known as the Knights of Wundagore).

(X-Men I Annual#12/3) - These six newest Knights, which also included Sir Gote, Sir Hogg, Sir Lyan, Sir Ossilot (and one not pictured/identified), brought the number of knights up to forty-two.




(X-Men I Annual#12/3) - Soon after, the Knights were called forth to battle the Other, the elemental host of the demonic Elder God Chthon, summoned by the Chthon-pawn Gregor Russoff via Chthon's tome, the Darkhold. While they fought valiantly, the battle was only won when Magnus possessed Russoff and recited the spell of binding, trapping Chthon within Mount Wundagore.

    Over half of the Knights of Wundagore perished in that battle.


sir_lepard-kop-thor134-vs. Thor

(Thor I#132-134 - BTS) - In recent years, Count Tagar and Sir Porga brought Jane Foster to the High Evolutionary's citadel to educate the New Men in the ways of the outside world.

(Thor I#134) - As Thor arrived approached Mount Wundagore, investigating Jane Foster's disappearance via a Rigellian tracking device, the Knights of Wundagore -- including Sir Lepard, Sir Lyan, and Sir Ossilot -- detected and approached him via their atomic steeds, after which they lassoed him. 

    Certain they would bring him to Jane, Thor allowed them to bring him into the High Evolutionary's Citadel, after which he tossed the Knights around when they refused to release him. One of the other knights specifically noted Thor was spinning Sir Lepard about as if he were but a toy (two knights were shown being spun).

    The Knights soon agreed to stop fighting and discuss matters, and -- at Thor's request -- one of them removed his helmet, revealing his true nature. When Thor forced his way in to confront the High Evolutionary, the distraction caused the Evolutionary's wolf-subject to be over-exposed to Isotope C.

    After the energies around the wolf caused an explosion, the High Evolutionary noted how the wolf would be evolved farther than he had ever dared to go before. Sir Ossilot asked if the Evolutionary could not halt the machine, but the Evolutionary noted that the rays were now deadly to him and that it was too late. 

(Thor I#134 - BTS) - Rendered both mad/malevolent and uncontrollably powerful, the wolf (identified as the Man-Beast) plotted to destroy those around him. 



sir_lepard-kop-thor135-charge-lateral(Thor I#135) - After the Man-Beast attacked Thor, the High Evolutionary told his Knights -- including Sir Lepard -- to stand back as he attempted to destroy the Man-Beast with his sub-sonic discordion. Only pained, the Man-Beast fled out of range and locked himself within the Evolutionary's genetic laboratory, which contained his evolutionary ray.

(Thor I#135 - BTS) - As at least one Knight, possibly Sir Ossilot, watched, the Evolutionary throw some object against the wall to demonstrate that the Man-Beast had created an anti-matter barrier to prevent them from breaching his vault. By the time the Evolutionary used his induction device to force the Man-Beast to confront them, the Man-Beast had already created a number of his own New Men, who then engaged Thor and the Evolutionary. 

(Thor I#135) - Donning his cathode gloves, Count Tagar led the Knights of Wundagore to engage the New Men. After Thor subdued the Man-Beast, the Knights forced the rest of the New Men into the Evolutionary's Star Chamber, which then transported them to the "galaxy Dromisana."


(Thor I#135 - BTS) - Deciding that they would continue to endanger mankind if they remained on Wundagore, the High Evolutionary instructed Thor and Jane Foster to depart. With his citadel in the form of a starship, the Evolutionary piloted it to depart Earth. 

sir_lepard-kop-awcan3-flight(West Coast Avengers Annual#3/3 (fb)) - Sir Lepard was one of 38 Knights of Wundagore aboard the Evolutionary's Citadel-turned-ship. Eventually -- after traveling through hyperspace --the Evolutionary's ship...

(West Coast Avengers Annual#3/3 (fb) / Tales to Astonish I#94/2 (fb) - BTS) - ...emerged near an apparently hospitable star system, and they landed on a near-Earth-like planet.

(West Coast Avengers Annual#3/3 (fb) - BTS) - The Evolutionary sent forth his Knights to explore this planet, and they discovered and reported an abandoned city.

(West Coast Avengers Annual#3/3 (fb)) - One of the Knights (presumably Count Tagar), officially claimed the world in the name of the High Evolutionary.

(Tales to Astonish I#95/2 (fb) - BTS) - They named the world Wundagore II...

(Tales to Astonish I#94/2 (fb) - BTS / West Coast Avengers Annual#3/3 (fb) - BTS) - ...and they (re)built the city, adapting it to their use.

(Iron Man I#111 (fb) - BTS) - The Evolutionary and his Knights encountered the giant praying mantis-like creatures apparently native to this world.. 

    As these creatures made no use of the world's riches, the High Evolutionary banished them to the swamps.

(West Coast Avengers Annual#3/3 (fb)) - Meanwhile, the High Evolutionary used the menagerie of animals contained in his citadel to evolve a female of each species he had already evolved for his knights.

(West Coast Avengers Annual#3/3 (fb)) - The High Evolutionary presented the women to his knights to become their wives. 

    The Evolutionary told the couples to go forth into the new city and to be fruitful and multiply; he further advised them that he had exhausted his stores and that from then on, they would be responsible for replenishing their numbers.

(Tales to Astonish I#94/2 (fb) - BTS) - Their little civilization thrived and flourished in peace and prosperity initially. 

(West Coast Avengers Annual#3/3 (fb) - BTS) - The High Evolutionary left his charges to their own pursuits as he remained in his laboratory and devoted himself to his research.

(Tales to Astonish I#94/2 (fb)) - The New Men began reverting back to their bestial heritage, and they savagely attacked each other. 

(West Coast Avengers Annual#3/3 (fb) - BTS) - The Evolutionary tried to reason with his rampant subjects to no avail, and he searched Wundagore II for new specimens to evolve in hopes of creating beings capable of restoring order, but there were none to be found. 

(Tales to Astonish I#94/2 (fb) - BTS) - Eventually the High Evolutionary had the Hulk transported to Wundagore II. 

(Tales to Astonish I#96/2) - The maddened New Men / Knights of Wundagore then broke into the High Evolutionary's base. 

    High Evolutionary assaulted the maddened Knights, but he was mortally wounded and then subjected himself to his Genetic Accelerator.

     After the Hulk had pummeled all of the Knights unconscious, the Evolutionary, now a being of psionic energy, devolved all of his Knights/New Men back into purely animal form.and sent the Hulk back to Earth before "becoming one with the cosmos."sir_lepard-kow-im111-vsimsir_lepard-kow-im1110-spacesuit

(Iron Man I#111 (fb) - BTS) - The Rigellians serving the rogue Arcturus believed themselves to have found a new home when one of their space probes discovered Wundagore II. 

     The Rigellians found traces of a once-thriving civilization, but they saw only wild beasts foraging in it cities. The Rigellians were overjoyed, and they considered that this world would be New Rigel.

    When the Rigellians' exploratory craft landed, the wild beast fled, but cosmic radiation born by the ship from its journeys through space somehow caused the beasts to re-evolve back into the forms of the New Men, bereft of the savagery that had previously afflicted them.

    Speaking and clothing themselves, the New Men returned to their cities to see if they could recall what had caused them to devolve. 

    Whether they learned what had happened to them, they recalled that they were the Knights of Wundagore and that they had returned to their home. 

(Iron Man I#111 (fb) - BTS) - Although there was plenty of room on the planet for them all, the Rigellians were unwilling to live with beasts, and the Knights of Wundagore were willing to fight to keep their world and drive off the invaders.

(Iron Man I#111 (fb) - BTS) - Prior to any actual war being declared, the Rigellians allegedly attacked and wounded a number of the New Men. The Rigellians also allegedly tortured some of the New Men for information.

(Iron Man I#109 - BTS / Iron Man I#110 (fb) - BTS) - Earth heroes Iron Man and Jack of Hearts were transported to Arcturus' ship, and Arcturus noted that they were preparing for the final battle in the war of colonization with the resisting inhabitants of Wundagore II.sir_lepard-kow-im111-unseated

(Iron Man I#110) - Wearing space suits and astride their atomic steeds as well as dragonfly-like ships, the Knights of Wundagore -- including Sir Lepard, Sir Lyan, Sir Ossilot and many others -- assaulted Arcturus' fleet. 

    Although the Rigellians were caught by surprise and initially reeling, the Knights considered that the Rigellians would recover and counter-attack; however, win or lose, they vowed they fight for the realm as true sons of the lost creator. 

(Iron Man I#111 - BTS) - The Rigellians in the ship carrying Iron Man and Jack of Hearts called an alert to battle stations as their space shields had been breached.sir_lepard-kow-im111-death

(Iron Man I#111) - Sir Lyan exhorted the other Knights to slay the invaders, and other knights noted that their power-lances ruptured the ship's hull, and they hoped that they might destroy the command ship

    When a blast hit a fuel storage cell, the explosion hurled Iron Man from the Rigellian ship into the middle of the attacking Wundagorians. 

    Sir Lepard announced this to Sir Ram, and what appeared to be Sir Lyan advised that this might be a destruct drone and ordered the others to attack it. 

    Seeking only to defend himself, Iron Man pulled the approaching Sir Lepard and Sir Ossilot from their atomic steeds.

    However, after the Rigellians fired in his vicinity, Iron Man dodged, but both Ossilot and Lepard were slain by the blast.

(Iron Man I#111 - BTS) - Siding with the out-powered Knights, Iron Man destroyed the Rigellian command ship's main gun, but both forces considered him an enemy due to his assaults, and combined blasts knocked Iron Man to Wundagore II's surface where he crashed in a swamp.

(Iron Man I#112 - BTS) - Ultimately the main Rigellian force -- via the Recorder#211 -- stripped Arcturus of power for his actions, and the Knights of Wundagore retained control of Wundagore II.

Which one is Sir Lepard?

  In Thor I#134, the armors shown in the fully-armored Knights don't match those shown when they aren't wearing their masks, so it really hard to tell who is whom.    
    Neither knight being spun about seems to be wearing armor similar to that worn by Sir Lepard as seen in his helmet-less form a few pages later. 
    And none of them are identified with their helmets off...their faces are first identified in
the Official Handbook of the Marvel Universe II (Deluxe Edition) #15: Wundagore entry (March, 1987)

    There are two guys in Thor I#134 who appear to be very similar:
    The pale guy who face is not seen when they getting knighted here has the same uniform as the guy who looks most like Sir Lepard in the other panels.
    However, the more orange guy to the far right of the panel when they are getting knighted also looks more like Sir Lepard in that panel. Who knows for sure...


    Although not identified, one of the guys in Tales to Astonish I#96 is suspicious for being Sir Lepard (see the left and right images here)...longer hair, but then he'd gone savage...

    I'm going with the assumption that the Sir Lyan, Sir Lepard, and Sir Ossilot in the Iron Man issues and X-Men Annual#12/3 were the same as the ones from the Thor issues, and the various Official Handbook  of the Marvel Universe entries on the New Men and Knights of Wundagore supports that, as do the Official Index to the Marvel Universe entries for the relevant issues.

    That being said, if the battle with the Other took place in 1958 (both Marvel and real time...although that may have been retconned...), and we know that over half of the 42 extant Knights of Wundagore perished in that battle, it doesn't seem unreasonable that the Sir Leppard seen in X-Men Annual#12/3 might have been a precursor of the Sir Lepard encountered over 50 years later in Thor I#134.

    Being different incarnations would explain the different New Men being knighted alongside Sir Lepard in various issues, and it might also explain why Sir Hogg did not have the pig snout of the Sir Hogg in the Iron Man issues.

    However, that is also problematic, as there were not female New Men (besides Bova) prior to the arrival on Wundagore II, so the Evolutionary would have had to created a new successor, rather than any sort of reproduction/succession.

    Going purely by Marvel Time (which is roughly one year per 4-5 years of real time), the devolved New Men were present on Wundagore for close to 3 years before being re-evolved. It's anyone's guess how quickly those animals would have reproduced vs. how many were consumed by predators, and it is further unknown if when the radiation from the Rigellian ship re-evolved the New Men if their offspring were then evolved for the first time. 

     Leopards are of the species Panthera pardus, one of the five existing species of the genus Panthera.

    Thanks to David Zuckerman and Loki for providing me with higher-quality images from Tales to Astonish I#96 and the OHotMU.

Sir Lepard
should be distinguished from:

"Lady Panthera"


(West Coast Avengers Annual#3/3 (fb) - BTS) - After arriving on Wundagore II, the High Evolutionary used the menagerie of animals contained in his citadel to evolve a female of each species he had already evolved for his knights.

(West Coast Avengers Annual#3/3 (fb)) - The High Evolutionary presented the women to his knights, and Sir Lepard (or another leopard New Man) accepted the leopard woman to take as his wife. The Evolutionary told the couples to go forth into the new city and to be fruitful and multiply; he further advised them that he had exhausted his stores and that from then on, they would be responsible for replenishing their numbers.

(Tales to Astonish I#94/2 (fb) - BTS) - Their little civilization thrived and flourished in peace and prosperity initially. 

(Tales to Astonish I#94/2 (fb) - BTS) - The New Men began reverting back to their bestial heritage, and they savagely attacked each other. The process began so gradually that the High Evolutionary did not notice right away. 

(Tales to Astonish I#96/2 - BTS) - The Evolutionary eventually subjected himself to his Genetic Accelerator, became a being of psionic energy, and devolved all of his Knights/New Men back into purely animal form.

--West Coast Avengers Annual#3/3

Note: The leopard woman was only seen in a single panel of a flashback in
West Coast Avengers Annual#3/3. If she did not perish in or before the savage battles on Wundagore II, she would have been turned back into a conventional leopard by the High Evolutionary, and assuming she continued to survive, she would most likely have been re-evolved into humanoid biped form by Rigellian radiation circa Iron Man I#111 (fb).

     She may or may not be the mother or earlier ancestor of the Sir Lepard seen in Thor I#422.

     We have no name for her...she would likely have the title Lady or perhaps Dame, and then she could Panthera, Pantha, Leopardess, Leoparda, Parda, or something along those lines...
