Powers/Abilities: King Simian appeared to a humanoid-chimpanzee (or bonobo, or something similar).

    He is apparently a super-genius, and he has the knowledge and technology to create a time machine able to transport materials, at least, into the primordial past.

    He could further create a "devolving agent" intended to drop evolution back a level when injected into Earth's primordial ooze.

    King Simian was served by a group of at least three Primateers (King Sapien had at least six, but only three were shown for King Simian), who were either chimpanzees or similar ape-men.

   

Height: Unrevealed (approximately 5'-5'6"; he looked much shorter than Ace & Jacquie, but he was never shown directly next to them)
Weight: Unrevealed (approximately 130 - 150 lbs.)
Eyes: Unrevealed (only seen wearing goggles; likely brown
Hair: Black
   

king-simian-zooHistory:
(Amazing Fantasy II#15/6 - BTS) - On the Earth of Reality-67171, a world apparently run by dinosaur-men, the human eco-terrorist King Sapien led his Primateers in a plot to use his time machine to send his devolving agent into Earth's primordial ooze and drop all of the dinosaur-people down to his rung on the evolutionary ladder.

    G.R.A.M.P.A. (the Global Reaction Agency for Mammal/Primate Affairs), sent the duo Blackjack (Ace and Jacquie) to stop King Sapien, and they located and broke into his base. Recognizing the pair, King Sapien had his Primateers engage them while he finished his efforts. Defying Ace's announcement that he was under arrest by the authority of G.R.A.M.P.A., Sapien replied that they would see how long their authority lasted once he had devolved them as planned. Refusing to allow this, Ace fired an explosive round into the time machine, and their was a bright flash of light.

(Amazing Fantasy II#15/6) - On the Earth of Reality-616, the human Blackjack members proclaimed their victory, while King Simian (who, like his Primateers, was an ape-man) was perplexed, as he felt that his plan had been perfect and should have worked.

(Amazing Fantasy II#15/6 (fb) - BTS) - Blackjack imprisoned King Simian and his Primateers in a caged habitat in the Bronx Zoo.

(Amazing Fantasy II#15/6) - King Simian warned Ace that the next time, he would succeed and devolve them all, but Ace taunted him as a "silly monkey," assuring him that that would never happen, "not as long as the law (Darwin's) was on his side."

Comments: Created by Dan Slott and Pete Woods.

    I don't think I appreciated the details the first time I read this, but the story appears to have been written as if King Sapien succeeded, but the devolving agent affected everyone, re-writing the past so that while the dinosaur-people were now humans and he and his human Primateers were now ape-men.
    However, affecting the past typically just diverges an alternate reality, and so it diverged Reality-616 from Reality-67171.
    What's more complex would be figuring out what happened in each reality.
    In Earth-67171, presumably nothing happened, as the divergence did not affect their reality, and King Sapien was arrested by the unchanged dinosaur-people Ace and Jacquie.
    In Earth-616, presumably thing proceeded very similarly to the events on Earth-67171 (with the notable exception that humans were the conventional species and King Simian and his Primateers were ape-men), as everyone was in-place and Sapien used his time machine to send his devolving agent to the past.
    What is unrevealed is whether King Sapien also succeeded, in which case Earth-616 would have been unaffected, but another reality would have been diverged where the dominant species were ape-men, and then King-something was one level below that, perhaps some lower primate...and the effect could have been perpetuated through multiple realities. But, it also could have been that Ace shot Simian's machine before the devolving agent was sent back in time, and so no other reality was diverged.

    Beyond the reality-alteration, I don't think we know how/why King Sapien was an ape-man with super-genius intelligence.
    I'm also not sure that a conventional habitat in a zoo is a secure place to imprison a criminal genius with simian physical abilities, but...what's the difference, it was fun anyway!

    Both Earth-99476 and Earth-66755 have sentient civilized dinosaurs in the modern day, but also minority human population. Does us seeing the exact divergence make it definitely distinct from the others?
    --HBK123
    Debatable for sure. I think the divergence is convincing for a designation. I THINK Dan Slott's thought process or intention was likely that the first reality was re-written into the second, but that's not typically how time travel works in the Marvel Multiverse. But that thought process (which is an assumption) makes me think that it was intended to be an unique reality:

Earth-67171 Ruled by dinosaur men, with a smaller human population. Despite efforts of Blackjack and agents of GRAMPA, King Sapien used time machine to send a devolving agent into Earth’s primordial past, diverging this reality from Earth-616, which mirrored the devolved situation.
