History:

(Marvel Apes I#2/1 - BTS) - The alien-powered manipulator Moonstone became part of the Thunderbolts at an unrevealed point in time, serving alongside teammate Mach IV.

(Marvel Apes I#2/2 - BTS) - Moonstone was presumably present when Venom (Mac Gargan) flung his feces at the team after which Bullseye showed how deadly he could be.

(Marvel Apes I#3/2 - BTS) - Moonstone and Thundermonks faced off against Monk Knight (Marc Spector).

(Marvel Apes I#2/1 - BTS) - Moonstone and MACH IV became part of the Outcasts, which emerged as a loose resistance within the simian world, formed by super-powered apes who had learned a truth most refused to face, the heroic Captain America was no patriot at all, but a powerful über-vampire (secretly the undead Baron Blood in disguise). The Outcasts saw the danger and united in secret to oppose the growing corruption within their world's heroes, operating from the Sanctum Sanctorum, the former home of the late Doctor Strange, their sanctuary was mystically concealed within a shared memory and could only be reached through the Monkey's Paw. To most simians, the Outcasts were little better than the criminals they opposed and were actively hunted by "Captain America's" Ape-Vengers.

(Marvel Apes I#2/1) - Moonstone was present at the Sanctum Sanctorum when Speedball brought Dr. Fiona Fitzhugh and the Gibbon of Earth-616 to their hidden refuge to safe them from "Captain America", the Fantastic Four and Ape-Vengers after being accused for killing Reed Richards.

(Marvel Apes I#3/1) - Moonstone, Storm, Iron Paw and the others chased the Gibbon, forcing him towards Wolverine after which the Gibbon accidentally fell into the Dark Dimension, crowded by the dangerous Mindless Ones.

Comments: Created by Karl Kesel.

Both Marvel Apes I#2 (December, 2008) and Marvel Apes I#3 (December, 2008) included a Bonobo-Pen Bulletin letter page that established that several Marvel Apes variant covers at the time were part of their reality with fun little solicitations of those issues. In the Bonobo-Pen Bulletin letter page for issue 2 the Thundermonks (Thunderbolts) were mentioned in the solicitation for Thundermonks #115 and for issue 3 they were mentioned in the solicitation for Monk Knight #21. The Thundermonks supposedly included Moonstone, Bullseye, Penance, Radioactive "Monk", and Venom (Mac Gargan) although their inclusion into Earth-8101 should be taken with a grain of salt. The fact of the matter is that they are just that, variant covers of other series and the narratives seen on them aren't necessarily a reflection of what happened on Earth-8101, especially in this case there is no Penance on the Marvel Apes planet but only Speedball as the story made an important point that this Speedball remained the ever-positive hero instead of the doom-and-gloom Penance of Earth-616. Included on the right is the variant cover to Moon Knight V#21 (August, 2008).

The Marvel Apes limited series (2008) was conceived as a playful companion to the earlier Marvel Zombies phenomenon. Following the unexpected commercial success of Zombies, Marvel looked to replicate the formula by reimagining its superheroes in another offbeat, high-concept alternate reality. Writer Karl Kesel, inspired by Silver Age whimsy and the classic "What If?" tradition, pitched a world where Marvel's heroes and villains were evolved primates rather than humans. The project was greenlit as a four-issue miniseries, launching with a tongue-in-cheek promotional campaign that leaned into its absurdity while still delivering a surprisingly dark, satirical storyline. The series spawned several tie-ins and one-shots, positioning the Ape-Verse as both a parody of and homage to Marvel's multiverse storytelling.

Earth-8101 is the main Marvel Apes reality, but there are three others as well:
  - Earth-81218, possible future of Earth-8101 set in the year 2099.
  - Earth-90543, monkey Speedball was send back to his world and branded a traitor by the Ape-Vengers. This was a bad dream of the Gibbon.
  - Earth-95019, diverged from 8101 when zombies invaded their world. The reset button was eventually pushed on the original Earth-8101, preventing the divergence.
