Janet van Dyne, the Wasp, is a founding Avenger. During the DISK project presentation at the Raft, Loki orchestrated a breakout that imprisoned her within an Animal-class DISK alongside other core Avengers. This classification arose from her insect-themed codename, despite her energy-based powers.

After containment, she linked to Jessica Shannon, one of five children acquiring partial Biocodes. Jessica held the specific Animal Bio-Code needed to release Wasp. However, damage to the Biocode Installer meant Wasp could only manifest for brief periods—typically five and a half minutes—before returning to the DISK. While confined, she communicated via holographic interface.

Her abilities included shrinking to miniature size, flight via bio-synthetic wings, and firing bio-electric energy blasts called "wasp's stings." In combat, she used her small size and agility to dart through danger, employing hit-and-run tactics or targeting environmental weaknesses. She demonstrated resourcefulness on missions, coordinating with teammates to distract or outmaneuver foes like MODOK or Whirlwind.

As Jessica's partner, she offered guidance during battles, their dynamic emphasizing teamwork over overt mentorship. Her personality reflected prior heroic experience, showing confident leadership in crises and strategic thinking during Avengers operations. She participated in efforts to thwart Loki's global schemes with the children and other heroes, contributing to missions targeting scattered DISKs.

Her documented role focused on the collective effort to reclaim DISKs and counter Loki's influence alongside the Avengers and their young allies.
