Buns Rabbot, formerly known as Anti Bunnie or Evil Bunnie, is Bunnie Rabbot's Anti-Verse counterpart from Anti-Mobius. She was one of Evil Sonic's girlfriends until she found out he was cheating on her with Anti-Penelope Platypus, and she subsequently sought revenge against him. Anti-Bunnie was once a member of the Anti-Freedom Fighters, but Evil Sonic (at this point renamed as Scourge the Hedgehog) kicked her out of the group after she developed Neuro-Immuno Deficiency Syndrome (NIDS), a degenerative illness. After being left for dead, she was rescued by Doctor Ivo Kintobor, who placed her in the care of the Omega Care Unit to prevent her NIDS from spreading. Since then, Buns has served as a protector of the kindly Julian Kintobor.
Anti-Bunnie was first encountered by Sonic Prime when he was sent into Anti-Mobius by Evil Sonic. During a brief battle with the Anti-Freedom Fighters, both Anti-Bunnie and Anti-Sally Acorn were thrown into toxic vats containing Octopods.
Health Crisis and Change of Allegiances
In the interim period between Scourge's return to Anti-Mobius and his invasion of Mobius Prime, Anti-Bunnie developed N.I.D.S. The disease first manifested in her spinal column, with the ensuing damage to her neuromuscular system leaving her paralyzed from the waist down. No longer of any use to him, Bunnie was- in her own words- "left for dead" by Scourge.
"Buns" would have ultimately died, succumbing to the effects caused by the unchecked degeneration of her neuromuscular system, if not for the humanitarian intervention of Dr. Kintobor. The Doctor, long familiar with Scourge/Evil Sonic's ruthlessness, built the Omega Care Unit to halt the spread of the disease. The armored suit would maintain and support Buns' health and vital functions as Kintobor worked on finding a cure, while also allowing her to protect the Doctor from the Suppression Squad during their efforts to obtain the Globe Posts.
She mistook Sonic for Scourge and attacked him and Amy Rose, after they came out of a dimensional portal into Kintobor's home in search of assistance against the Suppression Squad. Buns accompanied them to Anti-Castle Acorn to find Anti-Amy Rose, known here as "Rosy the Rascal", to defeat Scourge. Rosy stalked and attacked them, exclaiming "You're a Sonic! My Scourgey is a Sonic! I want to smash Sonics!". As they engaged in battle, Buns used her riot foam to immobilize her, only for Rosy to simply destroy the foam with her hammer. At this, Buns remarked "Ah wish ah'd been outfitted with somethin' a bit more proactive...like a missile launcher or somethin'". (Possibly a reference to E-123 Omega who is equipped with a missile launcher.)
After this, Amy stayed behind to keep Rosy distracted while Buns and Sonic located the Globe Posts that had been stolen from Anti Robotnik. Buns was concerned about leaving Amy to fight alone, though Sonic informed her she could take care of herself. Buns then protected Sonic while he used the Globe Posts to see what was going on in Mobius. Rosy broke Amy's hammer and then tried to destroy the Globe Posts. Rosy managed to crush part of the Omega Care Unit, leaving Buns defenseless. Luckily, the suit had enough power for her to fly out of the Anti Castle Acorn and back to Dr. Kintobor's tower, telling Amy "give that brat [Rosy] a whuppin' for me."
Buns later returned in her repaired Omega Care Unit to retrieve the Globe Posts from the Suppression Squad after they defeated Super Scourge. She was offered the chance to re-join them by Anti-Miles, claiming it was Scourge that wanted her out, and that with the OCU she could be a great asset to the group. But she quickly answered "Yer a creepy little cuss, y'know that?". Anti-Miles simply asked her to think about his proposition. Buns went with the Freedom Fighters back to Dr. Kintobor's tower with the Globe posts in hand.
