Omega Care Unit

The Omega Care Unit is a special medical suit created by Dr. Ivo Kintobor to care for Buns Rabbot. Buns protects Dr. Kintobor in the suit after he saved her from her Neuro-Immuno Deficiency Syndrome by building it for her. It was partially destroyed, however, by Rosy the Rascal while Buns was fighting her in it.

Creation
The Omega Care Unit was made as a life-support suit for Buns Rabbot, after she was left for dead by the Anti Freedom Fighters and was rescued by Anti Robotnik who placed her in the care of the Omega unit to prevent her NIDS from spreading. Since then, Buns has served as a protector of the kindly Anti Robotnik in the suit. (StH: #193)

Assistance against the Suppression Squad
Later, Buns mistook Sonic for Scourge and attacked him and Amy Rose, after they came out of a dimensional portal into Anti Robotnik's home to try and find assistance against the Suppression Squad. Buns later accompanied them to Castle Acorn to find Anti Amy, otherwise known as the Rosy the Rascal, to defeat Scourge. (StH: #193)

Rosy attacked them, saying to Sonic "You're a Sonic! My Scourgey is a Sonic! I want to smash Sonics!". Amy Prime then retorted, stating that they were like sisters being couterparts, but Rosy wanted to defeat her nonetheless. As the four engaged in battle, Buns used her riot foam in an attempt to prevent her from moving, though Rosy simply destroyed the foam with her hammer, at which point Buns said "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 went on to keep Rosy distracted so that Buns and Sonic could locate the Globe Posts that had been stolen from Anti Robotnik before. Buns was concerned about leaving Amy to fight for herself, though Sonic informed her she could take care of herself. (StH: #194)

Near Destruction
Buns then protected Sonic while he went through the Globe Posts to see what was going on in Mobius. But Amy was defeated and Rosy tried to destroy the Globe Posts, but Buns fought her and lost as Rosy managed to crush a fair part of the Care Unit leaving her defenceless. Luckily, the suit still had some power left that she used to fly out of the Anti Castle Acorn and back to Dr. Kintobor's tower and told Amy to "give that brat a whuppin' for me." (StH: #194, #195)

Abilities and weaknesses
The Omega Care Unit's main ability is creating a stasis field that prevents Buns' N.I.D.S. from progressing and supports her immune system. It also has added battle abilities that were grudgingly included by Dr. Kintobor after Buns requested them. These include quick-hardening riot foam, spellbinder waves that make the victim dizzy and added strength. It also has rocket boosters on the bottoms of its feet and one on its back that allow it to fly. The care unit's major flaws, however, is that its weapons are very weak and that it lacks strong armour which proved to be its downfall. (StH: #193, #194, #195)

Background information
The Omega Care Unit bares a heavy resemblance to a character in the Sonic the Hedgehog video games called E-123 Omega, possibly meaning he will be introduced to the comics soon, as the care unit would serve as his alternate counterpart.

Originally, the Omega Care Unit's prototype design resembled E-102 Gamma more than Omega, but it was changed to Omega's "since it seemed to lend itself better to housing a mobian, and it seemed much more apt for her [Buns'] character." According to Ian Flynn.
