Ribby

Ribby (アバラ) was one of Doctor Garaki's intelligent High-End Nomu that he kept in his lab under Jaku General Hospital. He and his kin act as some of the secondary antagonists of the Paranormal Liberation War Arc.

Appearance
Ribby possesses a humanoid appearance, like nearly all the other Nomu, though also features a long antennae-like head, which has the capacity to extend to greater lengths.

Personality
Being originated from the body of a killer, Ribby acts incredibly unhinged with his immediate desire to kill the Heroes once being awoken. He also possesses some semblance of intelligence, as he is able to recognize and understand his environment and opponents, and uses that to his advantage.

History
Before being turned into a High-End Nomu, Ribby was once a psycho killer. He was carefully selected by Doctor Garaki to be made into a Nomu for this reason.

Paranormal Liberation War Arc
As the heroes start their raid on Jaku Hospital, Doctor Garaki prepares to use Johnny's Quirk to warp himself and Tomura Shigaraki to safety. Before he can, however, Mirko bursts inside his lab, inadvertently killing Johnny in the process.

The now trapped Doctor releases five High-End Nomu, one of them being Ribby, in an effort to push Mirko back as he tends to Tomura. Ribby, under the impromptu leadership of Woman, proceeds to attack the Hero. However, due to being released early without stabilization time, they are easily pushed back by Mirko.

Eventually throughout the battle, as the stabilization kicks in and the High-Ends become more comfortable with their bodies, they are able to much more freely defend themselves and attack Mirko. Knowing this, she proceeds to try and escape and head toward the Doctor and Tomura's location, but Ribby uses his antennae to quickly extend itself far along, catching up and grabbing ahold of Mirko before she can destroy Tomura's capsule.

He makes his way over there to stop her, but is surprised by Endeavor who slams down right on his head, allowing Mirko to break free and destroy the capsule. Eraser Head arrives and uses his Quirk on some of the High-Ends, including Ribby, so that they will be much easier to destroy, however having figured out Eraser Head's trick, Woman distracts him long enough for Ribby to take advantage and once again use his antennae to pierce through Mirko, cutting through her chest and legs and cutting off her ear, pulling her back before she is rescued by Endeavor.

He is eventually overwhelmed by the rest of the Pro Heroes that soon arrive to assist, and then alongside the rest of the High-Ends, is destroyed by Tomura's Decay.

Abilities
Overall Abilities: Like other Nomu, he was shown to be decently powerful.
