Jabber Wonger

Jabber Wonger is a major antagonist in the Gachiakuta anime (voiced by Yuuki Shin in Japanese and Zeno Robinson in English). He's a member of the Raiders' Front Line, known for his extremely unhinged, psychotic personality and a violent obsession with fighting—particularly against strong opponents.

He's described as a masochist who derives pleasure from both inflicting and receiving pain, often sporting a wide, manic grin during battles. His behavior is erratic, sadistic, and chaotic, making him come across as pure menace and unpredictability in his appearances (such as in key confrontations like against Rudo or Zanka).

In the anime adaptation (which aired from July to December 2025, produced by Bones), his design and manic energy translate directly from the manga, with fans often highlighting how well his voice acting captures his insane, laughing demeanor.
