Suke-San

Suke-San is confident and somewhat mocking because opponents usually have no reliable way to see him. His invisibility lets him attack from unexpected angles while avoiding direct retaliation.

He becomes less composed once his primary advantage is neutralized and he is forced to fight as a visible target.

Suke-San's defining trait is complete natural invisibility. Unlike a camouflage technique or transformation, it does not require active concentration and leaves opponents unable to visually identify his position.

He is also a competent hand-to-hand fighter. The combination of ordinary martial skill and invisibility allows him to repeatedly strike Yamcha before the latter can react.

His weakness is that his body can still interact normally with physical substances. Covering him in something visible reveals his outline and removes most of the tactical advantage.

Suke-San enters Fortuneteller Baba's tournament after her first fighter is defeated. Yamcha volunteers to face him but struggles because he cannot locate the invisible opponent.

Yamcha initially begins tracking Suke-San by listening for his footsteps, but Baba interferes by making enough noise to conceal them.

Krillin eventually develops an unconventional solution. He arranges for Bulma and Master Roshi to face one another, provoking Roshi into a massive nosebleed that splashes over Suke-San and renders his outline visible.

Once he can see the target, Yamcha uses the Wolf Fang Fist to defeat him.

Fortuneteller Baba employs Suke-San as one of the five supernatural fighters guarding access to her divination services.

Yamcha becomes his opponent and defeats him once his invisibility is neutralized. Krillin devises the method that exposes him, while Bulma and Master Roshi become unwilling participants in the plan.
