Yellow Radio

イエロー・レディオ

Abilities: Judgement Blow, Silly-Go-Round
Being the Yellow King makes Yellow Radio a very powerful and commanding figure. He is also a cruel and manipulative individual, as he was the one who stole the chrome disaster armor and essentially created the fifth one in order to exploit the rules that allow him to kill the Red King.
He, along with the Kings of Pure Color, attained level nine and decided to create a treaty that separates their territories and disallows fighting amongst each other to obtain level ten.

Spoiler

Yellow Radio's abilities rely on illusions in order to disorient his opponents. However, since he is the Yellow King, he is able to battle Black Lotus on equal grounds. His weapon is a baton that is apparently strong enough to withstand strikes from Black Lotus' blades. It was possible due to its special effect, which is that the more times it spun around, the more powerful it becomes.
