From "Kamen Rider Double"

Violence Dopant:http://i231.photobucket.com/albums/ee121/Kainsword17/Dopants/08aViolenceDopant.jpg

Tsuyoshi Ageo is Wakana's manager, a weak willed man who loves her in spite of the abuse. Ageo is used by Wind Wave DJ Motoko Saeki in a scheme to force Wakana off the air, giving him the Violence Memory she buys. Overcome by the Memory's influence, Ageo assumes the alias of "Mister Question", targeting certain places of value to Wakana and portraying himself as a stalker. As the brutish Violence Dopant, his left arm is strong enough to destroy anything in its path, even enough to smash through cars. He can compress his body into a wrecking ball-like form called the Violence Ball http://i231.photobucket.com/albums/.....ntballform.jpg to cause more collateral damage. Once discovered, he abducts Wakana and is chased after by Kamen Rider Double. Before being defeated by means of LunaTrigger's Trigger Stag Burst Maximum Drive, he leads Wakana to Motoko.
