Appearance
Rosie is a young man with light colored eyes and hair that is parted to the left and has an undercut. He wears a grey suit with a white shirt underneath and a diamond patterned tie.

Personality
Rosie is very ambitious and plans to revolutionize psychology and logic in martial arts. Deep inside, he is huge coward who easily willing to do anything to survive even it means abandoning his martial art style and his own humanity for the sake of surviving as he is the first one to rush to eat the Monster Cell.

As a monster, he is quite vengeful and sadistic since he beats a heavily injured Dave to avenge his humiliating defeat in the first round of the tournament.

Monster Raid Arc
Rosie is participating in the Super Fight Tournament in C-City at the C-City Super Stadium. This is the first time Rosie has participated in the tournament. While watching the match between Max and Suiryu, he was shocked by the latter strength, easily defeating his opponent. He was matched and defeated by Dave without much difficulty. On his way to the hospital, he is taken hostage by The Three Crows, along with Dave and Bazuzu.

After becoming Monster from eating Monster Cell, he sadistically throws a heavily injured Dave into the distance to avenge his defeat in the tournament. However, his victory is short live since Choze quickly snaps his neck 360 degree killing him.

Fighting Style
Psycho Analysis Martial Arts (心理分析格闘戦術, Shinri Bunseki Kakutō Senjutsu): Has not been shown yet. He analyzes his foe's psychology and turns it in his favor. This style is actually useless in the fight since he was crushed by Dave in mere seconds before he can even react. Although it is worth noting that since Dave's style is simply crushing people, it is possible it at least doesn't work on extremely simplistic styles like that one.
