Monsieur Mallah

Monsieur Mallah is a sentient gorilla who is a member of the Brotherhood of Evil and the Brain's most trusted confidant and second-in-command. Like The Brain, he was voiced by the late Glenn Shadix.

Character History
Mallah started his life as a normal gorilla, but his intellectual (and perhaps also his physical) capabilities were greatly enhanced by a great, yet unknown being, who was also said to have created The Brain. Somehow, Brain managed to convince Mallah to join his villanous schemes.

Monsieur Mallah was once sent to kidnap Melvin, Timmy Tantrum and Teether, three pre-adolescent superheroes who posed a threat to the Brotherhood of Evil. Mallah continuously attacked them, trying to capture them, while Raven kept protecting the kids from him. He eventually succeded in kidnapping the young trio, but at that moment they revealed their true powers and, with the help of Bobby, defeated Monsieur Mallah without Raven's help.

During the final battle in the Brotherhood's base, Mallah almost turned the tide of the battle, but once he realized they had lost, tried to escape with the Brain. Beast Boy knocked him back into the base and into the Brotherhood's freezing machine, however, where Mallah (and a short while later his master as well) was subsequently flash-frozen along with the other villains.

Power and Abiliites
Monsieur Mallah's most remarkable attribute is his genius-level intelligence and his capability to think and speak like a human. Mallah is trained in various intellectual areas as well, including electronics, physics and tactics.

As for his physical abilities, he possesses a gorilla's natural strength and stamina, possibly greatly augmented by the Brain's tampering, which, along with his cunning, allows him to take down a wide range of superpowered opponents.
