Immanis is an evil Haos Bakugan of the Abyss Brigade.
A monster of a Bakugan, Immanis is a force to be reckoned with. He uses his brute force wisely, and can dish out attacks that make the opponent deal with massive amounts of damage. He is also extremely skilled at strategy. His tentacles are able to paralyze the opponent using a slow-acting poison, and Immanis' eyes can be used to hypnotize opponents. Despite these characteristics, his appearance alone is enough to send foes fleeing in terror.
In human form, he is a handsome spectator, which is ironic since in Bakugan Form, he is a hideous monster whose looks can frighten even the most courageous of Bakugan.
Immanis is a Bakugan with an extremely short temper. He is easily annoyed and will attack anyone who bothers him the wrong way. Despite these traits, Immanis is very kind and helpful, though he despises having to be told to do something while doing an activity he likes. However, he is only kind to the females on his team, thus giving him the nickname of "The Hideous Ladies' Man", due to the fact that he is a hideous Bakugan in his true form. Immanis is also sneaky and cunning, and hardly shows any mercy at all in battle.
Immanis makes his debut in ...And the Clock Starts Ticking when using his Abyss Brigade teammates in battle, while he is disguised as a human Brawler. In the end of the episode, he reveals his true form - a hideous Bakugan.
