Dr. Cossak

Cossak (コサック) is a character from MegaMan Battle Network 3.

Games
When he worked at SciLab, he was in charge of the project that created Bass. Years later, he tries to stop Bass in MegaMan Battle Network 3. He's first seen during BubbleMan's attack, where he helps Lan modifying the PET to allow MegaMan pass by small areas. When MegaMan fights against Bass in the Undernet and is knocked out, Cossak's NormalNavi appears to fight against Bass, being almost deleted, but Bass leaves when Wily called for him saying he has the four TetraCodes. Cossak hears this and suspect they are trying to awaken Alpha. In the WWW's base, Cossak appears to help Lan and the others, and is hurt by Bass. He's taken to the hospital and Lan tells him what happened in Castle Wily.

Manga
Like the games, Cossak was in the project that created Bass in the MegaMan NT Warrior manga. He appeared in a side story telling Bass' origins.

Trivia
Although he has the same Japanese name from his original counterpart, his name was translated without a "c" in the MegaMan Battle Network series.
