Yassen Gregorovich

Yassen Gregorovich was a Vortixx, and was one of the best assassins in the Matoran Universe. He was hired by Blackout in order to bring Ynot to Destral, a mission that he survived. He was also the former owner of one of three armour-piercing heat guns in existence. Ravat assaulted him and stole it, while also removing one of his arms and an eye. From that point onwards, he decided to use a wheelchair, despite both of his legs being fine.

His status is unknown after the destruction of the Matoran Universe.
