Description

Sinister first fought the X-Men during the "Inferno" crisis, an invasion of demon mutants he helped create. He sometimes aids Charles Xavier's team, but for his own reasons. Sinister helped Gambit save the savage Sabretooth's life, and assisted the X-Man again when he became trapped in the 19th century; took in the mutant Threnody and provided her with devices to control her energy releases; and returned Courier, a messenger with the ability to control every molecule in his body, to a more human state. In almost every case, however, Sinister exacts a price very costly to the soul.
