Shifters' appear in the game X-Men Origins: Wolverine. The only effective way to combat these blue teleporters is with Fury moves and counters. They set up barriers around Wolverine and jump around at will. They use hand-to-hand attacks, and counters are the best surefire way to get some blows in. If there are a lot of them, Fury moves can help a great deal, but Shifters have plenty of health.
