Riptide was responsible for the death of Quiet Bill in Sinister's attempts to eliminate mutants with knowledge of the future in the early stages of the Messiah Complex, activating his powers while confined in an elevator with Bill.

During Messiah Complex in the final battle on Muir Isle, he seemed aware of the fact that his neck had been broken before. He was rendered unconscious by Professor X after knocking out Wolfsbane.
