Marvel: Calcium Generation

Janos Quested (Riptide)
Riptide is a mutant with the ability to spin his body at incredibly fast speeds. When he spins, he can generate calcium growths from his bones that protrude through his skin, often taking the form of shurikens and spikes. The additional velocity that comes from his spinning making them lethal missiles that can even punch through steel. He can also create a vacuum suction that draws in nearby objects and also acts as a high-powered sling for objects. Another ability is to be able to make only parts of his body spin, such as only spinning below his head or torso, allowing him to taunt his opponents.
