Peter Stark, the Speedster

Whoosh! Silver-Haired Peter abruptly turned to look at Peter and Strange beside him. Then, silver light glimmered around him, and he appeared before Peter and Strange almost as if he had teleported. Peter frowned slightly. In that instant, he had felt Silver-Haired Peter examine him from every possible angle. That meant this Silver-Haired Peter was incredibly fast. And the silver glow released from his body while moving at high speed reminded Peter of someone. "Quicksilver," Pietro Maximoff! Wanda's younger brother.
