Quicksilver (X-Men Evolution)
From Multiversal Omnipedia
Quicksilver, alias Pietro Maximoff, was the son of Erik Magnus Lehnsherr, alias Magneto, and brother to Wanda Maximoff, the Scarlet Witch. He has the ability to move at superhuman speed, up to supersonic speed, and is highly arrogant. He was loyal to Magneto above all else (unlike his sister Wanda), and he worked for his father both directly and through the Brotherhood of Mutants. He has a strong rivalry with Spyke, which began when they were on the same basketball team in high school. Quicksilver and the Brotherhood temporarily teamed up against Apocalypse, with Pietro and Wanda confronting their father.
