Pietro Zatara

Pietro Zatara, also known as Quicksilver and a variety of other titles, is a powerful mutant speedster and uncle to Damian Wayne, son of Magneta and Zeddicus Z'ul Zatara, and twin brother to Wanda Zatara, the Empress Mother herself, with whom both himself, his nephews, and his own sons, are engaged in an incestuous relationship. He is extremely close to his sister's son, Damian, whom he treats in a brotherly jokey manner, and is actually revealed to care more for Damian than he does his own son Criss, whom he does care a great deal for. He also has three older paternal half-brothers, Killian, Dash, and Bran Gardiner, themselves extremely powerful magi.
