Either Wanda or quicksilver

I had to do a double take when I saw Quicksilver. I legitimately thought it said something nsfw. 😮‍💨

I like Quicksilvers the most, as he has a Speedster physiology and can run at speeds beyond mach 5 and has full control over his speed and heightened reflexes allowing him to maintain both a normal life and teach himself at an accelerated rate and retain all the knowledge as he's seen reading multiple books in a matter of moments without damaging them and teaching himself to play and instrument in mere moments. So the practical applications for his powers are practically limitless.
