Paradox from Ben 10 does that which on itself a reference to Dr.who. If i remember correctly, its not that he got powers from being sucked into the time portal but that his mind expanded allowing him to travel among other stuff.

from the wiki: Paradox was displaced outside of time, where he lost the ability to age and was unable to sleep or eat; just exist. He went insane for a while, but then got bored and regained his sanity. Gaining complete understanding of the space-time continuum, Paradox forgot his original name in the process
