Who Wins This Magical Battle? 
 
                                                                                                         LEPRECHAUN

Voldemort without even trying. 
 
And that's me saying this as someone who hates the Harry Potter universe with a passion.

Leprechaun destroys Voldemort with ease. He can't die from the killing curse so what's Voldy going to do? Leprechaun can simply point at Voldemort and have a hole blow through his chest.

Bump.

This battle hinges on a few factors.

1. Prep or no prep? With prep, I can easily see Voldemort winning without even breaking a sweat. Without prep-...The Leprechaun at the full extent of his abilities is capable of reality warping (seen when he made a woman's breasts explode, and or turned a man into a slot machine) that outclasses Voldemort immensely.

2. How close are they? If the Leprechaun can not see Voldemort (due to constant apparations) then he's fried. If they're standing across from eachother, it could get interesting.

@kingjohnrocks: HP Wizards can warp reality and turn people into animals or objects as well, and the most recent movie had them pulling off some crazy inception level shit.

Does Leprechaun actually have any feats against other magical beings that would suggest immunity to killing curse or other spells?

I'm well aware of what Voldemort can do (I wrote his respect thread), however, that doesn't nullify my point. If he doesn't act fast enough, the Leprechaun could score a win. It's not likely, but it can happen.
