Whatever, whatever, whatever, shut up!
Just to note, you only "drain" superpowers by ingesting bodily fluids. If the person whose body it is is normal, you just get a little hydration, if that. Also note that the process only gives you the superpowers--it doesn't take them from the other person. The name comes from the tendency of well-known power leeches to go around drinking people's blood--or, rather, for the power leeches everyone hears about to be the ones who go around drinking people's blood. Either way, the Leechs' image in the public mind is one of a bloodsucker. Finally, these could change with the right powers...

You grew up in Venice Beach, a nice town in Southern California, a center of the arts. Your friend, Patrick McBride, was a kid raised by a rich family in a poorer area of town. His father was a miser and his mother either apathetic or submissive, possibly both. On a similar hand, Dirk Carver [1], the birthday boy, was a rich kid, from a rich neighborhood, going to a middle-class school. You did, too, but the Carvers were a bit wealthier and you a bit less conspicuous about it (due in no small part to wearing your older sister's hand-me-downs), so you weren't quite as ostracized. Still, Patrick and his friend Nolan Elva Sloan (who likes to go by his middle name for some reason) were about the only kids in your class who chose to be around you rather than tolerating your presence or whatever. Elva was a nice kid, about average, but with good grades and autism. He assumed that those were why he was disliked, but it had more to do with his [2]. He was a kid who no one really liked, but no one really disliked either. He, you, and Patrick were friends as much because of your shared social status as because of your shared interests ([3]).
The party dragged on. Towards the end, there was one bottle of Coca-Cola left, which Patrick suggested the three of you split. After the party ended, you all went home. The next day, [4]...
1. Can random name generators come up with awesome names or what?
2. What was Elva's ability that set him apart from everyone? (Really powerful abilities would make people like or at least not shun him, so nixing that ahead of time.)
3. What interests did the three of you share?
4. What caused your power taken from (presumably) Elva to be noticed?
