7. Larfleeze

So around 2007 we got a fairly basic idea: "Hey, what if Sinestro made his own Yellow Lantern Corps?" And then that idea turned into the most obvious "How did no one think of this idea before 2008?" idea ever: "We have a Green Lantern Corps, and now a Yellow Lantern Corps, so why not ALL OF THE OTHER COLORS?"

Well, not ALL of the other colors. We don’t have a Puce Lantern Corps or whatever, but the point stands.

Larfleeze was a member of the Orange Lantern Corps. The Orange Lanterns are known for their powerful greed. And by LanternS, I really mean Lantern, because there is only one of them. That's brilliant. So the greediest being in the galaxy is Larfleeze the Orange Lantern, otherwise known as Agent Orange.

He is a furious hoarder Muppet who just wants to accumulate more stuff. He's also capable of generating his own army using his ring, making him truly a one-man Lantern Corps.
