Who knows, maybe I'll have a whole story arc where Java gets himself a Green Lantern Power Ring and he has to defeat Thanos and Mephisto. See, the Green Power Rings run on Willpower, which of course jaguars have an abundance of. Also, caffeine boosts Willpower, which is why half of corporate America runs off of it. Java Lantern would be indomitable.

And for those of you not quite ready for Java as a Green Lantern. Here is the B&W line art version and you can imagine he is a White Lantern instead.
