Greed is an Alicorn who is in truth, not that greedy.
Next to nothing is know about Greed's past. Where he came from and why he showed up is a complete mystery.
Greed is just that. Greedy. He is modest about it, however, but whenever he does something he'll always figure out a way to get something out of it for personal gain. Greed is generally laid back and doesn't like to work, and his rebellious nature sometimes gets him in trouble with the others. He is usually partnered with Lust, as she is the only one who can keep him in check. Due to this, he has a dislike for Lust, and doesn't like to be around her. Greed almost never instigates a fight, and usually waits until someone else makes the first move before engaging. In a fight, he relishes the feeling of pain and loves it when he is against an equally matched or more powerful opponent. He seems to have taken a liking to Lightblade, as their personalities are somewhat similar on the rebellious nature, and they can both go head-to-head against each other in a fight.
