Hummingbirds usually feed themselves through flowers, but an anomaly during birth made Mr. Coliver have a dislike towards flowers. He found out though, that gold has something he actually likes, so that's what he feeds with, usually stealing the gold from others

Sincerely, I don't remember where the idea of the hummingbird came from, since it wasn't exactly from today, but from yesterday (before making Wafer Lily). And the gold... I just wanted to make something gold related. I first thought about a hummingbird made of gold, but my ideas directed toward a weird gold hummingbird X-men.

Moustache, beard and eyebrows are so he can be distincted as sir. "Coliver" is a mix of "Colibri" (hummingbird in spanish) and "Oliver".
