Chikin

 A funky little birb from an oasis on Earth.

It was born with a birth defect that caused the feathers on his head to stop growing, basically making him a bald birb. 

While stuck in the Human Realm, Eros spotted the weird birb and instantly grew attached to it, due to it's friendly nature. Eros then went ahead and adopted the funky guy later on, even naming it Chikin, because it "looks like a very fluffy bald chicken".

Now Chikin and Eros are basically inseparable
