Iggy is in pretty much all of my AU's at least a little bit weird in one way or another. Is crazy enough to own a Chainchomp? Absolutely. (Koopa AU's).
Or to have two dogs in a castle with many other animals? Hey, it wasn't his fault that the dog didn't connect with Junior at first, but did with him, causing him to get two dogs as his pets. (Human AU).
Loving a undead technically predator? Of course only he would... (Partner AU).
Or be such creature himself? Also correct. (Mythology AU).
But what other weird thing does he have/is he in other AU's?...
Other thing (not important for the AU's hints)
Since my main Iggy has the same Epilepsy as I have, he has had a head surgery as well (we share the pain together).
He has the same nice head bandage as I do.
