Best bro friends forever.
Hayden is one of the last of my characters you would expect to have a ridiculously gay best friend.
Their relationship is very Hayden based. It's aaaaall about him. Tate is not a very trustworthy person and doesn't give much of himself out. He's pretty ruined as a person and has all sorts of mental issues and obsessions.
Tate actually has a weird genetic condition in which his body will change from male to female to male to female etc once every ten years or so, but can happen as early as 2 years. It is uncontrollable and every bit painful. Tate, as a woman, was in a relationship with Hayden twice. Once when they arrived on Earth, and another just recently, both times ending without the couple speaking to each other.
Tate loves Hayden but Hayden is very adverse to having a romantic and sexual relationship with a man. There is no doubt he loves Tate, but he's definitely not gay. BBFFs!
Tate is a Supia Dolls Zion
Hayden is a Migidoll Ryu
