Parents: Elizabeth Walters x Charles Xavier

Oldest to youngest:

Lucifer Zachary Xavier

Mutation: Mind Murder

Alias: Satan

Lucifer has the ability to kill people with his mind. This is one reason his alias name in the field is Satan. The other reason is that he has a set of horns growing from his head

In reality, he's quite loving and gentle natured

Sean Cassidy Xavier

Mutation: Time Manipulation

Alias: Tik Tok

Named after Elizabeth's late friend Sean Cassidy, Sean is the middle child and just as protective of his youngest sibling as Lucifer is.

Lily Jayden Xavier

Mutation: Levitation

Alias: Pixie

Lily has the ability to levitate herself and others as well as inanimate objects

Lily is the youngest out of both sets of triplets--the Xavier triplets are younger by about a year--and is well loved by everyone around the X-Mansion. She's a complete Daddy's Girl, too. 

If she so much as makes a noise of discomfort she's flocked by her three cousins and two elder brothers.

A/N: Yeah, I don't know but I just really really love these children!!
