They all suit their names.
Mischief- well no exclamation needed. The name says it ALL.
Tinkerbell- so danged cute and dainty. lol. But a knack for getting in trouble.
Phoenix- Oh Phoenix

Well to understand her name you have to be a Marvel geek like me.

Well in X-Men there is Jean Grey. When she is on the X-Men she is Dr. Jean Grey but when she goes to the Brotherhood (bad mutants) her name is Phoenix. And she is a real Badass. Hence Phoenix's name. Such a bad little cat. I always say... what she lacks in size she makes up for in attitude
