I would be Calliope Fairchild AKA Callie. A 17 year old shapeshifter who has no real home. Moving around a lot and rarely staying anywhere for more then a year. When she meets the genderbender AT gang, she slowly warms up to them, thinking that maybe, just maybe she found some place she could finally call home. As luck would have it, there was a abandoned house half way between Marshall Lee's cave and Fionna and Cake's tree house. After fixing it up a bit Callie invites them all over for a house warming party, though she had only known them for a few days, Callie, Fionna and Cake were already rather close. Marshall Lee enjoyed playing pranks on her, replacing her shampoo with hair dye, making her go from a very pale blond, to a vivid blood red. When she knocked his door down and marched in, her hair flying around her and a snarl escaping her lips Marshall froze, his crimson eyes wide. The fire spilling from her electric green eyes, combined with the vividness of her blood red hair mad her look like a goddess of destruction and death. After screaming at him for an hour, Callie finally calmed down and listened to what he had to say, a blush forming on her pale face when he said that the color suited her and that she looked very beautiful. Since then Callie has formed a tiny crush on Marshall, though most of the time she wants to pummel him, her heartbeat still races when he smiles at her. Her favorite forms to take on are a silver wolf, a humming bird, butterfly, calico cat, and occasionally a small bat.
