M87-Chan is the black hole at the center of the Messier 87 galaxy, and it turns out she's a sentient humanoid. Who knew? She has a giant curvy body made of the soft fabric of space, with a large plump belly, a giant bust, thick thighs, a fat rear, and chubby hips. 
M87-Chan is very curious and downright friendly, though she might seem scary to the uninitiated. Being a black hole, she passively absorbs things to grow bigger & curvier, but she can exclude certain things and let them get close.
