Lupus

When a star dies, it either becomes a white dwarf, explodes into a supernova, or... a third option. Lupus is that 'third option'- a demon born from a supernova that possesses human and animal traits. He's a wolf, of course. Usually, these demons have designated worlds they seek the destruction of. His little siblings, Gadrielle, Capras, and Cosmos, all have worlds- the Spoke and Wheel and Canvandro respectively. Lupus, their predecessor, has a world too, of course, but what it is? Well, that remains to be seen... Secret boss of Escape from Canvandro.
