Asteroth

The Asteroth is a ancient, demonic weapon with the power to take on any form its wielder wishes. Hellbane owned the Asteroth originally, but later gifted it to his oldest son Donny, in whom's hand the Asteroth took on the form of a red, axe-shaped E-Guitar.

Even so taking on a permanent default form most fitting to its wielder, the Asteroth is still able to rapidly shapeshift to suit the current needs of it's owner. So far it grew monstrous spiderlegs to carry Donny and Serge up a tower, sprout giant dragon wings and transformed into a shield.
