Title Demon of the Night
Status Alive

Demon (full name: Demon Mortem Negative) is Darkusinfinity99's Darkus Spatterix, and his second guardian Bakugan. His Mechtogan is Shadow.


Demon is a Spatterix that loves to fight. He can deliver harsh blows and moves so quick he sometimes dissapears. He loves to confuse his enemies and attack them when they least expect it. He can fly to very high altitudes and swoop down unexpectadly. He is a very strong leader. In both human and Bakugan form, Demon can control shadows, and disappear at will.


Demon can be sweet and gentle, but can also be demonic, as his name suggests. He is not afraid of anyone, and is only loyal to his Brawler.
