The Beast

The Beginning
The Beast was formed at the dawn of the multiverse. He was created to be a living embodiment of evil. The Beast brought destruction to various worlds, and then found The Nexus by mistake. The Beast, realizing destroying the Nexus would be great for evil, he set forth. He ravaged a whole continent, until the mightiest wizards of the age cast a spell, flooding the whole continent. As the beast was made of living magma and rock, water imprisoned the beast.

Escape
The beast was sealed in a mighty, cage. A spell was cast over the cage to be indestructible. The beast was located in an underwater cavern. After millions of years, the spell weakened. At the same time, Maxios Baxterofski, a new member of HALO, being passing out mysteriously and feeling cold when no one else did. He was drawn to the libary inside HALO, where using a chair, he made a good sized hole in the floor. In the hole was a ladder. When he went down a ladder, he discovered The Beast. He fled, and came back with other HALO members. The Beast, using his magma sword, cut through the bars of the cage, and got loose.

The Defeat
Battle was raged across HALO base, leaving the libary, kitchen, and varoius hallways in ruins. Maxios, with the help of a wizard who as part of HALO, sent the beast into the ocean, once again trapping it. Maxios was grabbed by the beast, and dragged to the bottom of the ocean (Maxios was promptly resurrected). Maxios, knowing that the embodiment of evil couldn't have been beaten so easily, has a feeling we haven't seen the last of the Beast...

He was right
Maxios' Evil Clone became the Hand of the Beast. He proceeded to bring back the Beast, who tried to have vengeance on HALO. He was captured, and had a Maid's Uniform put on that made it impossible for the Beast to purposly attacking anyone.

Maxios vs. Mercury, Round Two
During Maxios' battle with the mad mage Mercury, a hologram of Maxios made peace with the Beast. In exchange for letting The Beast return to his plane of existence, Maxios could summon him at any time for help. The Beast proceeded to storm Mercury's manor, before being easily defeated by...a water elemental. After the battle, the Beast returned to his domain
