(Experimental concept here)
Full Name: Baphomet
Age: Unknown
Race: Formerly Infecta, now unknown
Gender: Male
Affiliation: Who/What do you fight for?: Tainted
Blood type: AB-
Crystal(s): Poison
Gear: Baphomet has powerful armor, fused and twisted to him by the taint. Large clawed hands and feet allow him to climb many vertical surfaces, while the armor itself provides him with powerful regenerative abilities.
His sword has also been corrupted by Taint, and it's swings can bring infection or deadly poison if Baphomet wills it, and slamming it into the ground can cause a fissure of the poison to rise up. Even without the poison or infection, the blade is deadly sharp, with a serrated and jagged edge. Lastly, he can further mutate and control Tainted around him, making them bigger, faster, and stronger, and an example would be his large Tainted pet, Merihem.
Appearance:

And for Merihem.

Personality: The Taint twisted his mind. He thinks of the Taint as ascension to a higher level, and that people are just too afraid and ignorant of the Taint to be taken. He tries to prove them wrong through force.
History: Baphomet was originally an Infecta, and was a brilliant scientist and doctor, and though he was a bit eccentric, he was certainly effective. He went aboard the Infecta ship and when he stepped off onto the jungle planet, he loved it. So much new wildlife to study, many new plants. He went out on the day the Taint missle hit, and was never seen again. It turned out he was near the epicenter of the missile's impact.
His body was corrupted, his mind warped, and new convictions formed. He saw it as an improvement. The taint mixed with the virus made him ever stronger, and able to last far longer with the virus due to it's regenerative abilities. He had found the answer to the Infecta's problem. But they rejected him, opening fire as soon as he came across a Infecta squad. That's when he grew angry. He killed them, exposing their bodies to the Taint. If the Infecta would not accept him, if Ragnarok would not accept him, then he would show them all where they got it wrong. He would show them the light.
He would show them their true destiny.
