This is the class B Berserker, it's like a puma or a panther. It's made for speed attacks and has blood lust to match it. These usually are about 5 feet high from shoulder to ground and about 1000 lbs. They're usually handled in groups of three by a Tamer who keeps them inline so they're bloodlust doesn't cause collateral damage. These things have great eyesight, hearing and smell unlike the C class. These will pursue targets until they're meat piles. The trade off is that they're not near as physically powerful as a C class.

These things reach adulthood in a year from birth. A possible Tamer is placed within a cell with three of them and isn't let out until he's beat them into submission or is killed. If he's killed, the berserkers are killed too since they now recognize the Mason army as no threat.

I'll post the colors tomorrow, when I finish them.

EDIT - Colored, on to the Tamer
