SOUTH DETROIT, 18:00

The two Bio-Sentinels stood at the heart of the inferno, scanning the area, searching for an energy reading.

Twenty short minutes ago, the place had been a bustling casino. The room had been full of people, full of Mutants. None had even noticed the sentinels arrive.

A fact they quickly exploited.

Now the room was ablaze, and the bodies of the people inside when the sentinels struck, no more than ashes. No bodies, no evidence, no pointers for the ever more mutant friendly police. A clean job.

Suddenly, one of the two sentinels was engulfed in a blast of yellow energy. The blast stopped and the sentinel was no more than a pile of disintegrating goo. The other turned to see a young mutant, well-built with spiky black hair. Yellow steam gushed from his outstretched hand.

The remaining sentinel opened fire, sending blast after blast of laser energy at the mutant. The blasts struck their target, but carried on going through him without causing any physical damage. The sentinel stopped to re-asses the situation.

The mutant's hands began to glow with yellow energy.

18:09

The mutant stumbled out of the casino, blood streaming from cuts on his arms, chest and left leg. His legs failed him and he fell, unconscious on the floor.

No-one noticed the black copter with a gold 'X' land nearby..
