Tank
Tank was created when City of Villains was made.  I
needed a loyal stupid guy that would follow Photon
instructions to the letter.  Tank was born.

There is pretty much no changes to his powers from
his creation.  His looks also didn't change to much.  
He is still almost completely replaced with robotics.


A QUICK ORIGIN OF Tank

Sgt Grimes fought during the great invasion.  His
company was completely overrun by the Plants and
he was the only survivor.  When  he awoke in the
hospital he found out he had no arms or legs.  He
went into a depression.  Photon found out about Sgt
Grimes and offered him a chance to add purpose to
his life again.  Tank had 85% of his body replaced
with cybernetics.  

He is now Photon's muscle.  He has no problems
killing people to get an assignment done.  This is not
know if its due to his military upbringing or some
cybernetic enhancement that Photon installed.


Tank Powers

Tank possesses cybernetic enhancements that
provide superhuman strength, speed, endurance,
and durability. Tank can also interface with
computers.

His boots allow him to fly at subsonic speeds.  He can
communicate with Terra Corps satellites and have
instant communications with Photon, if needed.  He
has built in infrared and sound enhancers.

He carries a two specialized gun in his legs.  These
guns can be reconfigured while they are in his legs to
suit whatever need that Grimes might want.   The
guns he has produced so far are Assault Rifles,
grenade launchers, flame throwers, and sniper rifles.

He also wears a telepathy resistant helmet.  This
helmet has been known to mask his thoughts to
people with telepathy.  It reduces any mental powers
that effect Tanks mind.
