Alexander Wahl was a member of the Shadow Army. He was arrested in 2001 on charges of assault with a deadly weapon. He spent 11 months in jail and when he was released his parole officer gave him a telephone number of a man who was looking for skilled criminal agents who might want to enter the "big time". Alex called and eveutally set up a meeting with Dr Bracke. The process that gave Alex his powers is a derivative of the process that created Giganto. In his Coldstone identity, Alex is hunted by Giganto and UNTIL. The Warlord was after Alex for not returning to the fold. Doc Despot purchased Alex's life and was allowed "custody" of him.
Coldstone enjoys being able to have the best of both worlds. He enjoys the power of being a rampaging elemental while still being able to operate as a normal man. For this fact he is very loyal to Dr. Bracke. He serves as the head of security for the team as well as its main muscle.
You have just run in to a Mountain of trouble my friend.
His martial arts training aside, Coldstone is a standard brick. He just trade punches with other bricks unless they prove capable of a) hurting him, and b) evading him. If this occurs he starts to fight a little smarter, blocking and attempting to grab.
A brick with some skill. If Coldstone is too powerful, and he is above the norm in strength, take away his martial arts training and lower his HTH levels to 4. If he isn't tough enough, raise his Dex, defenses, and spd accordingly. He should be a slow prodder though so don't go making him swift or anything.
Normally, Alex is a short, wirey man with brown hair and eyss. He has a soul patch and no moustache. He wears casual clothing and occasionally a side arm. As Coldstone he wears no costume but is a humanoid mass of dark stone with glowing, green, pupil-less eyes. Curiously enough, his stone appearance is different from Giganto's but the latter still knows the process was the same. It is unknown at this time why Coldstone is slightly weaker than his predecessor.
