While searching for stolen Stark Tech and destroying different terrorist organizations, Iron Man encountered Boris Bullski at an A.I.M. nuclear despot in Russia. Stark remarked the Bullski's suit was a second-rate knockoff of his. Bullski's suit was powered by nuclear energy, and when the two engaged in battle and Bullski was defeated by Stark when he cut off his supply of nuclear energy before he could recharge his suit.
The Titanium Man Armor used nuclear energy as its source of energy, making it very powerful.
The suit can create an energy shield around its wearer. However, this energy shield cannot protect them while the suit recharge. An overload of nuclear energy may cause a nuclear explosion.
It is not mentioned whether the suit has sufficient protection from the very nuclear radiation that emanates from it. This could mean that either Bullski is trapped in the suit, or A.I.M. has radicalized the suit to withstand immensely lethal radiation.
- In the PSP version of the game, the Titanium Man Armor can also be unlocked as an alternate costume for Iron Man.
