My longest-running character, Steel Wolf. Created back in the heady days of the Marvel RPG, despite the years he remains my favorite. And since Devcon's Zoot-Suit Riot layout was so cool, I'm going to go ahead and co-opt it here...

HISTORY: Alexi Krylenkov always dreamed of serving the Soviet People. As a result, when he became of age he enlisted in the military. Rising through the ranks, he learned of a project designed to reproduce the accident that created Russia's greatest hero of the second world war, Stalnoivolk (or "Steel Wolf"). Applying to this program alongside dozens of other candidates, Alexi was subjected to a battery of experimental procedures, exotic energy exposures, and other classified operations. Despite the high mortality rate, Alexi was one of a handful of individuals who survived the process and emerged with superhuman abilities. Given special training, Alexi was assigned to a small three-man unit with two other survivors code-named 'Red Trinity'.

Over the years, the powers of those involved in the process began to change and, in many cases, diverge from the original baseline they all possessed. Alexi's powers were one of the more extreme cases, making him among the most powerful operatives. Granted a new costume, and deployed as a solo operative, he became Russia's greatest hero, trusted by his military superiors, but beloved by the common man he protected.

When the United Nations proposed a new group of superhuman operatives answerable to the security council, The Russian Government assigned Alexi as their representative. At first untrusting and standoffish among his teammates, Alexi soon learned to value their opinions, and admire their courage and sense of duty. He also began to see that perhaps his single-mindedness in thinking his duty was first and foremost to the Rodina may be incorrect, and he should be more concerned with global threats. When he confronted his superiors about this, they ordered him to resign his position with the New Alliance and return home. Unwilling to allow the world to suffer because of his short-sighted superiors, Alexi refused. Now deemed a traitor by his former commanders, he became a fugitive, and sought asylum in the New Alliance's headquarters. After several unsuccessful attempts to return him to Russia, The Soviet government expatriated him completely. Regardless, Alexi continued to serve the Alliance, now having no other purpose or home in his life.

After many tumultuous years and the help of longtime teammate Auren, with whom he had become romantically involved, Alexi finally came to terms with his situation and new status, and became a citizen of the United States. Adopting a new costume, and continuing as an operative of the New Alliance, it was at this time that he met the group of heroes who would colloquially come to be known as the "Allspark Heroes".
Alexi has since assumed a new, more casual costume (as seen at the top).
POWERS/ABILITIES: Alexi possesses a wide array of physical abilities, including massive superhuman strength and durability, enhanced speed and senses, flight, as well as the ability to absorb most forms of energy directed at him and either convert it into further enhancing his physical powers or emitting it as energy blasts from either his eyes or hands. He also heals at an accelerated rate, and can survive for extended periods of time unprotected in a hard vacuum.
WEAKNESSES: Alexi must take great care when interacting with others, as his strength is so great he could easily harm others unknowingly. In addition, if he absorbs too much external energy, he can either cause himself harm, or lose control of it and cause an explosion of great magnitude.
PERSONALITY: Steel Wolf is a genuinely compassionate person who strongly believes in protecting those weaker than him. He can seem a little arrogant at times, but when you consider the fact that he is one of the most physically powerful men on the planet, this attitude seems somewhat justified. Although he is loyal to the Soviet government, his first duty is to the Soviet people. Alexi takes great pride in carrying on the name of his Golden Age predecessor, and always tries to bring it honor.
