Chris Bradley was leading a normal life, until one day when he started to get headaches (a result of his mutant power emerging). An electrical outburst from Chris destroyed all the circuits in his house, which led his mother to keep him home from school. The next day, two strange people started following him, and even parked outside his house after school. Chris got up the courage to ask out Donna Funaro, a girl he had a crush on.
During the first period that day, sparks started shooting out from Chris's fingers. He managed to escape to the bathroom, but the sensation got worse and Chris started shooting out enough electricity that it was shooting through the whole school. The two people who had been following him turned out to be Gambit and Phoenix of the X-Men, who took him home to explain to his parents. Chris overheard them and ran out of the house in panic. He went to see his friend Jeff for support, but Jeff freaked out and rejected him since he was a mutant. Chris eventually calmed down enough to visit Professor X. Chris's parents agreed to enroll him in the Institute for observation and training, since he left a good impression on them.

Leaving the School
Chris thrived at the school, until it was discovered that he had contracted the Legacy Virus. He went back home, and found out that Donna still wanted him, even though he was a mutant and had the virus. The X-Men fell out contact with Chris, due to events like Onslaught and the assassination of Graydon Creed.
Chris's parents tried to find ways to cure the Legacy Virus, but at a clinic where they were willing to treat it, Chris had a run-in with the Friends of Humanity, and was saved by Maverick. Maverick told Chris how to find him if he ever was needed, and when his home was burnt to the ground, Chris suspected the Friends were behind it, so sought out Maverick to help him get back at them. Unfortunately, he led the Friends right to Maverick. The two managed to defeat them with the help of Wolverine and Iceman.
After facing the Friends of Humanity, Chris made arrangements for Chris and his family to move to Florida and become the "Johnsons". Things went well in Florida until the Legacy Virus began to cause Chris to lose control of his powers.
Chris ran away, back to New York, where he once again became a target of the Friends of Humanity. Wolverine, Maverick, and Elena Ivanova came to his aid, and the four barely managed to escape in the midst of an explosion. Maverick told Chris it was time to pick a codename, and so Bolt was born. After that, Chris tried to find himself an identity as a superhero. This came in the form of the young teenage superhero team known as the New Warriors. Chris fought some battles with the team and was a valuable asset to them. However, soon events would arise that would change Chris' life forever.
Vengeance as Maverick
After the believed death of Maverick at the hands of Sabretooth, Chris swore that he would get revenge for his old friend. He tracked down the mutant Cable in the hopes of receiving combat training. Cable trained him, and Chris took on the look, sound, and even attitude of Maverick. When he was ready, Chris left Cable's tutelage, and ended up joining Marrow's Gene Nation in the hopes of taking them apart from the inside.
For his first mission, Chris was sent to aid a terrorist attack on Grand Central Station. While he was attempting to stop the bomber, Chris was confronted by Agent Zero, who believed he was the terrorist. The two battled, and Chris was mortally wounded. He died without knowing the true identity of Agent Zero.
Chris has been resurrected by Eli Bard's Techno-Organic virus to become one of Selene's deceased mutant army to attack Utopia.
