Mark Smith was working as an apprentice electrician when he accidentally grounded himself to a live wire. The current involved should have been enough to kill him; instead, it triggered his anomalous powers. He found himself larger, stronger, and far more durable... and shortly after that, he discovered that he was charged with electricity, which he could use for ranged attacks. 

He did eventually get his license, and makes a decent living working as a licensed electrician. However, the money available working off the books as an "enhanced" bodyguard or leg-breaker eventually proved too tempting -- especially since he could look like an ordinary man right up until the time came to charge up his powers. He took up the name Storm Giant, and hunted around online until he found a specialized boutique that would provide clothing that could change size along with the person wearing it. 

At age 33, he is content to have most of his income tied to his regular job, and supplement it with the occasional special assignment. For those, he wears a special "ninja hood" of the same material as his clothes, and keeps a powerful, compact battery in his pocket to trigger his powers if another source of electricity isn't handy. He has never tested the full limits of his power; the more electricity he draws, the larger, stronger, and tougher he grows. If there's a limit to that, he hasn't found it yet -- but he's also aware that the bigger the giant, the more of a target it represents.
