Tag Harris is a teenager from Smallville, Kansas who was given superpowers by exposure to X-Kryptonite.

Tag was a student at Smallville High School and the star wide receiver of the Smallville Crows. The first week of school he attended a keg party at the Shuster mines where the bonfire mysteriously exploded. He was injured in the blast, suffering a broken arm that would likely cause him to miss the entire season.[1] Unbeknowst to anyone at the time, he was exposed to trace amounts of X-Kryptonite, triggering his development of metahuman powers.[2]

Although he could not play, Tag was required to attend football practice and games and watch from the sidelines. He became friendly with the Crows’ backup quarterback Jon Kent, who also spent most of his time on the bench. After the first game of the season his broken arm began spasming uncontrollably at superspeed.

At practice the next day the coach criticised Tag for getting hurt before the season and he stormed off to the bathroom. His arm spasmed hard enough to shatter his cast and he found that his arm was miraculously healed. At a team party that night Tag’s spasms worsened and he fled into the woods. Jon and his brother Jordan followed him and found Tag uncontrollably moving at superspeed wracked with pain. Jordan attempted to restrain Tag but was thrown away. Jonathan summoned their father Superman, who flew Tag up into the upper atmosphere where the thin air caused him to pass out. He was taken to a school for metahuman children run by the Department of Defence.[2]

Tag returned to Smallville, now wearing a uniform of some kind and seemingly more in control of his powers, and attacked Jordan on a highway, blaming him for his condition.[3]



  • Power Instability: Tag initially could not control his powers, which appeared to cause him considerable pain.[2] After some training he appears to have better control.[3]
