Tag became a football player for Smallville High School who specialized in receiving. Though his family was among the poorer people of Smallville, Tag made many friends and was invited to a bonfire gathering held by the students.
The next day, during football training, Tag asked Jonathan if the new player on the field was his brother Jordan.
Tag started vibrating at different times causing Jonathan to worry. One of those vibrations was strong enough to break Tag's cast. During a party at Corey Wellnitz' lake house to celebrate the football team's latest victory, Tag's vibrations got worse. Jonathan and Jordan followed him into the woods and found him vibrating out of control. Using the ELT device that their dad gave them, Jonathan started calling him. After swiftly defeating Thaddeus Killgrave and the Intergang members present, Superman picked up Tag and took him high enough in the atmosphere to stop the vibrations by depriving him of oxygen. Sam Lane later mentioned that Tag is in the custody of the DoD and suspects that the heat vision that Jordan unleashed during the altercation set off a nearby yellow phosphorescence. He also mentioned that he will be transferred to a special school for people like him.
Tag later ambushed Jordan as he was walking home from the Smallville Harvest Festival and demanded to know what he did to him. Jordan used his signal device to call Superman, which caused Tag to flee, but was unable to capture him due to Tag using his speed to derail a train, forcing Superman to stop and fix it. Tag went to Sarah's house to talk to her, but he lost control of his powers and knocked her unconscious. Then he carried her to his hiding place in Metropolis and told her what he thought had happened during the explosion at the shuster mines; that Jordan was responsible. Eventually, Tag was found by Superman and General Lane's soldiers. They shot Tag, Superman blocked the bullets, being wounded by a kryptonite bullet in the process, and angry, he ordered them to stop. Tag was recaptured and returned to the premises.
Tag is shown to join others to attack others.
Powers and abilities
- Meta-human physiology: Due to the exposure to the yellow phosphorescence, Tag's DNA was altered, turning him into a meta-human.
- Bodily vibration/Super strength: Due to the exposure to the yellow phosphorescence that was unleashed the day when Jordan Kent's heat vision manifested, Tag started to develop vibrating powers with one vibration being strong enough to break his cast, a table corner off and punch through a tree.
- Superhuman speed: While vibrating, Tag can run at superhuman speed. According to Sam Lane, Tag's new-found speed rivals that of Superman, placing him above Supergirl and below the Reverse-Flash.
- Accelerated healing factor: Tag's broken arm healed faster than normal.
