Appearance
Tetsutetsu has hardened-like hair, around his eyes he has metal-like eyebrows and razor sharp teeth.

Personality
Tetsutetsu has a tendency to act hot headed and lets his emotions get the better of him. Though he also isn't stubborn to cheer for a rival, as he did so in Eijirou match with Katsuki.

Sports Festival Arc
Tetsutetsu is seen outside Class 1-A and says that he heard about them defeating villains and wanted to hear it directly for himself but not from Katsuki who he calls a snot nosed punk. He then yells that they better not embarrass them at the main event, which frightens Izuku, Tenya and Ochako.

After Katsuki makes his declaration to place first, Tetsutetsu is angered by Katsuki's overconfidence and says that he will crush him. During the Obstacle Race after Shouto causes the huge robots to tumble over with his Quirk, Tetsutetsu is buried alive by the robots, but Tetsutetsu uses his Quirk to survive and dig himself out, saying that Class 1-A are a bunch of obnoxious brats. He eventually finishes the Obstacle Race and places 10th, allowing him to participate in the next event, the Human Cavalry Battle. He later teams up with Juuzou, Ibara and Yousetsu.

Before the Human Cavalry Battle begins, Neito says to him that they should participate with no hard feelings towards each other, which Tetsutetsu agrees with. At the beginning of the event, Tetsutetsu's team attacks Izuku's team with Juuzou using his Quirk to trap them, but Izuku uses his jetpack to escape. Tetsutetsu's team attacks them again, but Fumikage's Dark Shadow blocks them off. Tetsutetsu manages to evade Tsuyu's long tongue attack. After the Human Cavalry Battle ends, Tetsutetsu's team fails to qualify for the final event with Tetsutetsu confused as to how they lost all their points, with Ibara remarking that it is possibly punishment for taking the dwarfy kid's headband in such an unfair way.

After Mashirao and Shouda resign from the tournament event, Midnight says that the empty slots will be replaced by Team Kendou, but Team Kendou gives the opportunity to Team Tetsutetsu, much to Tetsutetsu's happiness. Therefore, Tetsutetsu and Ibara become part of the Top 16 in the tournament event and he is paired against Eijirou Kirishima in the first round.

Tetsutetsu faces Eijirou in his first round match. However, Tetsutetsu fist fights Eijirou to a draw, causing them to participate in an arm wrestling game to determine who will advance to the next round. After Katsuki defeats Ochako, Tetsutetsu faces Eijirou in their arm wrestling game to decide the tiebreaker. Tetsutetsu is defeated by Eijirou, which eliminates Tetsutetsu from the tournament. Afterwards, Eijirou comments to Tetsutetsu that it was a fine match.

During the match between Eijirou and Katsuki, Tetsutetsu roots for Eijirou, telling him to hit Katsuki's jaw. After Katsuki defeats Eijirou, Tetsutetsu boos at Katsuki. After the match between Fumikage and Katsuki ends, Tetsutetsu notes that Class 1-A are hogging all the glory.

Tetsutetsu along with his class watches the closing ceremony of Yuuei's Sports Festival.
