The 12th born of the Bellows Brothers and protagonist. Very childish, energetic, and a D&D fan who loves to hang out with others. Although he mostly loses, he's a good sportsman at heart, showing that he's kind-hearted. After the event of Tem disappearing due to bullying, neglection from his brothers, and being humiliated by anyone be it innocent or brutal, joining the Future Foundation and giving him a more masculine physique, then finally returning home in his current timeline with a heartwarming reunion, Tem has become a bit matured but still has that inner childlike nature, showing that he can be a bit naive from time to time. His return brought back the brothers sibling group together again. Tem also got recruited to the Hellfire Club at Hawkins High School by Eddie Munson, teaching him the game and leveling up his character. Tem has some adventures of his own in his current age, such as helping out his father and King Orita, Savannah's roommate, by traveling to the Further and guiding them back into their bodies, journeying with his favorite idol explorer and his screaming, complaining, and panicking singer, and escaping murderous dinosaurs on the loose with his favorite author/archeologist. While he no longer wields Psychokinesis, he does awaken a new power known as Illuminum Physiology: the ability to have one's body illuminate bright light. He was nicknamed Lightbug, which he accepts as his heroic name.
Illuminum Physiological Applications:
Illuminating Body: Can emit bright light from his body.
Illuminating Invisibility: Can become invisible if another light and his body light makes contact with one another.
