Background

Qi Feng is a transmigrator from a parallel world and the only transmigrator known in that world. Unlike Yang Xiao, he possesses a system that provides access to resources such as Quirk Enhancement Pills and reagents. His early advantages and accumulated strength place him far above most Hero Class A students. 201 203

While attending U.A. as a Hero Class A student, Qi Feng notices Yang Xiao following him after school. Yang Xiao identifies him as someone who does not belong in that world, prompting Qi Feng to attack immediately. Their battle reveals that both possess Dual Quirks; after recognizing their shared circumstances, they end the fight and become allies. 201 202

Qi Feng follows Yang Xiao through the Egyptian Pyramid passage into Yang Xiao's world. The two discover that time flows unevenly between their worlds: nearly ten days in Qi Feng's world correspond to only a few hours in Yang Xiao's. 206 207

Appearance

Qi Feng is a black-haired young man approximately 1.78 meters tall. 201

• Uses a blue mask marked with a lightning-like pattern while competing in the Underground City. 208
• Wears Akatsuki-style clothing during Underground City matches. 208
• Takes the codename Thor to match his lightning-based power. 208

Personality

Qi Feng is highly confident and initially dismissive of his peers, considering most of them beneath his notice. He is quick to attack when he believes his secrets are threatened, as shown by his first confrontation with Yang Xiao. 201

Despite this arrogance, he is observant, pragmatic, and willing to negotiate mutually beneficial arrangements. He does not offer valuable resources for free to someone he barely knows, but becomes notably generous once trust is established with Yang Xiao. 205 214 241

Qi Feng is fiercely loyal to those he accepts as friends. He remains behind to hold off the Supreme, suffering severe injuries so Yang Xiao can finish absorbing the Immortal Water rather than abandoning him. 326 327

Abilities & Skills

Qi Feng's primary Quirk allows him to generate and manipulate powerful lightning for direct offense and large-area attacks.

Story Role / Major Arcs

Meeting Yang Xiao

Qi Feng's identity as an anomalously powerful Hero Class A student draws Yang Xiao's attention. Their hostile first meeting becomes an exchange of information about parallel worlds, power systems, and their shared status as transmigrators. 201 202 203

Underground City Debut

Using the identity Thor, Qi Feng rapidly reaches Gold Rank and teams with Payne in Gold Rank death-promotion matches. He becomes feared after helping repel and slaughter a force of more than fifty contestants. 208 210 213 214

Washington Gambling Arc

Qi Feng proposes using gambling to fund their growth, then dominates the Washington Underground Hero Arena through Spiritual Sense. His victories provoke the Card King, whom he subsequently humiliates and extorts alongside Yang Xiao. 232 234 236 240

Serum Advancement and Agency

After purchasing 500 W-type serums, Qi Feng advances to LV6 and later reaches LV7. He operates an agency in the Island Nation while continuing to pursue higher Quirk levels. 241 242 280 281

Giant World and Immortal Water

Qi Feng and Yang Xiao absorb the Supreme's Immortal Water, greatly raising their strength. Qi Feng battles the Supreme alone to protect Yang Xiao's final breakthrough, then recovers after Yang Xiao reaches LV10. 323 326 327

Separation During the Darkest Era

When the space-time passage becomes unstable, Qi Feng returns to his own world. He and Yang Xiao acknowledge that they may not meet again. 330

Trivia
