American comics: I gradually replicate everything

Fan Ken wakes up to find himself transported to the DC universe, becoming Batman's junior disciple at Wudang Mountain during his travels to learn martial arts. On Wudang Mountain, his talent is mediocre, never earning his master's approval. But Fan Ken isn't panicked; fortunately, he can travel to other American comic book worlds. In the Boys universe, a single injection of Compound V awakens his superpowers—whether it's martial arts, qigong, or magic, anything others have mastered through learning, decades of hard work, or centuries of accumulation, he can replicate with a single glance. Skills others spend a lifetime honing can be effortlessly mastered with a single glance. Talents others are proud of are nothing but a joke in his eyes. In the Kung Fu Panda universe, he practices qigong, becoming the Dragon Warrior, even Master Oogway marvels at his martial arts talent. In the Avatar: The Ultimate Power universe, he observes the four elemental powers, mastering the mysteries of air, water, earth, and fire; the Avatar's millennia of accumulation and understanding can be learned in a single day. In the world of Jackie Chan Adventures, he seized the twelve talismans and learned all the magic of the Archmage Lopez, including the powerful spell that could forcibly extract the innate divine power of the Fire Demon Saint Lord into the twelve talismans. In the world of Invincible Young Hero... in the DC world... the knowledge and power of countless worlds converged in him, and he, with a mortal body, stood above the gods.
