Each has his own strengths. If you can kill them all, it will be Batman, because the master has all the information of superheroes, including weaknesses. Coupled with the master's mind and high technology, it is invincible. The weakest words, I'm not sure. If you insist, it's Batman, because apart from high technology and brain damage, there is no superpower, and a clean one-on-one fight will definitely kill you. Therefore, if a master wants to win the championship, he must have the right time and place.
