Who can take Luffy's pain?
For those who don't know this is the scene in question where Zoro, Luffy's first mate takes on all of his pain so he can feel better. Through sheer willpower and some durability he seemed to be still standing.
Now I'm not sure if it would be more fair if some of these people were already hurt/injured like Zoro was or not so if it would be then I'll find a scenario when they were badly injured or just say they had Zoro's injuries.
1. Batman: If he needs to be injured/fatigued then we'll use him right before his fight with Bane in Knightfall
2. Spider-Man
3. Kratos with no God powers
4. Iron Fist with Zoro's injuries
5. Pre-Death Saiyan Saga Goku, if it would be more fair for him to be already injured then right after his victory over Vegeta.
6. Your pick of whoever you think can.
