In the last battle of One Punch Man season 2 Garou’s hair and one eye suddenly turns red. How did that happen? did he just transform or anything? many questions might be in your mind.
Garou, first fights against Watchdog Man. His relentless attacks make Garou severely beaten. After that, Garou crosses paths with Saitama. Even though he doesn’t recognize Saitama’s true strength, he attacks King. But then he receives a devastating kick from Saitama that significantly weakens him. His physical condition gets bad.
As Garou tries to recover, a whole bunch of A-Class heroes attack Garou all at once. Even though he is injured and fatigued, Garou fights back, but the sheer number of opponents and the intensity of the battle push him closer to his limits. During this skirmish, Garou is struck by two poisoned arrows in the right shoulder. But still, he defeats the A-Class heroes.
Next, Garou has to fight Genos, who is a very strong robot hero. This fight is really, really tough on Garou’s body. He’s already hurt from all the other fights, and now he’s pushing himself way too hard.
It’s during the fight with Genos that we start to see Garou change. His right eye gets very red because he’s straining so much. He’s also bleeding a lot, and this blood makes his hair look red.
But that’s not enough. His sensei, bang and bang’s brother Bomb shows up. Garou is well beyond his limits as he’s starting to have trouble seeing. But still he was fighting.
Conclusion
So, it’s not that Garou suddenly changed because he transformed or anything. His red hair and eye are the result of all the damage from his fights and how hard he’s pushing his body. Also, don’t forget he was poisoned on the right side with 2 arrows, and his right eye turned red. The red hair and red eye show us just how much Garou’s body has been through.
He is really something else. He’ll push himself to get what he wants, even when things look really bad for him. He fights with 3 S-rank (Watchdog Man, Genos, Silver Fang) and a bunch of A-rank heroes; He doesn’t even get a chance to break. But Still standing and fighting with them. That’s what makes him such a badass character that people remember.
