“I Don’t Need Pretend Friends,” it’s the song that played while fighting Stain. Track 6 on the soundtrack for season 2.
Edit: I read the descriptions, and Todoroki vs Bakugo obstacle race is actually season 2 ep 2-3. I don’t remember that ost, so someone else can help. Fix your description too.
So i listened to all 140 themes of DBS and found nothing then my small brain finally decided to use shazam and found the theme its the theme of super saiyan 3 and the reason i couldn't find it is becouse it is originating from dragon ball kai.
Hope you enjoy the theme
