when ever im at my cousins house and they bring up Dbz I just let it happen, but when they're at my house and bring up Goku im like "What? KAKAROT!? F@CK OUT OF HERE WITH THAT SH!T, THIS IS SAITAMA TERRITORY!!"
In my opinion its too early to decide. Saitama's powers haven'tbbeen fleshed out enough. It would be like goku having his SSGSS form going up against that pterodactyl creature from EP.1. I believe we will be able to decide more definitively in the future
