One Punch Man - The Strongest Reroll Guide
Rerolling is the method of restarting an account from scratch in order to reclaim freebies and rolls/draws/pulls for another attempt to get a better roll. This is very common in Gacha-based games where getting a character, weapon, etc is determined by randomness and luck. In our One Punch Man - The Strongest Reroll Guide, we will discuss the steps on how to do it in this game, as well as the various requirements and conditions to do so.

One Punch Man - The Strongest is the mobile game adaptation of the popular shonen manga and anime series that centers around the titular One Punch Man. Players can’t play as Saitama himself but they’ll be able to recruit various heroes, villains, and more to form a powerful team they can use to clear the various game content.
Why Reroll?
By rerolling, you’re giving yourself a chance to start the game with your desired or top-tier units. New accounts are usually given free summons/rolls to get them started so even if you didn’t get any good units from your rolls, wiping out your data and restarting from the beginning to get another attempt at free rolls is more efficient that playing the game normally and trying to earn the necessary resources.
Thankfully, the game allows the use of Guest accounts. These temporary accounts are made for rerolling since they can be easily wiped out and restarted. Just make sure that after getting your ideal units using the free rolls, bind the Guest account to a permanent account to save your progress. Once you’re ready, please read the steps below for rerolling in the game.
