There are over 16 characters currently in OPM One Hit One Kill, with plans to increase the roster considerably in future updates. We’ll update this guide with each character release and place them into our ranking system. 

What Our Tiers Mean

Here’s what our tiers mean.

S Tier List

The best characters in the game, and deemed the strongest when it comes to their abilities. We recommend trying to obtain an S-tier character as soon as possible.

A Tier List

Fantastic characters and great replacements if you don’t manage to get your hands on an S tier. They can be used alongside S-tier characters and can easily help you clear content.

B Tier List

Not the best in terms of strength but they’re good fillers at the start of the game. They can be used as a support choice to aid your A-tier and S-tier characters.

C Tier List

It’s best to avoid placing these characters in your party, especially if you want to clear content efficiently.

D Tier List

Not worth upgrading or using at all and should be avoided completely.
