Through enormous training and discipline, a One Punch Man can defeat any opponent with one blow. This doesn't help him one iota in shopping for groceries.
Level Progression as Fighter, but with the following class abilities.
ONE PUNCH
Your One Punch deals four* times your level damage, plus your strength mod (you should definitely write this number down somewhere). You can deliver One Punch every combat. If your One Punch misses, you did not actually punch anyone; instead, you spent the turn worrying about coupons.
*Assuming your monsters use d6's for their hit dice. If they use d8's, you deal five times your level.
CONSECUTIVE NORMAL PUNCHES
At level 3, you can split up the damage of your One Punch between multiple targets.
NOTHING BUT PUNCHES
Except for your One Punch, you cannot punch, kick, or deal damage with any hand held weapon.
HUMANS CAN'T FLY
At level 2, a One Punch Man can jump their level times 100 feet.
FUCK YOU BUILDING
At level 4, your One Punch deals quintuple damage against buildings, rocks, and other environmental structures. You only get One Punch against them.
EXTREME TRAINING
The secret to your One Punch is a (not that intense) training regime.
- One hundred push-ups!
- One hundred sit-ups!
- One hundred squats!
- A ten kilometer run!
- Three meals a day! Just a banana in the morning is fine.
- And never use the AC or Heat. It strengthens the mind.
If you follow this regime every single day for one month, you gain 1 point of Strength, Dexterity, or Constitution. For every point, there is a 1 in 20 chance you go bald. There is no limit to how many points you can gain like this.*
* FIIINE YOU WIMP OF A GM. There's no further benefit after three years.
Most episodes of one punch man boil down to this: Saitama can defeat anything in one punch. Therefore, most of the plot is all the stuff that happens before he shows up. I made this class to capture that feeling. You're the ultimate glory hog: your friends beat up the monster, and then you effortlessly finish it. Feel free to replace the punch with a sword: chopping through entire buildings is pretty anime too.
Is this class even remotely fair? No, not really. And that goes both directions: after you kill one guy, you have nothing to do. If all of this makes your character seem too useless, you can add this ability. It would probably take more than this to fix the class though.
SWEET THROWS
At level 2, you can throw an opponent. Regardless of size. This deals 1d4, and they need to make a CON check. Failure means your friends get advantage to hit them next round.
