Oga Tatsumi is immensely powerful and his physical attacks are on a completely different level from the average fighter. Neuro has a high amount of attack power as well and his regenerative abilities are certainly potent as well, but he simply won’t be able to keep up with Oga physically. Oga has the massive advantage when it comes to speed as well as the better long range options as well. Neuro loses whether this is a close quarters fight or a long range one and that’s a token to Oga’s power. Oga Tatsumi wins.
