Suggested by Sonic Deku is the ultimate close quarters combat fighter in MHA to the point where I’d say he’s currently the strongest fighter alive in that verse. Still, Tatsumaki has had some incredible feats during her recent fights in OPM and should be able to cancel out his attacks with her own long range abilities. Tatsumaki is fast enough to stay out of range and pepper him with psychic blows. I see this being a close battle but Deku can’t break through her defenses. Tatsumaki wins.
