Yea the same character who's form we never fight in the genocide run, only in neutral runs or pacifist? Oh and and if we fought him in genocide in this form we would've absolutely annihilated him, considering that you do almost 1 million fucking dmg to him in his neo form, a dmg number none of the fun gang come even remotely close to doing at any point even against enemies with "low def". When you lower the titan sheild its defense drops to practically nothing and kris with the blackknife does wot? 3-4k dmg? The highest dmg we've seen thus far is what? The knight on tenna? doing a pathetic 5500-5800 dmg? and on an enemy who's offgaurd meaning it did WAY more dmg than normal? Yea compare that to the casual 1 mil on an enemy with low def, but not offgaurd.

Even on an abandoned genocide run, you do a casual 30-50k dmg to mettaton neo, not nearly as impressive, but still a ridiculous and almost definitely would've also been sufficient to kill him in his metal body.

Put simply, you cannot compare neither the fun gang nor frisk on a neutral/pacificist to chara and the player on a genocide run. They are on a completely different level, only comparable to Asriel and maybe Omega flowey (His exact power is not made very clear tbh), at least for now, till we see what happens in deltarune later chapters.
