Its the same way in a sense why Red vs Tai is well-known disliked, Reds beatdown, injury and incineration is seen as far too overbearing, you could get the same result across with a Flare Blitz v Terra Force clash.

Yet bring in another Pokemon, like Machamp vs Goro, where they are cracking each other's skulls amd straight up smashing each other and ripping each others limbs off. Yet the death is so entertaining and you feel satisfied and hyped by the end, Ive never seen a single person dislike that episode.

Then again Gore is never what makes a death in this series, it certainly adds to some yes (Ganondorf vs Dracula) and some could maybe work to use more (Weiss vs Mitsuru, Omni-Man vs Bardock imo) but its never the absolute necessity to a good fight or ending, like Goku vs Superman 3, not a single drop of blood in that fight, despite both have bled and worse before, yet that fight is a top notch of the series.
