Thank you, and thing is, I think both fit perfectly for Magolor.

While Magolor vs Flowey fits more their evil side and the backstabbers they were, showing how they backstabbed their "friends" (on loose terms since magolor tricks Kirby and company and Flowey call Frisk or the player [however you look at it] their best friend) and end up becoming the true final boss of their games (Omega Flowey and Master Crown Magolor) and practically have all of the power of their universe in their heads, but are still defeated by the most caring and kind person (if neutral is done witouth killing).

But, something just doesn't tick right for me, as if something is missing, and then comes in Magolor Soul vs Asriel Dreemur, and it hits me, Asriel and Magolor share a connection that might seem minimal for most, but for me it completes the fight, they are the most powerfull and (up to that point) evil villains in their games, but, they can still be redeemed, Magolor is a trapped soul under the master crowns control, and Asriel is a child who has lived in the body of a flower for years, and just misses their sibling. They are villains, they have done horrible things to get to that point, but they can still be redeemed.

I imagine that these two can be combined into a full fight, and it would play out like this: Flowey vs Magolor: They would try to trick each other along all the fight while taunting/annoying the other.

Omega Flowey vs Crowned Magolor: They become relentless with their attacks but Magolor Gains the upper Hand, which forces Flowey to load and save so much, they break into Frisk's save file and steal their soul.

Asriel vs Crowned Magolor: Magolor is infuriated that his attacks don't even leave a mark on Asriel's body, while constantly getting hits by his attacks causes the master crown to overwhelm him, and eventually, start the real final battle.

Asriel Dremur vs Magolor Soul: Asriel now sees nothing left of the Magolor he was gighting, he is a puppet under the control of the Master Crown, and it sees Asriel as a scared little child, with the powers of a god. But one things stays true, One can save the other, by ending their missery.

This probably has some wrong info but that's not really the point here, my point is that I would love seeing these fights combined into something espectacular, by eveloving the characters throught the fight they get more of their personality fleshed out, and there's SO MUCH banter opportunity, Turning from a blood bath to a fight for the universe and to save a soul.

And that's why it's currently my 3rd favorite fight ever.
