Kefka vs Goku

[Lazerface]

But knowing Goku wouldn't know the FF verse's stats and items too well hr might come a bit unprepared except for bringing his clothes on his back and his power and intellect (if it's that big). I think your scenario might be true since the rules of the FFverse don't apply to DBverse. But I remember one guy saying on DBZ forums that if Babidi the wizard who revived Buu was a fighter with the magic he was able to use, he'd probably the deadliest enemy they ever fought. Buu was something but his magic knowledge was limited to turning people into candy. Babidi had a far larger variety of magic attacks. So I guess a Babidi fighter would be a bit like Kefka in some ways.

Magic has always proven to be a 50:50 thing in Dragon Ball. Sometimes you resist, sometimes you don't. Also magic can be deflected. Boo counters the transformation magic, Vegeto is totally immune against being negatively affected by it as his candy form makes no difference for him, Babidi's mind control magic is useless for Vegeta as he is corrupted and stronger with it but does not follow Babidi's orders, et cetera. So basically it is all about the "if you are stronger than that you can resist it" again. And Dragon Ball characters are very resilient to magic that they do not want to negatively affect them. You would need someone who actually is shown to have really overwhelming power while wielding magic. Something Kefka was not shown to have. He devastated the landscape and made it infertile. Piccolo Daimaoh was able to use such destructive power already. Kefka's power is not fleshed out enough. Oh - and Boo is not limited to just making sweets.

You need to have power that is really shown to be overwhelming.

If we take X-Death for example he would be totally useless against Goku. The Void is not just shown like some space-time-less "thing" but also shown like a prison from which you can break out. Right before the final battle they do. And that makes the Void already another dimension even though it shouldn't be. Goku can break out of other dimensions. Boo and Gotenks also did. As a matter of fact Goku, Boo, Cell and others have even teleported between dimensions.

EDIT: Yes, I did draw it. Thank you.

Hmm. Makes sense but I have to ask. Which FF villain would have magic power that is straight up overwhelming? Next on the list I could say Ultimecia, Cloud of Darkness, and Zeromus. But I will say, Ki attacks can be deflected too. I've read that prominent Ki users don't exactly have good resistance against Magic kinda like Superman. But if what you say is true and being turned into candy doesn't affect someone like Vegito then you'd have to try something a little less comedic and a little more...upscaled. A attack like Big Bang, Particle beam, Ultima, Supernova (less of a illusion and more actual that destroys the solar system, and Flare. Kefka has a small advantage of being able to attack before Goku could get anywhere by simply calling out Forsaken and Goku wouldn't exactly see it coming since it'd come from everywhere. But if he knows Magic well enough to resist it or at least avoid it he'd have an advantage. SO I guess we can say that Transformation magic and mind control magic should be thrown out as it doesn't exactly apply here. Purely offensive and defensive and medical magic would apply here in Kefka's case. I say so because transformation and mind control can be resisted or may not affect the affected. I think Kefka has the advantage of range as well, then again Goku does too if he's using Spirit Bomb, Kamehameha, or Destructo disk. I read a few fanfics in which Dante from DMC (not the crappy reboot but the original) fought Goku and the much was a draw but it said that if it was a fight to the death Dante would more than likely win because of his regeneration, magic abilities, and Devil Trigger. Goku fought at SSG here but I thought it was alright and would hint the Magic>Ki barrier. Strange thing, Dante recognized he used Ki so I guess Dante's smarter than Goku?
