....Dude. That's not how it works.
For one, Dharkon's never shown to do that. Unless it's just your head canon, in which I'm not listening.
Also, using actual feats, Shaggy AP stomps.
Dharkon should scale to Galeem, who is able to use many Master Hands as weapons. Master Hand made Smash, which consists of infinite possibilities. That's a bit above baseline, but not by much.
Shaggy upscales from Thanos, who is able to wipe out multiple Celestials, who are each 2-A. What's even crazier is that, IIRC, each infinity stone holds an infinite multiverse. Lastly, if we use all this scaling, Thanos has scaling that puts him infinitely above baseline 2-A. Shaggy upscales. Pile that up with the fact that IG Thanos has High 2-A feats...
Oof
The sheer downplay here is blowing my mind.
Within the Super Smash Bros macrocosm,
infinite timelines/universes are infinitely created with every single action and inaction. Master Hand is the creator of Smash and
fictionally transcends it, viewing the inhabitants of the macrocosm as nothing more than plush toys and trophies. Furthermore, there exists a dimension transcendent to Smash referred to as
the "Real World" which is explicitly mentioned as far back as
Melee and
Brawl, and is also explicitly referred to as the world beyond Smash in Brawl, with Master Hand as the link between the two worlds twice in both the aforementioned games. Within said cosmology explanation above narrated by Sakurai himself, Master Hand and the ending of Classic Mode are shown at the same time Sakurai mentions the Real World, effectively removing any form of subtlety about Master Hand's role at all. Both of those combined with Master Hand's fictional transcendence over 4-D Smash, the existence of the "Real World" possibly being Master Hand's realm further supports Master Hand being a 5-Dimensional Being with 5-D might. Even if you want to argue against that, within said cosmology explanation above narrated by Sakurai himself,
Master Hand and the ending of Classic Mode are shown at the same time Sakurai mentions the Real World, effectively removing any form of subtlety about Master Hand's role at all.
It's stated that the fighters are actively trying to "become real" and are viewed as toys in the real world. With this we can come to the conclusion that Master Hand essentially turned the characters into fiction.
Scaling all those feats up, Dharkon, if wanked and equal to Galeem, should be High 2-A or even Low 1-C due to reducing to a spirit/fiction Tabuu, who overpowered and puppeteered Master Hand, who already transcended a 4-D verse with infinitely infinite worlds.
Thanos, on the other hand... just can't compete.
Destroying multiple Celestials isn't all that impressive, as far weaker beings than 2-A Thanos, like the 2-C Destroyer,
have been able to harm Celestials, and the way you worded "who is able to wipe out multiple Celestials, who are each 2-A." made it seem like a physical destruction to me, and thus really basic for a 2-A. And even if it isn't, the Celestials themselves aren't actually as powerful as you're making them out to be, because as far as I know, the Celestials have never shown feats as impressive as
literally ripping through dimensional/universal barriers as though they were mere glass, or being comparable to a being
whose beams of light encompassed the aforementioned infinite worlds in just a few seconds. Even if you factor in the fact that each Infinity Stone holds an infinite multiverse, the scaling I showed above says that Master Hand transcends an infinitely infinite multiverse, and the amount of Master Hands that Galeem controls are shown to be far more than 6. Even if we downplay that to at least 3,000 decisions, since 3,000 decisions are the lowest amount of decisions an average human being can make each day, Dharkon would still be at least 500 times more powerful than IG Thanos, and possibly less for Shaggy by extension.
Oh, and as an addression to your "Dharkon's never shown to do that" statement, Galeem absorbed his Master Hands to unleash the beams of light, so if Galeem can do it, then since Dharkon is comparable to Galeem, Dharkon can just put Shaggy under his control and also do it.
