Gotta disagree here. Most gym leader pokemon are around the same in power, just mild power gaps. This means Raihan's pokemon can all generally fight on equal grounds with the rest of his pokemon. He still has trouble with him despite G-maxing, meaning that G-max doesn't have that massive of a powergap. It is a powergap for sure but hell, we've been shown that it is closer to Mega Evolution in portrayal, Megas usually only boosting Pokemon to an extent where they somewhat change the tide in battle, not completely overwhelm people instantly. Now regarding mega evolutions...
Yes, but what my point was, if Piers just scales down from Raihan, then its not really that problematic to do that, because a very rare few of gym challengers ever make it to him, and let alone win. It's not like every gym challenger, or even every other gym leader, would be affected by this.
Z-moves don't grant jumps in several tiers.
Pikachu as an example says otherwise. The page is outdated AFAIK, but even currently, Pikachu's SM key has a separate High 3-A tier via 10,000,000 Volt Thunderbolt and Gigavolt Havoc. I don't see why Z-moves, that are powered directly by Necrozma, wouldn't grant a jump in several tiers.
(Especially since they're attack moves that don't scale directly to the user, but thats besides the point).
Mega Evolution...now that's tricky, and that's mostly cause I am planning up some revisions that could put base Rayquaza above 5-B, same going for Mewtwo, Mew, ect. In short, that kind of jump isn't guaranteed, and, worst of all, its not a jump to 2-A, the god tier.
I mean, sure, their bases can be higher than 5-B, but the point I made here still is that we find it acceptable for mega evolutions to grant quite a considerably big boost in power that can span several tiers, currently. So I don't think it's impossible for Dynamax to grant a similarly potential boost like that to other Pokemon. At least the legendaries roaming around in an area thats flooded with Dynamax energy compared to typical power spots.
Also, side note, the scaling for Mega Rayquaza is entirely based on speculation. It is simply assumed that since Rayquaza and Mewtwo are in the same tier, Rayquaza would have the same type of boost as Mewtwo. But I digress, let's not start that discussion here since that'd be for another day.
This was actually already brought up in another thread and was explained away.
And that would still be scaling basically every big legendary in Galar to 2-A because Eternatus exists. I'll extrapolate on that in the next point
Im aware of this. The purpose of why I brought this up was moreso to fix the "every legendary period becomes 2-A" issue. It would be restricted to certain versions amped by a power they normally don't scale to on their own, and the legendaries in the raids pretty much only fight the rental mons in D-maxed states instead of their regular forms.
That system is nowhere near comparable to something as lore-heavy as Ultra Wormholes. To me Rental Pokemon are far more closer to a game mechanic to make things a bit easier for players, not something that should be taken too seriously in lore. It's basically saying that these specific, sometimes unevolved and not even max level mons are powerful enough to fight (in their base forms mind you) Dynamaxed 2-A gods. Nobody else is that powerful, just these specific pokemon. Can't you see that this is some "Black Panther hurting the Silver Surfer" level of outlier here. If we start acknowledging this as something significant then why don't we acknowledge every single gen 4 legendary fighting each other in the manga, or every legendary fighting each other in the Hoopa movie as legitimate? Those are far better and far clearer cases of scaling so uh, what gives? If "Regigigas slams Dialga and Palkia" or "Rayquaza fights Giratina" can't get properly acknowledged then why should we acknowledge "Leon states Eternatus is the strongest legendary and Leon is strongest trainer so he must scale above these random mons we don't even know if he has seen or heard of that for some reason can fight 2-A space-time deities despite not being special in any way".
Im not saying I don't see what you're saying, because as I said, I am personally split when it comes to this. And I agree Ultra Wormholes have much more bigger legs to stand on when it comes to their placement in lore.
The issue, however, on why this being or not being a game mechanic is a debatable topic is because the existence of these mons, these raids, and these legendaries inside them, are acknowledged in-universe by the actual characters. They themselves state that Pokemon, that don't normally exist in Galar, are present there, so it doesn't seem as if this is just an equalized leveling kind of thing to make things more fair. Unusual Pokemon with unusual capabilities are stated directly to exist there, so while Alola's ultra wormholes have more in-depth backing to them, the raids are in a similar vein to them with direct acknowledgement in-universe.
All I'll say, because the course of this discussion depends on it and eliminates a lot of back and forth, is that we have to decide if the above is to be considered a legitimate in-universe existing thing, or is still a game mechanic.
Ok then let's bring up someone like Darkrai who doesn't do that and still would be above UN and use Z-moves. Z-moves only power up the pokemon to the extent that they can be powered up, not to the same level like you're suggesting Dynamax does.
Those Totem pokemon vary in power from being defeated by literal newbies to being the boss of high level trials. It isn't uniform and that is what's important
You're missing the point. What I am saying is, there absolutely no reason for Dynamax to boost the pokemon to the same exact level, that being 2-A. Under your suggestion Dynamax would boost Dialga/Palkia and Molters to similar levels of power, when logically their power should be different, similarly to how even just the normal dynamax forms have differnet levels you can upgrade them to and then the fact that low level Pokemon in the wild are far weaker than high leve Pokemon. The boost is proportional to the power of the pokemon, we just don't know to what proportion.
Oh I think I see what you mean now. In that case, I'll rephrase my suggestion a bit. Instead of thinking all Dynamax states are 2-A, what about Dynamax being able to vary,
potentially up to 2-A, because of it boosting 2-A Pokemon? All that then comes down to is what Pokemon and their specific Dynamax forms have feats of doing what.
