This Pokémon is referred to in the Violet Book. It is said that when this monster curls its body and rolls to attack, it leaves a trail gouged into the ground, as if it had scorched the earth.
Iron Treads is a Ground/Steel-type Paradox Pokemon in Pokemon Scarlet and Violet (SV).
In the latest trailer for Pokemon Scarlet and Violet, two brand new forms for Donphan were revealed. It looks like they will be version-exclusive Pokemon for Scarlet and Violet. One looking much more like it is from the past and the other from the future. This seems to line up with the box legendaries, Koraidon and Miraidon. Here is the latest on the new Pokemon Donphan Forms, Great Tusk and Iron Treads.
It is worth noting that these Pokemon will have names that almost feel like nicknames trainers would give them. This happened with Type: Null in Pokemon Sun and Moon as well.
There had been rumors that these types of Pokemon would be called Paradox Forms. They would relate to the story of the game in some way. This has yet to be confirmed by the Pokemon Company but once it is or is at least revealed to be something else, The Game Haus will have it covered.
Pokemon's newest 'mons Great Tusk and Iron Treads look an awful lot like Donphan, and that's already sparked a whole host of theories - chief among them is the idea that these two are future and past versions of the elephant 'mon we met all those years ago back in Gen 2.
According to leaks from July, one of the new mechanics in Scarlet & Violet is Paradox forms, but it's unclear what that means exactly. Some timey wimey technobabble seems to be distorting a few different 'mons, though how that makes them paradoxes remains to be seen
