>>54237317Ground type is also heavily associated with sand, so I think you can get away with having the Eeveelution be something that clearly lives among the sand, especially as long, strong hind legs are a feature of all Eeveelutions. Still, do let me know if you find a short-limbed burrower design for a ground type Eevee. I'd be interested to see it since, as I mentioned, the overwhelmingly majority of ground type Eeveelutions designs I've seen are "just make it out of sand" or "just make it an Egyptian sphynx" or in some cases both. Not very inspiring, whereas Bristleon is, as you say, beautiful.
>>54237352I was gonna go Metal Coat for steel and King's Rock for dragon because these are the only trade evolution items that presently evolve more than one Pokemon, so Eevee's genes responding to them made sense to me. I was actually going to go Moon Stone for poison as a reference to the Nidos, since moon stone is presently the only gen 1 stone that doesn't evolve Eevee, and I was gonna go sun stone for ground since if we're gonna use moon stone, it creates a bit of an unspoken obligation to use sun stone as well, I'd think.
For rock, I had the idea of using this design, since cuddleability is very important for Eeveelutions, and making one literally out of rocks doesn't fit with that. Fossilmons are the other thing that is considered "quintessentially rock type", so such a design still represents the type well, and I was thinking could be acquired by having the local fossil reviving scientist attempt to work on the fossil of an ancient ancestor of Eevee, only for them to tell you the fossil is too badly degraded... but interestingly DOES seem to be charged with energy now... The fossil would then function as an evolution stone to transform a modern Eevee into Tricerion.
It also once again keeps the body detailing limited while emphasizing the tail, claws, and horns. let me know your thoughts.
