Groudon and Hisuian Arcanine have both been shown walking through lava unharmed in different Pokemon media. Magmar and Charizard have been shown to be inside lava without being harmed in a Pokemon episode. And in Pixelmon's Nether, multiple Fire-type Pokemon like Slugma and Turtonator are shown to be floating on the lava, so why not take it a step further and let players ride some Fire-type Pokemon on lava? Since diving into lava like how water mounts dive into water is probably realistically a bad idea from the player's standpoint, lava mounts will ride on top of the lava like striders, except they will be faster than striders.
Possibly any Fire-type mount as well as Groudon will qualify to become a lava mount, but I felt the following Pokemon should definitely gain the ability to carry the player across lava (there's also Magcargo and Torkoal, but they might be too small to carry a player realistically):
- Heatran
- Magmar
- Magmortar
- Hisuian Arcanine
- Volcanion
- Groudon
- Camerupt
- Entei
- Typhlosion
- Turtonator
While they aren't as high priority as the Pokemon in the above list, maybe Kantonian Ninetales, Kantonian Rapidash, Kantonian Arcanine, Blaziken, Flareon, Houndoom, Infernape, Emboar, Unovan Darmanitan, Delphox, Pyroar, Torracat, Incineroar, Salazzle, Blacephalon, Cinderace, Centiskorch, Skeledirge, and Coalossal will become lava mounts too. Charizard, Kantonian Moltres, Volcarona, Reshiram, and Chandelure are already flying mounts, but I thought maybe they would be unable to sink in lava while mounted, making them both flying mounts and lava mounts.
I'd love to see lava mounts in a future version of Pixelmon.
