>>43721183>climbing mountainsHmm. Well, what are the obstacles?
>cold>oxygen>falling>the climbing itselfFor cold, a fire type would serve you well, obviously. You've got a huge selection to pick from. Maybe Charizard since it can fly to boot?
>oxygenI couldn't find any Pokemon that can straight up provide air. But apparently Shedinja doesn't even breathe. So it could be useful as an emergency lifesaver if you pass out from lack of oxygen.
>fallingLiterally any flying type. More likely a fire/flying or ice/flying type. Articuno is the only example of the latter, so the former is most likely. Charizard is the largest and sturdiest fire/flying type, so it fits here too.
>the climbing itselfA rock/ground type perhaps? Maybe an Ice/Ground type like Alolan Sandslash could help? It's bigger than regular Sandlash too, standing at about 3'11. Could probably use Rock Climb to save you.
