1.Stats: Should Donphan get a stat boost, Evolution, Mega Evolution or nothing?
Donphan already has 170 BST gap from Phanpy, so it wouldn't likely get more. It also shares its BST with its counterpart Ursaring, which shares its 500 BST with other bears.
An evolution would be interesting, but it would be just an upgraded Donphan.
A Mega can work with a good ability.
2.Should Donphan get more abilities?
Yes. Donphan has only two abilities and needs one more. Some options would be:
- Rock Head
- Sand Force
- Sheer Force
- Thick Fat
3. Should Donphan get more moves?
Generally yes. Moves like Swords Dance and Slack Off would help Donphan. Power Trip, Icicle Crash, Psychic Fangs and Wide Guard are also options.
4.What additional typing Donphan can have?
Normal, Rock, Ground are the obvious ones. Fairy and Fighting are less obvious ones.
