1.Stats: Should Crobat get a stat boost, Evolution, Mega Evolution or nothing?
Crobat has 535 BST, which is the second major highest BST tier a common species can get. So a stat boost is unlikely.
An evolution is impossible, unless it is a defensive split evolution.
A Mega would be perfect. Crobat has average stats, and a Mega would properly min-max its other stats.
2.Should Crobat get more abilities?
Yes. Crobat only has two abilities. Some options would be:
- Gale Wings
- Shadow Tag
- Super Luck
- Vital Spirit
Probably. Crobat has some moves, but they are pretty mediocre. Some options would be Elemental Fangs, Hurricane, Calm Mind, Psychic, Gastro Acid, Boomburst, Gunk Shot and Hyper Voice.
4.What additional typing Crobat can have?
Dark is the most obvious one. Ghost and Normal are also options.
