Most people dislike running weak mons that have little to no point within the meta. However I myself run a Level 5 Aron within my team.
Aron @ Focus Sash
Ability: Gale Wings
Level: 5
EVs: 196 Atk / 116 Def / 196 SpD
Adamant Nature
- Endeavor
- Aerial Ace
- Toxic
- Protect
Now this is mainly an anti-lead pokemon and once attacked will be left with 1 hp. It's a fear Rattata, except this one is immune to toxic. So yeah, That's basically it.
