Pokemon GO Gym Combat Mechanic Questions

[advancedip]

Just 2 meager questions…

If 4 people attacks a gym, does the defending pokemon attack all 4 pokemons at once?

Also, what is the strongest pokemon that can burn threw revives and potions?

1. Yes

2. Not sure I understand that question?

Blissey takes the cake for the most annoying defender, thankfully Mewtwo is here to rip her apart with Psystrike (kind of reminiscent of Gen 5 competitive tbh)
