>>39750356both Zacian and Zamazenta have signature moves
Zacian's move breaks protect and other barrier-type moves
Zamazenta's move is a protect that deals damage and burns the attacker
both have an ability that's activated after a succesful usage of their signature moves, which stays active for 3 turns
while active, Zacian's ability makes so any of it's attacks with a normal effectiveness to become super effective
while active, Zamazenta's ability makes so any attacks it's hit with that have a normal effectiveness become not very effective
their typing is stupid, and neither have a Gigantamax form
