Galarian Weezing consumes polluted air and poisonous gases for sustenance. The by-product of this consumption is purified air, which is spewed out from the tops of its heads. The toxins accumulated within Weezing's body form into concentrated poison gas clouds that leak out and drift around it. This gas is so potent that even a whiff is enough to stun and immobilize an opponent, making it Weezing's best weapon during battles.
Weezing is confirmed brap sniffer in swish
