Aggrostella

Sun: Toxapex crawls along the ocean floor on its 12 legs. It leaves a trail of Corsola bits scattered in its wake.

Moon: Those attacked by Toxapex’s poison will suffer intense pain for three days and three nights. Post-recovery, there will be some aftereffects.

Ultra Sun: To attack, this Pokémon sends toxic spikes flying at its enemies. Ones that come close get mown down by the claws on its feet.

Ultra Moon: With its 12 legs, it creates a dome to shelter within. The flow of the tides doesn’t affect Toxapex in there, so it’s very comfortable.

Sword: To survive in the cold waters of Galar, this Pokémon forms a dome with its legs, enclosing its body so it can capture its own body heat.

Shield: Within the poison sac in its body is a poison so toxic that Pokémon as large as Wailord will still be suffering three days after it first takes effect.
