Rapion

Diamond +2: It grips prey with its tail claws and injects poison. It tenaciously hangs on until the poison takes.

Pearl: It lives in arid lands. It buries itself in sand and lies in wait for unsuspecting prey.

Platinum +2: As soon as the tail claws close, its needle tips secrete poison. It can survive a year without food.

HeartGold +3: It burrows under the sand to lie in wait for prey. Its tail claws can inject its prey with a savage poison.

Black 2 / White 2: It lives in arid regions and can go without food for a year while waiting for prey.

Sword: After burrowing into the sand, it waits patiently for prey to come near. This Pokémon and Sizzlipede share common descent.

Shield: It attacks using the claws on its tail. Once locked in its grip, its prey is unable to move as this Pokémon’s poison seeps in.

Legends: Arceus: Its claws are not only razor-sharp but poisonous, making Skorupi a highly dangerous Pokémon. It seems to be weakened by cold temperatures, however.
