Silver: With a very venge­ ful nature, it won't give up the chase, no matter how far, once it targets its prey.

Crystal / Y: To intimidate foes, it spreads its chest wide and makes eerie sounds by expelling air from its mouth.

Ruby / Sapphire: This POKéMON is terrifically strong in order to constrict things with its body. It can even flatten steel oil drums. Once ARBOK wraps its body around its foe, escaping its crunching embrace is impossible.

Emerald: This POKéMON has a terrifically strong constricting power. It can even flatten steel oil drums. Once it wraps its body around its foe, escaping is impossible.
