Arbok is a serpentine Pokémon that resembles a cobra. It has narrow eyes and several sharp teeth. Just below its head is a large hood with a face-like pattern. This pattern has over 20 possible variations. The pattern typically has two red and yellow eyespots outlined in black, a wide black streak resembling an upturned mouth, and a black V-shaped stripe above the eyespots. Arbok is capable of crushing opponents by coiling its body around them and squeezing them tightly. It can even flatten steel oil drums. If it encounters an enemy, it raises its head, mimics, and stuns the opponent using the frightening pattern on its body. It can also make eerie sounds by expelling air from its mouth. It has been stated that if any part of Arbok's body except for the head is cut off, it can regrow the rest of its body again in a few weeks. It also can detect vibrations as shown in the Pokémon the Series episode The Whistle Stop (EP130). The Pokémon the Series episode The Misty Mermaid (EP061) shows that Arbok can spend long periods underwater and survive in aquatic environments. One particular Arbok could change its pattern at any time to increase power to different stats and get invulnerability to status conditions, if the pattern is uncovered. Arbok is territorial. It lashes out at intruders with long fangs tipped with deadly venom. Vengeful in nature, it will not give up a chase once it targets its prey or an opponent, no matter how far. It makes its home in grassy savannas and plains, but it can also be found in forests and desolate wastelands alongside its pre-evolved form Ekans. In the wild, it hunts smaller Pokémon such as , and also preys on and Spearow Eggs. When hunting, it uses the pattern on its hood to immobilize prey, then constricts them, and finally poisons the target to finish them off and eat them. As shown in Pokémon Sleep, Arbok is known to display its belly while sleeping. It is theorized that Arbok does this to scare other Pokémon away by showcasing its fearsome markings.
