Pokedex Entries
Game | Entry |
---|---|
Red | A prehistoric POKéMON that died out when its heavy shell made it impossible to catch prey. |
Blue | A prehistoric POKéMON that died out when its heavy shell made it impossible to catch prey. |
Yellow | Sharp beaks ring its mouth. Its shell was too big for it to move freely, so it became extinct. |
Gold | Apparently, it cracked SHELLDER’s shell with its sharp fangs and sucked out the insides. |
Silver | Once wrapped around its prey, it never lets go. It eats the prey by tearing at it with sharp fangs. |
Crystal | Its heavy shell allowed it to reach only nearby food. This could be the reason it is extinct. |
Firered | Its tentacles are highly developed as if they are hands and feet. As soon as it ensnares prey, it bites. |
Leafgreen | Despite having strong fangs and tentacles, it went extinct when its heavy shell made it unable to catch prey. |
Heartgold | Apparently, it cracked SHELLDER’s shell with its sharp fangs and sucked out the insides. |
Soulsilver | Once wrapped around its prey, it never lets go. It eats the prey by tearing at it with sharp fangs. |
UltraSun | Its heavy shell is thought to be the reason this ancient Pokémon died out. It’s apparently a distant ancestor of Octillery. |
UltraMoon | It wraps its prey in its tentacles to immobilize them and then finishes them off with its sharp fangs. |
Sword | Weighed down by a large and heavy shell, Omastar couldn’t move very fast. Some say it went extinct because it was unable to catch food. |
Shield | Omastar’s sharp fangs could crush rock, but the Pokémon can attack only the prey that come within reach of its tentacles. |
