Pokédex entries

Red 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.
Ruby Sapphire	OMASTAR uses its tentacles to capture its prey. It is believed to have become extinct because its shell grew too large and heavy, causing its movements to become too slow and ponderous.
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.
Emerald	An OMASTAR uses its tentacles to capture its prey. It is believed to have become extinct because its shell grew too large, making its movements slow and ponderous.
Diamond Pearl Platinum	It is thought that this Pokémon became extinct because its spiral shell grew too large.
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.

X	Its tentacles are highly developed as if they are hands and feet. As soon as it ensnares prey, it bites.
Y	Once wrapped around its prey, it never lets go. It eats the prey by tearing at it with sharp fangs.
Omega Ruby Alpha Sapphire	Omastar uses its tentacles to capture its prey. It is believed to have become extinct because its shell grew too large and heavy, causing its movements to become too slow and ponderous.
Ultra Sun	Its heavy shell is thought to be the reason this ancient Pokémon died out. It’s apparently a distant ancestor of Octillery.
Ultra Moon	It wraps its prey in its tentacles to immobilize them and then finishes them off with its sharp fangs.
Let's Go Pikachu Let's Go Eevee	Its sharp beak rings its mouth. Its shell was too big for it to move freely, so it became extinct.
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.
Brilliant Diamond Shining Pearl	It is thought that this Pokémon became extinct because its spiral shell grew too large.
