Special abilities
Most of Omastar's abilities are the same as Omanyte's, only stronger. Omastar can now learn how to use Stone Edge. Like most fully-evolved Pokémon, it can learn Hyper Beam and Giga Impact.
Behavior
Omastar, unlike Kabutops, is far more defensive. While Kabutops prefers to slice prey apart or swim after them, Omastar does not. Omastar has a high Special Attack suggesting that it prefers waiting for prey to come near it so it can attack. It is not as fierce as Kabutops and probably does not move as much either, preferring to stay rooted to a spot, waiting.
Omastar also appeared in Fossil Fools, alongside its pre-evolved form Omanyte. These Pokémon were discovered to be living in the Ruins of Alph, but they moved into a museum.
Omanyte and Omastar, Kabuto and Kabutops. It is believed these Pokémon became extinct tens of thousands of years ago. The details of their behavior are shrouded in mystery. Though some have speculated that they may still exist, none of these Pokémon have ever been seen alive.
Omastar, the evolved form of Omanyte. This extinct Pokémon is believed to have used its sharp fangs to break through the shells of its prey in order to feed.
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.
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.
Omastar is the only Fossil Pokémon that has been given a reason for extinction; its shell was too heavy for it to move, thus it starved to extinction.
This may also be a reference to the giant orthocone, ancestor to the modern octopus. The orthocone resembled an octopus but it had a long pointed shell that was slow and cumbersome.
