Lore

Biology

Anorith is a greenish-grey arthropod, 0.7 m tall and 12.5 kg. Its round eyes sit on stalks, its head is black in the middle, with two red teardrop-shaped spots, and an X-shaped mouth is on its underside. Two large segmented claws hang beneath the head, and each side of the body carries four white, red-tipped wing-like limbs.

Behaviour

Anorith is a fast swimmer, rowing through the water with its eight wings like oars. The Pokédex says it hunts with its pair of claws, pulling prey out from among rocks on the sea floor. Revived Anorith released into today's ocean do not thrive, because seawater is no longer what it was in their era.

Habitat

The Pokédex says it lived in the warm seas of ancient times, about 100 million years ago, and it is classed as a water's edge Pokémon.

Powers

Its Ability is Battle Armor, which blocks critical hits, with Swift Swim hidden. By levelling up it learns Metal Claw, Crush Claw, Rock Blast and X-Scissor. With base Attack 95 and Speed 75 it is a quick, hard-hitting early fighter, but its Defense is only 50.

Name origin

Anorith may combine Anomalocaris, an ancient sea animal, with anorthosite, a rock, and the suffix -lith, 'stone'. The Japanese name is Anopth (アノプス), which may blend Anomalocaris with Triops, a genus of small crustaceans.

Design inspiration

Anorith is closely based on Anomalocaris, an ancient marine arthropod, with some trilobite features. Bulbapedia adds that it greatly resembles brine shrimp, which have similar eyes and feathery protrusions along their sides.

Evolution notes

Anorith evolves into Armaldo at level 40.

In the games

Anorith returns from a Claw Fossil that is revived at Rustboro City's Devon Corporation in Ruby and Sapphire, where it first appeared. It returns in the Sword and Shield Expansion Pass, with Surf encounters at Ballimere Lake, but Bulbapedia lists it as unobtainable in Scarlet and Violet and in Legends: Z-A.

In the anime

Anorith debuted in 'Where's Armaldo?', where Professor Proctor and Annie Proctor studied it on Wales Island with the other Hoenn Fossil Pokémon. It eventually evolved into Armaldo.

Pokédex entries

Anorith can swim swiftly by pulling its eight wings through the water like oars on a boat. This Pokémon is an ancestor of modern bug Pokémon. (Shield)

This Pokémon was restored from a fossil. Anorith lived in the ocean about 100,000,000 years ago, hunting with its pair of claws. (Sword)

This is one kind of primeval bug Pokémon. With eight wings, it could apparently swim a lot faster than you'd expect. (Ultra Moon)

When restored Anorith are released into the ocean, they don't thrive, because the water composition has changed since their era. (Ultra Sun)

Anorith is said to be a type of Pokémon predecessor, with eight wings at the sides of its body. This Pokémon swam in the primordial sea by undulating these eight wings. (Sapphire, Alpha Sapphire)

Anorith was regenerated from a prehistoric fossil. This primitive Pokémon once lived in warm seas. It grips its prey firmly between its two large claws. (Ruby, Omega Ruby)
