History
Ariados is the Long Leg Pokémon, a Bug/Poison-type that evolves from Spinarak and is based on a spider, complete with a face-like pattern on its abdomen. It hunts primarily at night, spewing fine but durable threads from its mouth to snare prey and to mark trails so it can find its way back to its nest. Trailing a single strand of silk as it roams, it pursues quarry aggressively in the dark, exemplifying the predatory cunning of an arachnid.
Name & meaning
The Japanese name アリアドス (Ariados) derives from 'Ariadne,' the figure from Greek mythology who gave Theseus a ball of thread to navigate the Labyrinth—fitting for a spider Pokémon that spins webs. It may also incorporate 'ari' (アリ, the Japanese word for 'ant') and a sense of multiplicity, evoking many legs. The English name 'Ariados' is retained directly from the Japanese, preserving the Ariadne-thread connection.
