Remoraid is the Jet Pokémon, a pure Water type that first appears in Generation 2 at dex #223. It evolves into Octillery starting at level 25. Its back stripes and fins recall the barrel, trigger, and hammer of a revolver, and because it looks so little like Octillery, for a long time nobody believed the two were linked by evolution.
It powers its long, accurate water shots with its abdominal muscles, often knocking prey such as Burmy out of the air. Bulbapedia draws a direct parallel between Remoraid and Qwilfish, noting both are Water-type Generation II Pokémon that are version-exclusive counterparts, Remoraid to LeafGreen and Qwilfish to FireRed, found in the same in-game locations.
Remoraid made its animated debut in The Light Fantastic, where a multitude of them lived on Remoraid Mountain. It later turned up in a Joy of Water Pokémon flashback tied to Nurse Joy's fear of the type, in a shipwreck under a Mantine's protection in Mantine Overboard!, and among Marcellus's Pokémon in Octillery The Outcast!, where some of his Remoraid evolved into Octillery.
Remoraid's first card arrived in the Neo Revelation Common illustrated by Miki Tanaka, with Neo Destiny and Aquapolis (art by Mitsuhiro Arita) following soon after in the WOTC era. The line has run steady since, with Midori Harada, Suwama Chiaki, and Minahamu each contributing entries from the EX era through Journey Together, up to the Chaos Rising printing from Mori Yuu in the Mega Evolution era. Suwama Chiaki illustrated both Remoraid Commons in BREAKthrough.
