Araquanid

Above average special bulk coupled with a good defensive typing allows Araquanid to take most neutral STAB attacks comfortably, making it a good offensive tank. Thanks to Water Bubble, Araquanid can deal reasonable amounts of damage with its Water STAB attacks despite its low base Attack, and check common Intimidate users such as Incineroar and Landorus-T and Fire-types such as Mega Charizard Y. It is also able to provide permanent speed control with Sticky Web and protect its allies with Wide Guard support. Unfortunately, Araquanid's low Speed stat means it almost always takes damage before doing anything useful. It also competes with other more popular bulky Water-types such as Tapu Fini, Volcanion, and Suicune for a spot on teams. Furthermore, a shallow movepool and a lack of coverage options also make Araquanid a rather predictable Pokemon. Its low base Attack also means that Araquanid cannot deal any significant damage besides with Liquidation.
