Quaxwell is a white, duck-like Pokémon with blue eyes, a pointed yellow beak, a teal brow that flares into two branches, and a round blue crest atop its head that droops toward the back. Blue and teal feathers adorn its chest, forearms, tail, and feet, with the three feathers at the end of its arms resembling fingers, and its long legs end in yellow feet that wrap around its ankles like ballet shoes. Its crest can absorb impacts to shield it from attacks, though doing so may leave the crest unkempt and weaken Quaxwell's body and mind. It evolves from Quaxly at level 16 and into Quaquaval at level 36. Prior to a version update in Generation IX, Quaxwell and its pre-evolution were unable to learn Substitute and Sleep Talk via TM.
Quaxwell physically appeared in the main series in Dance, Quaxly! The Blue Medali Step!, after Dot's Quaxly evolved during her Tera Training battle against Larry, Terastallizing into a Water type as a Quaxwell in the same episode.
Quaxwell may be based on a crested duck or goose and a ballet dancer, with elements of carnival performers such as those at the Rio Carnival or the Carnival of Santa Cruz de Tenerife. Its feathers and crest also resemble a swim suit and swim cap, suggesting synchronized swimming as another possible inspiration.
