Lyra's Azumarill (コトネのマリルリ, Kotone no Marilli) is the second Pokémon Lyra caught in the Johto region, and is her favorite Pokémon, as well as her strongest.
Azumarill is one of Lyra's main Pokémon and appears to be very affectionate towards her. Upon appearing in the Hora region, Marill is revealed to have evolved into Azumarill.
Azumarill is a blue mammalian Pokémon. It has a nearly ovoid shape with a white and white-speckled, bubble-like pattern on its underside, which helps it to camouflage itself in the water. Azumarill also has elongated, rabbit-like ears with red ear insides. Azumarill still possesses the wiry black tail and blue "bubble" it had in its pre-evolved forms, except the bubble is smaller. Its eyes are circular with blue irises.
It lives in water virtually all day long. When it plays in water, it rolls up its elongated ears to prevent their insides from getting wet. If Azumarill spots a drowning Pokémon, it will make air balloons to help it breathe.
By keeping still and listening intently, it can tell what is in even wild, fast-moving rivers. Azumarill can make balloons out of air. It makes these air balloons if it spots a drowning Pokémon. The air balloons enable the Pokémon in trouble to breathe. It's Ability, Huge Power, doubles the user's Attack stat.
