Akanbes are the main monsters of Smile Pretty Cure!. To summon an Akanbe, a series villian shouts out "Come out, Akanbe!". Akanbes can only emit cries of "Akanbe", "Aka" or "Beh". They are voiced by voice actor Sasaki Hiroo. Akanbe literally means the action of "pulling one's eyelid down and sticking out one's tongue".

The color of the Akanbe's nose determines its strength.
