Cologne is a former fairy mascot in Heartcatch Pretty Cure.
Cologne vaguely resembles the other fairies and has the same white body and attributes. He has slanted eyes with sharp light purple heart markings above them to resemble his sharp shaped tail and bangs. He has small white light purple and white ears and a single, sharp silver ornament on the left side of his head. He has a sharp purple neck ornament with a silver heart attached to it.
Cologne was very calm and caring for his partner. Unlike the other fairies, he was mature in thought and action. He worried about Cure Moonlight constantly for taking the burden of Pretty Cure, but understood the kindness in her heart.
