Gertrude, Belzei

ベルゼイガートルード

He is one of the Seeds of Darkness created by the Dark King after Cure Black and Cure White defeated him for the first time. As the leader of the three Seeds, he appears to be the strongest. His primary color is purple, and he sometimes becomes quite irritated with Regine and Juna. His human alias is Yuuki Hidehiko.
He and the others use Pretty Cure and the mascots to summon the power to create, which appears later in the series, employing a pile of destroyed furniture to mimic the hill of light. At the end of the series, they merge into a single being and attempt to overthrow the Dark King using the power to create, but they fail and are killed in the process. When he fuses with Regine and Juna, his entire body, including his hair, turns dark black.
