Regina

Regina (レジーナ, Regina)? is the former secondary antagonist of Doki Doki! Pretty Cure. She is one of King Jikochuu's daughters, and acts as his second in command. Over the course of the series, she strikes up a friendship with Aida Mana.

In the novel, she fuses with Madoka Aguri and Ai to become a Pretty Cure known as Cure Joker (キュアジョーカー, Cure Joker)?.

Regina has long blonde hair that reaches down to her ankles and is decorated with a red bow on the top of her head. She wears a dark grey dress decorated with red details and a black jacket. When her evil outfit debuts after she is brainwashed by King Jikochuu, her bow, and details on her outfit are purple. Regina's eyes are normally blue, but when she is brainwashed or controlled by the red Royal Crystal, her eyes turn red. Her skin and hair even become pale once she is brainwashed.

As Cure Joker, she retains her blonde hair but has expanded and also has additional flairs that resemble Cure Ace's red hair. Her right eye is red, while her left eye is blue. She wears a purple ribbon on her head's left side, a pink ribbon on her right, and a red and gold crown with fuchsia frills. Her long-sleeved dress is a mix of black and red accents, white frills and collar, a red rhombus gem donned on her neck, a dark pink ribbon with a light pink heart on her chest, dark pink and purple back ribbons, dark pink rims, and adorned with yellow accents, a blue spade, and a green clover. She also has long black and red socks, respectively, the same as the accents of her indigo shoes. Her shoes also have a pink and purple ribbon respectively.

Regina is selfish, vain, and spoiled. She treats everyone like peasants and hates anyone who is more beautiful than her. She threatens the Selfish Trio if they don't do what she wants. She is also playful and tries to make Mana play with her.

At the end of the season, Regina is no longer evil and has become a friendlier person, despite still being a bit clingy. She is still somewhat bratty, selfish, and childish, but truly cherishes her family and friends.

Cure Joker (キュアジョーカー, Cure Joker)? is Regina's alter ego. She transforms with the phrase, "Pretty Cure! Double Up!", and fuses with Aguri and Ai. It is currently a one-time transformation for Regina so far.

The red eye belongs to Aguri, while the blue eye belongs to Regina.

In this form, Regina and Aguri speak in unison. However, when their opinions clash, Regina's voice converses with Aguri's.
