Princess Peach

Princess Peach Toadstool is the princess of the Mushroom Kingdom. She first appeared in Super Mario Bros., released in 1985. She was created by Shigeru Miyamoto to be the damsel-in-distress throughout most Mario games. She usually resides in her castle along with many Toads. Her kingdom is often attacked by the Koopa Troop, led by Bowser. She is one of the main heroines of Super Mario Bros. X: Sea Side Adventure, in which she was gone missing in the Sea Side Kingdom and seperated from Toad and Yoshi then got sealed within the Character Block by Wart.

Mario
Since Peach's debut appearance, Mario and Peach have always been shown to be in a romantic relationship. In Super Mario Bros. X: Sea Side Adventure, Mario came to free her from the Character Block, then she joins the group to help them save King Varun and retrieve Princess Marina. Her main relationship is with Mario; Peach often comes to his help and she often cheers him up. Though Peach doesn't team up with Mario often during battles. However, Mario will always appear to protect Peach, regardless of any kinds of situations he goes into.

Toad
Toad is Princess Peach's obedient servant, and often tries to protect her. More than once he has gotten kidnapped by the Koopa Troop trying to save her from Bowser for several years, and other times he is seen to dote on her. Since Mario and Luigi saved Toad in Sea Side Adventure, he was more confident and strongly wants to do anything to save and protect the princess, while asking the Mario Bros. to forgive him for being weak. When Toad found Princess Peach along with Mario, Luigi and Yoshi, he was so happy to see her again and made his promise to never leave her and fight alongside her. Princess Peach then became more fond of him and protect each other's back during battles. Toad is the third person Princess Peach other teams up with.

Link
Mario and Link where on bad terms but end up being good friends, which is the same as Princess Peach. Link mistook Peach as Zelda and tried to take her with him since they first saw each other, yet he noticed only one difference; her ears. Peach recalls having seen one of the Hylians who Link resembles to. As the story goes on, they became great friends. He is always here to protect her, as he still feels familiar with Peach. Link is the first person Princess Peach often teams up with.

Goldian Duck
Goldian Duck had fell in love with Princess Peach ever since he led his eyes on her, though she is still remained oblivious to his feelings and often confusedly said that they aren't a couple, which despresses him. Goldian is a jealous guy; he hates it when Mario gets close to her and ask her why she is with Mario instead of him. Despite that, Peach gets along well with him. Goldian Duck is the second person she often teams up with during battles.
