Crispin enjoys cooking as well as battling, and often cooks for the other members of the Elite Four after they finish their club activities. His parents run a restaurant that he plans to take over once he finishes school. He appears to have a crush on Lacey and is ranked as the lowest Elite Four member in Blueberry Academy, situated at Savanna Plaza.
Crispin is first met in the Blueberry Academy Cafeteria, where he votes in favor of the player getting to enter the BB League. His Elite Trial consists of the player having to create a super spicy sandwich from ingredients gathered from League Club members. After the trial has been cleared, Crispin can be battled. He rewards the player with TM207 (Temper Flare) upon being beaten. When Kieran is later dethroned by the player as the BB League Champion, Crispin is alarmed that he could get demoted from the Elite Four as a result, though Kieran withdrawing from the League altogether later saves him from this fate.
Upon the third unique interaction with Crispin in the League Club Room, he will trade a Magby to the player in exchange for almost any Pokémon excluding Shiny, Legendary, or Mythical Pokémon.
