Prior to Sparks: XYZ
Dedenne use to belong to an elderly man named Albert. Due to his old age he was slowly dying at was checked into a hospital. Dedenne saw this as Albert leaving him and decided to go off into the wild. Upon Clarissa and her friends arriving in Shalour City, Nurse Joy recognized Dedenne and returned it to Albert. Upon seeing his trainer in worse condition, Albert decided that Dedenne should go with Clarissa and handed her it's Poké Ball.

Sparks: XYZ
Clarissa caught Dedenne on Kalos Route 11 after it shocked her when stealing her food. Clarissa, enraged by the Pokémon's action did what came to mind, threw a Poké Ball at it. Much to her surprised the Antenna Pokémon was already owned by another trainer. Jax and Mason made the observation that Dedenne didn't want to go back to it's Poké Ball and to instead keep it out with her. This marks the first time since Sceptile that she has had a Walking Pokémon. Clarissa later found his old trainer but he was slowly dying and Albert gave her Dedenne's Poké Ball.

Personality
Dedenne is an affectionate Pokémon.
