Kjolmar used to be the geeky assistant of Professor Juniper at her lab in Nuvema Town (Unova) and was later replaced by Bianca. Juniper suggested that Kjolmar could travel to Professor Sycamore's laboratory in Lumiose City in order to assist in the research concerning mega evolution. And thus Kjolmar and his squirtle called 'Coop' (his very first pokémon) made their way to the Kalos region on the back of Kjolmar's Hydreigon. There, he met the trainer Olli who had came all the way from Sinnoh in order to defeat the Kalos gym leaders. Kjolmar's Squirtle Coop and Olli's Chimchar seemed to share a strong bond and since Olli also has an Absol, Sycamore thought it would be a good idea if Kjolmar followed Olli on his quest. That way he could study mega evolution in the field and at the same time maintain the friendship between Coop and Chimchar. During their quest, Kjolmar befriended and captured an Espurr.
