Tesla, affectionately called Tes by his friends (and Stringbean by one in particular), was born into an affluent family and grew up on the relatively quiet and peaceful Lux Island. As a child, Tesla was enamored with Electric-Type Pokemon and that love still resounds like thunder today. Tesla helped found the Mirova League alongside two phenomenal battlers starting out as a member of the Elite Four, eventually becoming Champion of the Region, after putting in countless hours of hard work into the League and often drags the Elite Four into helping him to work-much to the once diligent Tael's dismay.

Tesla loves spending time with the League, working on his own, randomly thought-up, specialized projects and, obviously, battling. While Tesla is a charismatic individual who is often seen surrounded by people, he's actually pretty introverted and prefers to be alone or not around many others. Tesla can be overly friendly with some people and it's actually very rare for him to actually outright hate another person. Tesla works painstakingly hard to keep the league in order, making sure everything is run as smoothly and systematically as possible. Is this to say that Tesla is without his faults? Oh hell no. He tends to ignore people a LOT,  typically doesn't heed the advice of others until it's too late and will contradict himself a lot of the time. In spite of his faults, Tesla has earned the friendship and respect of his friends and without him, the League would not be the same.
