Feliks was once a powerhouse trainer in Europe who spent countless hours training daily, but his recent laid-back approach has had him sliding down in the ranks. To the surprise of many though, he keeps making comeback after comeback—making him currently the most unpredictable trainer in competitive battling. Feliks still loves the sport but believes he's reached a point where he doesn't need to keep up with the crowd. He feels satisfied at the level where he is now, but to some degree, it is also due to burn out and homesickness. Feliks however has been curious about Pokemon Contests lately and has wondered if that's his true calling.

Although he doesn't specialize in it, Feliks grew up idolizing several Polish trainers who were masters at raising Fairy and Psychic-types. Much of his team his inspired by those trainers, namely his Rapidash, Gardevoir, Delphox, and Hatterene. His Rapidash serves as his ace and was his first Pokemon as a Ponyta. His starter was gifted to him by his mother.
