Me: Decimus, Latin for "The Tenth"
Rival: Furia, Latin for "Fury"
Serperior: Agre, Latin for "the fields"
Unfezant: Avis, Latin for "a bird"
Lucario: Valeo, Latin for "I am strong"
Gigalith: Petrae, Latin for "the rocks"
Raichu: Fulgur, Latin for "lightning"
Bronzong: Temporis, Latin for "of the time"
