Lucario = Luke/Skywalker/Luke Skywalker (shoddy)
Name fits in so many ways. Luke and Lucario, just namewise, are similar. Then factor in Lucario's jedi-ish qualities. On a similar note...
Electivire = BobaFett, shares Boba Fett's immense arsenal...
Blissey = JabbaTheHutt, cause she's fat
Staraptor = MilleniumFalcon, for being a bird...
Swampert = JarJarBinks, admit it, if Gungans were pokemon they'd be Ground/Water. And are kinda similar to Swampert.
Forretress = DeathStar, appearance really. Used to use a SpecsMence named DeathStar with the idea being any attack from him being the equivalent of the Death Star firing.
Yeah, Lucario was the start of a team with Star Wars nicknames for me too.
