THUNDULUS? :D
I admit, I kind of like how Thundurus is homophonous with "thunderous", but I expected "Voltolos" for so long after the Japanese names came out, especially since legendaries' names relatively remain untouched. Plus, you hardly get to say "Volt" in Pokemon names these days..? BARRING VOLT TACKLE, VOLT SWITCH, AND VOLBEAT. @_@ :<
