I honestly think there should be no new moves its created, no non-legendary has his own unique move, save for vespiqueen, whose moves aren't even unique, and pikachu (I think its the only one?).
That's only in the 4th generation. There were quite a few in 3rd, most notably Sceptile's Leaf Blade, Pichu's Volt Tackle, Lugia's Aeroblast (like anyone used it anyway), and Ho-oh's Sacred Fire. So it's entirely feasible this pokemon could have it's own move.
