Deck Knight
Blast Off At The Speed Of Light! That's Right!
^I like that learnset as a strawman. It seems like it needs a few more non-STAB moves. Maybe replace a STAB move or two.
With those wings in Cyzir's drawing, it sure seems like Wing Attack fits --even though it isn't flying. The move description is "Strikes the foe with wings spread wide." Those icy wings look like they could do some damage. It would be the first non-flying character to get Wing Attack. But, Empoleon was the first non-flyer to get Drill Peck. My assumption is because it just makes so much sense based on Empoleon's design. With that logic, Wing Attack on our ice bug should fit.
Right now, with the exception of a couple of moves -- every move is made for battle. Nintendo learnsets rarely are so efficient. Maybe give it Scary Face, even though this bug is so fast, it would never need it. It DOES have a scary face, IMO. Also maybe give it Razor Wind, even though it's a totally worthless battle move. With all those sharp icy edges, Razor Wind seem appropos.
Just a few suggestions. But, I like Deck Knight's starting point.
Technically Scizor was the first, but it evolves from Scyther.
Nintendo learnsets are based around the principle that you'll be using the pokemon in the game, so it makes no sense to have say Lv 20 Ice Beam, even on ice types. Usually there's a progression upward in move power over time, and support options vary heaviliy from pokemon to pokemon. Bulbasaur doesn't get Sleep Powder until its 30's, whereas Bellsprout, Oddish, and Butterfree learn it in the teens.
