Scizor...is correct!
1. It was called the Scissors Pokémon in Gen II, but from Gen III onward, it was called the Pincer Pokémon.
2. It's a Bug/Steel type, a typing that only five other Pokémon (Forretress, Trash Cloak Wormadam, Escavalier, Durant, and base form Genesect) have.
3. The Iron Mask Marauder from Pokémon 4Ever and Goone from Zoroark: Master of Illusions used it; both were antagonists in their films.
4. It's not a Legendary.
5. Its Silver/SoulSilver Pokédex entry claims that their wings aren't used for flying, but to adjust body temperature.
Again, I'm really sorry for this one. I might have gone overboard when I tried to make it challenging.
