Scyther is a mantis pok'emon that first appeared in the first generation of Pok'emon. Despite being a Bug/Flying type of pok'emon, Scyther resembles more of the dinosaurs and Dragons mixed with certain ninjas. They have 2 sharp teeth shown out front, 2 swords for appendages, they fly (minusing most Pok'emon games of course), and they are one of the most notable pok'emon to learn and use Double Team on their own.
In Anime
