Scyther (Japanese: ストライク Strike) is a dual-type Bug/Flying Pokémon introduced in Generation I.
It evolves into Scizor when traded while holding a Metal Coat or Kleavor when exposed to a Black Augurite.
(Specifics may differ in past games. Refer to Game data→Evolution data for more details.)
Obviously, don't nominate any human characters. Hybrids like Cheetah or The Lizard are okay, as are shapeshifters with one set animal form (eg Professor McGonagall.)
