Scyther, the Mantis Pokémon. Its claws are sharp as swords, and it is a powerful flyer. This Pokémon is rarely seen by humans and almost never captured.
– Ash’s Pokedex
Scyther is one of the cool bug types of Gen I. Despite the fact that it didn’t evolve back then, with 500 base stat, it’s a good competitive Pokemon. When it got an evolution in Gen II in Scizor, it doesn’t gain any stats, just has the Speed lowered and Attack and Defense raised. Its Bug/Flying type isn’t great defensively though. Its wings look a bit too small for it to fly.
In the anime, Tracey has a Scyther. It was an old Scyther that was driven out of its swarm by a younger one. Its voice is a lot higher-pitched and whinier than I’d thought.
Stat-wise, it has good Attack and Speed, making it a good physical sweeper. Because it can still evolve, Gen V’s new item Eviolite can give it 50% more Defense and Sp Defense, making it more defensive than its evolution Scizor, though Scizor still has better typing.
