What are your opinions on overused Pokémon.

My personal opinion is that with every underused Pokémon, a overused Pokémon can come. And with underused I don't mean like a cool Pokémon, just not many times used like Muk, But I mean like Voltorb/Electrode. Hanada let his main person Tracey catch a Charmander, the most overused of them all. But he also caught a Voltorb, and to tell you the truth I never saw him in a fic.

And also what bugs me, that many people think Pokémon used by Brock, Misty, Ash, Jessie, James and May are overused, just because they have it. I'd like to see that that's not true. A real over-used Pokémon is that it appears in a lot of fics.
