Have:charmander and archen. Want:pokemon as unique

[GraekTarmikos]

I have a level 1 charmander(with 2 dragon type attacks ) and a level 20 archen (fossil pokemon), i got both of them in wonder trades and i won't use them, i want something as unique as them, pokemons that are really rare or that you can only get one per game.
Thank you.

first, archen is not rare, you can get infinite plume fossils. two, you heard of breeding?

Charmander isn't too rare either - no more rare than froakie since everyone gets to choose one at the same point in the game.

If you want something equally rare, then you'd be looking at a starter pokemon, or bulbasaur or squirtle, since those are around the same obtainability in the game.

If you want any of the following, I can breed them (no need to give me anything in return) : Charmander, Bulbasaur, Squirtle.

First of all, thank you for the answers. Yes, i know archen is not unique, but i'm not familiar with the new generations and i have to search online all the pokemons i get to know if they are rare or not, people said fossils were really hard to get, so i assumed it was at least rare. I am not asking any super rare pokemon, i just want a pokemon that is in the same level of rarity. Before pokemon Y, the only pokemon i played was FireRed and i played it a lot. I dont know any of these new pokemons and i still dont know their value. Sorry for that. I dont want a rare pokemon for my charmander either, i would replace my braixen with it if he was in a higher level. I wanted a pokemon that could replace one in my team (tyrunt, wartortle, snorlax, hippopotas,braixen and roselia.). Around the same level (25-30). I got charmander in a wonder trade and i just dont want to trade it for a commom level 5 random pokemon. Sorry if i got somebody angry for my ignorance, but i'm still adapting.
