E is for Evolution
And we're not talking human evolution here, people.
Because there's a better kind. You heard me. POKEMON! (Yes, I'm still slightly a nerdy kid at heart ) And what do Pokemon do? They evolve!
A neighbor kid of mine got me into Pokemon back in 1998; we started trading cards and he let me and my little brother borrow his Gameboy for a couple weeks, just so we could play Pokemon Yellow. (Our parents = dinosaurs and didn't believe in video games…yet XD) Bro and I would sit at the kitchen table, taking turns beating up Gym Leaders, catching Pokemon, and evolving them.
We somehow conned our parents into getting us Gameboys of our own, as well as the other Pokemon games. Gold was my favorite. My teams usually consisted of all fire Pokemon…because who doesn't love cute little Arcanine? Or perhaps Ponyta? Or my favorite: Ninetails!

Ninetails
Either that, or I'd have an entire team of Eevees, evolved to a different stage. Or heck, as long as the Pokemon resembled dogs, cats, foxes, or wolves? I was game!

Houndoom, anyone?
(^ Maybe why I like hellhounds so much? The world will never know!)
By the way, the worst evolution? The stage where your bug Pokemon turns into a freakin' cocoon and can use one move: Harden. And it doesn't even do any damage to your opponent! LOL Whyyy would you make a fighting monster turn into a cocoon in the first place? I never raise bug Pokemon, just so you know.
My trusty Ninetails will kick that cocoon bug's butt, any day!
