Eikelmann, I care - lol
I've been playing Fox for a few years and recently I have begun rapidly studying and playing more Mewtwo.
I just learned that you used to play Mewtwo when I saw a post on the Mewtwo boards where you asked to have a video of you studied, and Taj complemented your fundamentals.
You said in that post that you used to main Ganon - so I guess we all know what happened after a short while... XD
I don't really think I've fully learned to play the game though, and I'm continuing to practice with Fox, and I can't see myself playing a tournament match as Mewtwo for many moons.
Also that very first paragraph in your most recent post happens to be my roommate who switched from Link to Falco.
So I have seen that first hand, and it sucks.
My advice is: decide what your smash goal is and stick to it. If it's be the best, pick a character who's won a major. Fox, Falco, Marth, Jiggs, Shiek, Peach. If you have a more specific goal - to style in a certain way, or push a certain character, do that.
Personally I don't think Bowser is great character to push because he's been pushed before - so the only thing you really get out of it is a party trick. Being good with Bowser for a laugh is kind of the wrong way about it.
Pick a character who has some kind of promise - someone who's performed very well within the last few years. Yoshi and Pikachu would be good examples, though pika isn't very low tier. Maybe not a character who's already done well, but someone who could. A character with tech that's never been perfected or executed regularly.
But to be honest if you're hoping you'll discover that this character belongs with Fox, or even just falcon ICs Pika and Ganon... you're likely to be disappointed.
tl;dr
If you want to be the best at smash, don't pick a low tier. If you wanna invest a bunch of time into a party trick, go ahead- but going so far down the list as bowser is probably a bad idea. Hell, you're probably better off with pichu.
