It's not that he ***** everything, he just has the advantage in some matches, I think the ones originally posted in the thread were pretty good like dk and ddd, however after talking to a bunch of snakes they all agree pit is a bad match for them. Other 50/50's have equal good points and bad points about them.
The reason I didn't take stage into account was because of characters like zero suit - who when placed on a stage like lylat cruise really changes the match drastically in pits favor.
I was really iffy on Marth as well, any Marth knows that if you over B pit, and up B anything else that pit does he's almost powerless in the match. It's a constant uphill battle.
Slight changes like pikachu is a difference of opinion - most of pikachu's moves cause some sort of stun or knockback which is bad for Pit's placement. Coupled with the clanging of thunderjolt and arrows, and his down smash that you have to come from above on, or wait out make him a formidable opponent against pit. Also, if played correctly on the edge the gimpablilty is not there.
Dk and Ike - This is pretty much played the same way. If you use a abundance of arrows dk and ike fall easily because there is nothing they can do, except trying to stay close to you. If you choose to fight the match, it becomes more in favor of dk and ike. No moves Pit has comes anywhere close to the damage potential and range of both these characters.
The only move I can't get around for MK is his tornado, If you stay close and time your moves you can beat him, also remember he has to approach from the front except on final d. Just stick moves out and you'll rack up damage. (Most everyone will probably disagree with me, this match takes time to learn.)
The fat characters and snake can be chain grabbed making the matches about even.
Just this weekend at Critical Hit 4.5 I changed my mind about Falco's matchup. His chain grab is really damaging to Pit, and you can't sit and range him because he'll range you back. You also cannot up B push Falco away out of the grab like you can to DDD. In general I think it is a constant uphill battle for Pit.
