Aw, c'mon. The "Just because you've never heard of players doesn't mean they suck" topic gets three pages, but this can't even get another post?
I can think of one time, specifically. I just about knew I wasn't going to win, but I was definately humilated after it.
My Ness sucked. Curious why, I find my way into the Ness boards. I read some topics, watched a couple videos, and while they helped, they didn't cure my problem. So I decide to take it to the next level: getting personal help. I looked around the boards, trying to find somebody that knew what they were talking about. Found one...Earthbound360. I send a PM off his way asking for assistence. We exchanged messages for a couple of days, until I finally got bold enough to ask him for an exam. EB360 agreed he'd see what my Ness was like. We finally fight each other online, and for about 3/4 of the matches, I could somewhat hold my own. But this one time...well, it didn't work out that way.
It was a Ness duo. FD, no items, the usual. To this day, I'm...really not sure what happened. I mean, it was utter destruction. Can't even remember if I got him down a single stock or not. Needless to say, he crushed me, and did it in Replay-saving time. For the next 15 seconds or so, I just watched the TV, stunned. That's the *only* time somebody's 4-stocked me in less than 3 minutes.
As terribly not-interesting as the story was, it was crucial to my Ness career...it only made me want to practice as him more. My only regret was that I didn't save the replay. It would be aptly titled, "What not to do when playing as Ness."
