Sadly, I lacked a recorder back then, so I cannot proved it actually happened. Plus, I get worse when I play while recording because my recorder can't handle things at a good speed when too many things are going on.
Me and my SUPER ULTRA SKILLED bro were brawling it out. I was MetaKnight and he was freaking Zelda. (Din's fire abuser! ARRRG!)
I beat him like 1 in 10 matches, and this one seemed like that 1. We were on our last stock and I was at about 30% and he was hovering at the 300 mark. So, I was going to use one last smash to finish him off when he smacked a party ball. It flung into the air and released several bombs. They took the hit and sent both of us flying into the sky. It was just basicly who ever lost the stock first. He got a screen K.O, but I got a Star K.O. Needless to say, I lost the match because of a freaking terrorist attack for the MarioVerse.
