I have two smash bros 4 stories to tell.
So I was playing as one of my mains (Mewtwo) and the guy I was fighting was using Luigi. I kept launching him off of the stage but he wouldn't completely launch, so I charged my neutral B (Shadow Ball) and waited. He was falling through the air off of the platform, then tried to use his side B
And was about to shoot back onto the stage but I used my Shadow ball, hit him and he fell and died. We both then taunted each other with Mewtwo doing his poses and Luigi falling over, then I won xD
My other story is when I was playing as Yoshi. I was against a guy playing as Mario, and it was pretty funny. He grabbed me and threw me off of the stage, then hit me down perfectly and I died. He was then taunting me and I came back into the game with 1 stock left, he had 2 but was on like 140%, so I grabbed him with yoshi's tongue, then threw him off the stage and hit him down like he did to me. He then died. Then I taunted him and he left the game xD
