Ever had that one boss you could never beat, or took ages to do so? Here's the place to rant about them, and maybe tell an epic tale of how you overcame them (if you eventually did)! For me, the nightmare was Tabuu, that final blue death angel boss from the SSBB Story Mode. This was back before I got into competitive Smash, so I had no idea how to avoid his instakill attacks properly. I spent half a day trying to beat him and eventually got lucky after using a bunch of heavy characters that could survive the damage/knockback Tabuu inflicted. Many years later I came back with a vengeance and thrashed him. It felt good.
