What kind of sorcery is this?!

Now I remember myself in a serious battle againts the Saiyans, when Vegetta screamed 'IT'S OVER 9000!!' as they approached me.... To make it short, they were then forced to seek Pandaren's help to knock me unconscious, which is the most they could do. Then the last thing I heard was 'I BRING PANDA MONIUM!!' Then, a moment after being respawned I got puzzled, realizing part of my memory is gone permanently after the match with the STRONGEST GODDAMN BREWER. I've tried hard to remember the password to my previous blog, but its worthless! This is the only logic explanation for the memory failure.
