Bert took a round trip with his Nicknames. Coming from the Melee scene where his nickname was "Bert", he first stuck with it for SSB64. Then, after a short period of inactivity, he resurfaced as his alt "Minachan", which was his way to reinvent himself as a Falcon main. He was identified as Bert very quickly though. He started calling himself "Berber" after moving to Bonn (which is what his local non-Smash friends there still call him), but everyone knew that wouldn't stick, so he gave up and went back to "Bert".
