It was at this time that years of experimenting with bees paid off and he discovered that he could communicate with them through his music, thus the costume and replacing his henchmen with bees.
The Maestro would return, changing his costume and some of his m.o., becoming an almost grotesque figure. His music could enslave others and he wore a dark suit, cloak and top hat (retaining an antenna to counteract Lighting's powers).
