If you are totaly stuck at mega emperor and have no have no hope what so evver of beatin him here is the ultimate strategy to do just that.

first u must equip Rokusho with the right arm part hand flash. then u must change his head par with head shuttter. then do the same with your other medabots but be crefull to have a female medabot who has either apealsound, sidemufler, silencer or and if it works the head part reflect mirror.that should about do it but remember that they always use the medaforce and alot two. Also you must have a part on every one of your medabots that DOES DAMAGE OR YOUR DEAD MEAT. Have fun.....
