From DengekiOnline. What we have here this time is Aqua Armor or Saito.bat assumptions.
Battle in Network Mode from Battle Network Rockman EXE
It clearly isn't Aqua Armor or Saito.bat. It's just a thing the game would do against another Rockman in Netbattle just for fun. You could say all Players have it and can't see it. There's no power boosts at all either.
