Beast Out

Beast Out is when MegaMan.EXE absorbs a Cybeast, either Falzar which is a large hawk/phoenix or Gregar a wolf to become Falzar/Gregar Beast MegaMan you can see these forms in the games MegaMan Battle Network 6 Cybeast Falzar/Gregar. Also MegaMan can do cross form (it's similar to Double Soul but longer) with beast out.
