Megemerge is the Techique of the Biometal.

Biometal uses the M.E.G.A. (Meta-Encapsulated Granule Awareness) System (R.O.C.Kシステム? R.O.C.K. (Rebirth of Crystallized Knowledge) System), and can Megamerge (ロックオン? R.O.C.K. ON) with a Chosen One (also referred to as a Biomatch). In a Megamerge, the Biometal becomes the user's living armor, and gives its user the abilities of whom it is based upon, becoming a Mega Man (ロックマン? Rockman). Biometals are generally referred to using an initial, e.g. Model Z (Zero), and generally titled as Mega Man Model _ (Model initial here) during Megamerge.

Biomatches are individuals destined for a particular Biometal. Most Biomatches tend to have similar personalities to the Biometals they are destined to use, aside from Model O and Model W, whom have shown no visible consciousness. Only the Biomatches can hear the voices of the Biometals, especially when the Biometal urges either Grey or Ashe to Megamerge. Only a few of the Biometal have shown to be compatible with more than one individual, as in the case with Models Z, X, A and W, yet Vent and Aile are able to utilize other Biometals through Model X while Grey and Ashe can copy their Mega Man forms using Model A's A-Trans ability.

The fusion between Chosen One and Biometal appears to occur at the genetic level, as Model A's A-Trans is able to copy the exact form of a transformed Mega Man down to the subject's species and gender. The Chosen One retains full control of his/her actions, but the Biometal can still speak independently and may cancel the transformation at will.
