EM Wave Change

An EM Wave Change, known as a Denpa Henkan (電波変換) in Japan, is performed when an EM being merges with a human in the Mega Man Star Force series. This creates a more powerful EM being that is able to interact with both other EM beings and regular humans.

Characteristics
During EM Wave Change, the human becomes part of the Wave World, and is thus subject to the same rules as other EM beings. The EM being is then able to give its powers to its compatible human, and the human is able to use Battle Cards as actual weapons.

Fusion
During an EM Wave Change, the EM body and human are combined into one body with the consciousness of both, but it appears that only one of them control body, or at least part of it, as seen with Geo Stelar controlling his body while Omega-Xis controls the arm. Some EM beings, mostly FM-ians, will try to take their human partner as a host body, and attempt to subdue their human's consciousness completely, though this process can take time even if their bodies have fused (and it sometimes just freezes if the two are resisting the fusion)

Solitary
In Mega Man Star Force 2 and during the Tribe season of the Mega Man Star Force anime, Solo is shown being able to EM Wave Change without the aid of an EM being from which to borrow his power. Through simple willpower, and the effects of an "ancient Star Carrier," this allows Solo to become the EM being Rogue. However, he gains his own EM body named Laplace in Mega Man Star Force 3. Laplace, however, does not aid in Solo's transformation, he becomes a very powerful sword.

Transcoding
During the third game, the method of Wave Changing was changed. Because EM beings were converted into Wizards due to the Hunter-VG, they were unable to EM Wave Change in the normal way. Instead, Wizards could only fuse with their human counterpart using the Transcode, which instead of normal EM Waves, used the Satellite Server, which WAZA has built, and has registered every human who is able to EM Wave Change in a project known as Project-TC. Transcode resembles Cross Fusion more than EM Wave Change, because the Transcode uses data, rather than simple EM waves.

History
In the first and second game, the protagonists Geo Stelar and Omega-Xis have to find spacial distortions (signified by orange portals named waveholes) to pulse in and become Mega Man. It is not shown whether other willing characters have the same condition, although some characters appear to be able to Wave Change in any location when forced or by using an ancient Star Carrier from Mu.

In the anime and manga, however, any EM being and their compatible human can EM Wave Change by shouting the phrase "EM Wave Change! [Name], On-Air!" in a similar way to the Megamerge technique.

In the third game, Geo (and all others who have the ability) can Wave Change in any area, however the method has changed. Upon Wave Changing for the first time in the game, the Wave Changed being is assigned a "Transcode" and an ID number (Mega Man's is 003), as well with a Code Name (For Mega Man in the Japanese game, the Code Name was "Shooting Star") that is assigned from the Satella Police. After that, the user must shout, "Transcode! (name of Wave Change form)!" in order to transform. Accessing the Wave Road is done through a Wave Station, which in previous games was done by wave changing in a wavehole.

Unregistered, and thus illegal Wave Changes still use the old phrase, however.

Trivia

 * EM Wave Change is similar to the Cross Fusion in the MegaMan NT Warrior anime, and the background used when a character is doing an EM Wave Change in the anime is the same as the Rockman.EXE Stream background for Cross Fusion. The major difference is EM Wave Change doesn't shatter on emblem damage like Cross Fusion.
 * Another similarity EM Wave Change has is the sync rating. Once, Geo's mind was in turmoil when Cygnus, using Tom Dubious' body, told Geo that Omega-Xis killed his father. This caused Geo's EM Wave Change to deteriorate. This is similar to when Lan got into an argument with MegaMan and couldn't maintain the Cross Fusion due to low Sync ratings.
