Proto-Machina can be thought of as having no Class at that particular time. This occurs during a certain set of circumstances where expedience is needed for Machina development. In these situations, the Machina are prevented from developing more than the bare essentials so their development is faster, but otherwise develop from Category 1 through to Category 3 as normal. This can be ordered by a Queen whose situation necessitates new forces as soon as possible, or may be triggered by [[Outbreak Protocol]]. Once the situation improves, the Proto-Machina will be released from the restrictions and allowed to develop the equipment she would naturally have.
