Hey, remember that there are gonna be two new Robot Masters that are debuting in Mega Man Powered Up, a remake of the first Mega Man game (which only had six Robot Masters rather than the traditional eight since then)? Pictured here is when they were shrouded in mystery in the official Japanese trailer.

I theorised that this one is a clock Robot Master, since his head is shaped like an alarm clock. The clock-type level shown later in the trailer would logically be his stage.

This robot, however, has an ambiguous appearance, but I theorised that he could have connections to the oil refinary level shown in the first batch of screenshots.
Well, recently these Robot Masters have been fully revealed in all their glory! But not in the way you expect...

You can barely see them on the label-thing with the original MM1 Robot Masters.
Further judgement will be held when bigger and more clearer pictures of them are shown.
