Ultimate Grey Matter
Ultimate grey matter was the ultimatrix's ultimate galvan. It's possible that ultimate grey matter would resemble ultimate albedo. Ultimate albedo's limbs appear to have grown larger in each appearance. In malgax attacks, ultimate albedo's hovercraft can be seen emitting red energy seen as rings. The subtitles refer to ultimate albedo as ultimate grey matter.
Ultimate grey matter being the evolved form of a galvan, ultimate greymatter is even smarter than his regular form (though ironically not as smart as azmuth). He additionally gains psychic.
