according to the Armada comics when working all together they might be universal(+)?How strong are those miniature bastards anyway?
I had kinda dismissed it as flowery language but then they successfully blow a hole through Unicron later in the comic and drive him out of the universe at least for a time so
it may very well be legit
albeit that was minicons of two universes
I'm not really sure about the animated version, I know they created a "Unicron of Light" to fight him in that world and I think in Energon/Superlink Unicron's body ends up being used to create a new universe or something? @Crimson Dragoon would know that better than me
individually they arent strong at all though
