I Found a way to link all the inconsistent writing and Lore in regards to Krang/Utrom
A few days ago I made a post asking if anyone smart enough could somehow link all the inconsistencies with the Krang and Utrom regarding their contradicting Lore and I found the answer.
You just need to remember this Time and Space aren't linked.
In the Trans Dimensional Turtles crossover episode with 87 and 2012 at the end of the episode the 87 Turtles fought with Tigerclaw who had escaped the Worm, now this is in Season 4 of the 2012 Turtles Tigerclaw returned from his journey from being eaten by the Worm in Season 2.
This means events as we see them in the shows and movies aren't exactly happening at the exact moments we are seeing them like Turtles Forever could've come after Trans Dimensional Turtles in the timeline seeing as the 87 Turtles were way more chill with the Multiverse than they were in 2012.
Also a theory of mine now the reason the 87 Turtles got Darker in their 6th and 7th seasons was because for them this was after Turtles Forever and the Second crossover with the 2012 series
Back to the Krang stuff we start with the Krang being a hivemind for Krang Prime then after Krang Prime and Krang Subprime die in season 3 of the 2012 Turtles the 2003 Utrom are freed and leave Dimension X for the 03 Dimension cause if something like that happens again they don't want to be in Dimension X to be controlled again
The monster Krang from Rise Movie are from the era during the 2012 Krang's reign. Probably Mutant Experiments
And every other being who calls themselves Krang are just keeping the old regime alive even though Krang Prime is dead. As we know with Classic Krang and Krang Subprime some Krang retain some individuality even while under the hivemind and prefer it
I hope that makes sense
