Is Violengiguar the King of the Undergrid just like he is in ICRT?
Depends on the universe in question, as in some universes he did become King of the Undergrid, and in other universes he didn't

Is the GI Joe/Transformers crossover still happening in Suleforger continuity?
Indeed it is, it should be out in the foreseeable future
If Cipher ever went to Earth, what would her Earth mode be?
Universes where their Cipher ends up travelling to modern day Earth and adopt an Earth mode usually adopt large Aircraft as their alt modes.
What particular type of Earth Aircraft differs between universes where this happens in
Where is the Maladroid Enclave located in the Milky Way galaxy?
Southeast of the Decepticon Hegemony of Chaar(aka the piece of Decepticon territory near Solstar Order Space) and northeast of the area of Mercenary Consortium space next to the Chaarian Hegemony
(I’ll probably add it to the galaxy map at somepoint)
Will Cipher ever appear in stories the main continuity? Or just in Swtorformers whilst just being a character that exist in the main continuity
Probably at somepoint, most likely I shall perhaps make her appear in Spotlight Violengiguar depending on the final plot I’m planning, though that isn’t a garentee
Are Universe in Suleforger continuity have infinite planes of existence? Or are they have just 17 Spatial Dimensions?
Way more then that, you see when we say 17D and 44D in Suleforger continuity, we don't refer to Spatial dimensions but rather Daia Stacks, with universe containing anywhere between 17-44 Daia Stacks, with each stack having R>F over the lower stack
Each stack containing infinite planes of existence with R>F, each plane of existence is made up of infinite layers which also have R>F over one another and each layer contains a transfinite amount of spatial dimensions So to answer your question, defiantly more then what you said(I know it's a bit confusing for us to call it 17D when it isn't referring to spatial dimensions, in further productions we will be referring to it as 17DS)
So Cipher exists in the main universe now? Does that mean that the other swtorformers exsist in the main universe as well or not?
As of now, no the others don’t exist in the main continuity universe , they currently exist only in the swtorformers universe and all of its alternate timelines
(If we were to bring another member of the Swtorformers caste into the main continuity universe, it would be Scree, Furyslasher and Shadowslasher)
Will you ever do a Shattered Glass Series?
Not in the foreseeable future, though if I did make content about Shattered Glass it would be a SG Novella rather than a full series
(I think I did write a oneshot in my notebook, though I don’t have plans for releasing it)
