Okurr so if you remember Starstreaker, I added to the lore.

So Starstreaker was the first Demonian, and whenever they died, their spark shattered into multiple pieces, giving birth to four new beings.

Silverbeam, a Minicon who can no longer transform because his T-Cog was damaged beyond repair

Skytremor, who was so desperate to deem himself worthy as a Decepticon that he switched out his parts to look like a Seeker instead of a Demonian

Blitzfire, a medic specifically for the Demonians since no other Decepticon knows their anatomy like him

And Hardwire, a possum-like creature who is Blitzfire's pet and assistant who can reach crevices he cannot.

Their DNA is considered pure due to their direct relation to Starstreaker, thought they aren't much different from the regular Demonians.
