Major Scrapped Spinoff called “At Crossroads End”
Shows Trolloner has various linked Vessels.
Bloodsteel:
Bloodsteel came from a clone (Trolloner can create clones from his own body) that absorbed too much cosmic energy resulting in expelling all malevolence and becoming sentient. Proceeding to help humanity for 500 years until most Universes were wiped out. Eventually he came in contact with Trolloner again in the fractured Nullsphere where Trolloner reinserted his energy creating Bloodsteel.
Jepordef:
On an alternate earth few humans came across a dormant Malevolent Heart. They formed a whole religion on awakening the heart, proceeding to sacrifice several people in the name of “Purify and Cleansing” ; eventually one sacrificial lamb that was a human girl managed to activate it by sacrificing her pain for her “Mind”. Creating Jepordef.
Ganoshker:
In a Alternate planet a ruler of near extinct surviving species gave his people’s lives to conquer all places
During the final era of the Black Sun in his name.Jawless:
A human tortured by Trolloner during the sixth cycle of the Black Sun. Eventually this human mutated and warped in the shape of Trolloner. Still he retains his human heart.

From all of them. I would say the worst to have an encounter with is bloodsteel.
Even Trolloner struggles trying to keep control over him.
