Sub to Error!
Void is owned by Starbreak, and was allowed to be added to the series as an unofficial collab between the two.
Canonically, Void is aroace and uses he/him pronouns.
If Void had an aesthetic, it would be spacecore.
Canonically in the series, Void is good friends with Jay.
He is described as narcissistic, egotistical and... just as famous as the others.
While deemed not canon to Void's official lore, Void being placed in Cyber Space is canon to the lore of the web series. While he doesn't appear often, he does still appear. It is believed that this Void may be a carbon copy, but who knows.
The official FNF Vs Void mod can be found here.
Void is voiced by Starbreak. (Or... planned to be.)
