Oculon?

[Rerednaw]

He's mentioned in Champions Universe and in Conquerors', Villains and Crooks, but there isn't a write up for him.

In CKC, his entry is in boldface indicating a character sheet, but unfortunately he isn't.

Where can I find his 5E stats?

[DrSavant]

He was first listed in Enemies 2, page 19. Although that is a write-up for the pre 4th and 5th edition you might be able to translate him.

[Monolith]

His stats will be in the VIPER sourcebook, coming soon to a game store near you. :)

Oculon works for VIPER, as noted in Champions Universe. You'll see his writeup in the VIPER Sourcebook when it comes out later this year.
