Johan Hex has shown up in movies, animated shorts, live action tv series, and guest characters in animated shows.
What’s your review on the version of Hex you saw??
From my knowledge I saw him in BTAS, Justice League Unlimited, and Legends of tomorrow. There’s also a very gritty Hex short that was released as an intro to one of them animated movies if you can find it. That short is the best representation of the character in my opinion. Linda Hamilton (original Sarah Connor from Terminator 1 & 2) does voice work there.
