Greetings all. I have been a GB. fan all my life, and I found some of the episodes from the original series, which I have taped off of USA and ABC back in the 80’s. Two of which, I do not know the title. One episode has the comic book character ‘Captain Steel’ where he flies out of the drawing pages and assumes that the Ghostbusters are bad guys, then ends up teaming up with them to stop his arch nemesis who also jumped out of the drawing page. The other episode I am not sure of, because I have only the last couple minutes of the episode, it’s where the GB’s are in some different realm and Egon gives this character ‘Herodemous’ his proton pac to cover their escape from that realm and return home. I am hearing talk of a Ghostbusters III in production. Is that true or false? Also where would I be able to find a complete list of every episode of the cartoons, including Extreme Ghostbusters? Any help given will be appreciated. Thanks so much
Hi There! 
I actually just watched that episode with Captain Steel the other night. But I don’t remember what the name of the episode was… I’m at work right now, when I get home I’ll check. Hopefully have an answer for you this afternoon.
As for GBIII… There has been talk about it for a long time now. And so far, all it’s been is talk.

This guide only covers the Real Ghostbusters and is pretty brief, but still might be handy. I’ve seen several comprehensive episode guides on the internet, so try a search and see what comes up.
The name of that Captain Steel episode you are asking about is… (drum roll please)… “Captain Steel Saves the Day.” :lol:
I’m not sure about the second episode you are talking about. I’ve got quite a few episodes that I haven’t watched yet, so if I happen to run across it, I’ll let you know.
Ya, I’ve done a few searches on episode lists and plot summaries, but have had varied success… Just keep looking. 
The second episode is Egon’s Ghost.
After getting zapped by Accident, Egon is rendered for all intents and purposes a ghost, and the guys must work quickly to ensure he isn’t lost permanently.
And the character is named Horonomus, or a variation of the theme.
And no, Ghostbusters 3 is not in production.
