This animated series is a continuation, a sequel of sorts, to The Real Ghostbusters (1986). It picks up some seven-years later after the original 'Ghostbusters' disband/break-up, supposedly due to lack of paranormal activity. All the ghosts & goblins simply up and vanish. Suddenly, when strange things/creatures start surfacing again in New York City 1997, 'Egon' recruits an all-new team of 'Ghostbusters' comprised mostly of his best physics class, university students. One of the best episodes was the return of the original "Real Ghostbusters." They appeared in a two-part episode fully dressed in their old-school jumpsuits and carrying their traditional proton packs. Except this time their true age began to show. They began to act/move a little bit slower.
During development of the show, a deal was made with toy company Trendmasters to produce a tie-in toy line. Trendmasters really wanted the show to be titled 'Super Ghostbusters', but the producers found that title a bit too 'soft' and came up with the more edgy sounding 'Extreme Ghostbusters'.
