There are 4 Robocop movies (one is the new one, the others are from 1987–1993). There were also two live action television series, and two animated series.
Nuke was a plot element from Robocop 2. Because it was instantly addictive and had a high fatality rate, it is best compared to Crack, which was the drug that modeled on. However, it is an exaggerated embellishment. No drug matches Nuke.
