IRIA was adapted into a Japan-only video game for the Super Famicom called Hyper Iria, although it does not seem to follow the storyline of the OVA very closely.

The film Zeiram was followed by a live-action sequel, Zeiram 2, as well as an OVA prequel miniseries called Iria: Zeiram the Animation and two videogames, Hyper Iria and Zeiram Zone.
