7

The Ramon Zero saves Tony from the Cancer robots. That night Tony and Dr. Tanka are kidnapped by Zodiac operatives and taken to a remote island, Tony missing his arc reactor. Yinsen emerges and offers Tony to create weapons for Zodiac. Tony turns down the offer and unsuccessfully attempts to use a makeshift transceiver and motorboat. Using an improvised rocket launcher, Tony signals a flare. Yinsen returns Tony his arc reactor, while Ramon Zero (revealed to be Sakurai) destroys a Scorpio robot. (Source: Wikipedia)
