"The Evil Truce" (逃げろ！！１８号 Nigero!! Jūhachi-Gō, lit. "Run Away!! No. 18") is the one hundred eighty sixth chapter of Dragon Ball Z and the three hundred eightieth overall chapter of the Dragon Ball manga.
Cell is still cursing the fact that he hasn't reached his Perfect Form, but Vegeta floats down to him, intrigued. Vegeta asks if Cell meant what he said that if he obtained his Perfect Form, Cell could defeat him. Cell confirms it, saying the computer told him that, in his Perfect Form, his power, speed, skill, and mental strength would be perfect. At this, Vegeta kicks Cell away again.
Android 18 believes that Vegeta might have only pretended to be weak when they fought prviously, but Android 16 states he'd have no reason to do that, and that something changed in the last few days. Krillin, meanwhile is getting closer, and finally gets within the 10 meter range. However, seeing Android 18, Krillin struggles to make himself push the button.
Vegeta walks over to the rising Cell, asking him if even after how weak he is now, if turning Perfect would make him strong enough to beat him. Cell confirms it once again. Future Trunks starts to worry that his father might actually be considering letting Cell get his Perfect Form.
Meanwhile, Krillin continues to struggle with the thought of shutting down Android 18, and finally can't bring himself to do it, dropping the Shut Down Remote. Android 18 reacts with shock, seeing the dropped remote, and wondering how Krillin could have gotten his hands on it, considering Android 17 crushed the one Dr. Gero had.
Cell continues to goad Vegeta, knowing his Saiyan pride will want to fight Cell at his best, knowing Vegeta wants to see how powerful his Perfect Form is. Vegeta finally agrees, telling Cell to go obtain his Perfect Form, then come back to fight. As Cell goes to leave, however, Trunks cuts him off.
Krillin apologizes to Bulma for all the effort she put into the remote, but crushes it under his boot, much to Android 18's shock. Cell yells at Vegeta to do something about Trunks, but then spots Android 18, realizing his Perfect Form is now within his reach!
