Universe 12: Trunks's new friend, created by his most hated enemy! is the tenth chapter of Dragon Ball Multiverse and the second special chapter. This story focuses on the backstory of Universe 12 on which Trunks rediscovers Android 16.
Trunks enters Dr. Gero's laboratory and opens a capsule which contains a deactivated Android 16. A few days later, Bulma reactivates him. Trunks then calls out Android 16's name and he responds to it. Trunks tells the news of Gokū's death. He then asks Android 16 if he would protect the life of Earth and the survivors living on it. Trunks then transforms into a Super Saiyan and tells Android 16 that he's stronger than him.
Trunks then reverts and makes a deal with Android 16. Bulma will repair him, in exchange of his word to protect life. Android 16 accepts the offer. Trunks also stated that he will destroy Android 16 if he would harm any humans, which he also accepts. The chapter ends with Android 16 being rebuilt.
