Biography
With the return of both Super 17 and Super 18 in the future, Trunks was Earths only line of defense but was not match for the Androids combined power.

He soon returned home where his mother Bulma suggested using the remaining parts of Android 16 to create a new Android to help Trunks combat the two Super Androids. They soon created the new Android, Android 30, being sure to give him a human heart so he would feel compassion and emotion.

With their combined forces they were evenly matched with the two Super Androids. But Bulma appeared with a paralyzing device, paralyzing Super 18, letting both Future Trunks and Android 30 attack Super 17 at the same time, and then doing the same to Super 18.

Android 30 soon was charged with being partners with Future Trunks should any new threat arise to Earth
