Jinzouningen 13-gou

Android #13 is the thirteenth android in the series of androids built by Dr. Gero. He resembles and sounds like a redneck. He was built along with androids #14 and #15 with the mission of killing Goku. He "evolved" into the much more powerful Super Android #13 after absorbing key components from the defeated Androids #14 and #15. He was killed by Super Saiyan Goku fueled by a Spirit bomb. Only the fact that an Android #13 was created, but deemed a failure and subsequently destroyed was mentioned in the manga. However, since Dr. Gero's computer was still building 13 while 17 and 18 were active, it can be assumed that he was not entirely destroyed but stored away as a back-up plan.
