Jinzouningen 13-gou

人造人間13号

Android #13 is the thirteenth android in the series constructed by Dr. Gero. He looks and (in the English dub) sounds like a redneck. He was built alongside androids #14 and #15 with the mission of killing Goku. He "evolved" into the significantly more powerful Super Android #13 after absorbing key components from the defeated Androids #14 and #15. He was killed by Super Saiyan Goku, who was powered by a Spirit Bomb. The manga only mentions that an Android #13 was created, deemed a failure, and subsequently destroyed. 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.
