Nero and Bulma trained together while Drake took a tour of this planet earth. Bulma was happy that they would have a son so she made Nero fill her every night. The day that Dr. Gero and android 19 appeared Goku and Vegeta managed to obtain Super Saiyan. Nero helped Bulma awaken her Super Saiyan power as well. The Z fighters, Nero and Bulma landed in front of Dr. Gero and android 19.
Vegeta turned into Super Saiyan and took out android 19 with a Ki blast and Gero fled to activate androids 17 and 18. Nero led them to Gero's lab and they saw Gero getting murdered by 17 and 18. Everyone except Nero were shocked. Everything went like in the regular timeline except that after everyone was beaten Nero told Bulma and Drake to watch how it's done. 18 smirked expecting him to be weak like the others.
Nero got into his fighting stance and said, "Come at me blonde." 18's smirk went away and she rushed at Nero. She threw punches, kicks and Ki blast at him but all of her moves missed not even giving him a scratch. "Is that all you got for me? How pitiful."
Nero this time let 18 land a punch on his face. 18 smiled and thought she finally wiped that annoying guys smile off his face. Nero grabbed her hand and slammed her into the ground. He then grabbed her head and held her up so 17 could see her face in pain as he applied pressure to her head. "Scream for him bítch."
18 screamed out and 17 took the bait. He flew at Nero and yelled, "Let go of her you monster!" When 17 got close enough Nero threw 18 away and grabbed 17 by his fist he then flipped over 17 and due to 17 moving so fast his arm made a cracking sound. Nero tore 17's arm off and threw it to the ground. 17 screamed from the pain while Nero laughed.
"Fun time is over androids time to die." In Nero's hand a small purple sphere appeared. "Hakai!" The small sphere shot at 17 fast. 16 came out of nowhere and sacrificed himself to save 17.
Nero grinned evilly and looked at 17 and 18 who were looking at him with horror. "Go! Run and hide. Next time I won't let you live." They both fly away as fast as they can and Nero looks over to the direction of a new Ki signature. "Welcome Cell to the game."
