Android -17

-17 is an android based on Dr.Gero's 17th creation. Dr.Flappe and Dr.Wheelo created this together to rival Dr. Gero's android vendetta against Goku. Dr.Flappe first thought of the idea to betray Gero when Gero took full credit for the creation of Android 8. So he started working to find someone to help him. Then, on his search, met Dr.Wheelo, apparently someone from the future who escaped Hell. Dr.Wheelo told him that he watched the fight with the androids in while in hell and together made -17. -17 Then was based heavily on Android 17, but modified to be the opposite. He was design to help Goku instead of destroy him, but this failed and Android -17 just came for revenge and started his plans. Dr.Wheelo had already put the memories of when he was watching buu saga and everything. So while both his makers died of old age, he already knew that he couldn't go at the Z-fighters head first. So he divised a plan.
