Dragon Ball Z: The Future Chronicles (Audio Drama Series)
Caleb Wheelock for Future Android 17
Future Android 17, alongside his sister, is extremely sociopathic and cruel, taking joy in killing and destruction. According to them, the two sibling androids' personalities is the direct result of Dr. Gero's attempts at programming them to hate humans as part of his bid to conquer the world. Future 17 has always been around with and cared about absolutely nothing but his sister throughout his life, they were never separated since their activation, and are always seen together. They are known to be extremely unfair in combat, helping his sister when she becomes overwhelmed, and not letting their opponents heal or escape alive when incapacitated, wanting to kill them very quickly.

Well, it seems like that was the last human. What city should we go to next? (Rather carefree, show how little he cares about human life)
Well look at that sis! Seems like we have a welcoming party on our hands. (The Z-Fighters have arrived, sound a little excited at first but slowly drift into a more unamused and sadistic tone)
If you all are done with the chatter, would you mind telling me where Son Goku is? We have some...Business with him. (Sound a little annoyed at first)
