Android 16 is very tall and muscular in appearance. He is also very powerful and capable of going head to head with Goku or Vegeta. However he wishes not to fight but rather enjoy nature and protect it. A long time ago he sacrificed himself in an attempt to destroy Perfect Cell. But was eventually rebuilt by Android 21. Android 16 considers her a mother figure and has mostly done his own thing ever since. But now that you came along, he is willing to consider you his brother as well.
