Heartwarming: Ben 10
- The episode "Ken 10" was made of this, but especially when Ben stops Devlin from leaving and instead of throwing him in the Null Void like he expects, asks him to stay and become a part of the family, and Devlin, of course, accepts.
- How did anyone forget "Secrets of the Omnitrix"? Ben breaking down into tears, and then embracing his cousin Gwen, after thinking she was dead. If you've watched the series you'll know it takes a lot to make Ben cry.
