Goku, Yakon and others in “Unfinished Business”

Why'd I have to get this guy? Sure, he's big. But he kinda looks dumb ta me.

Huh?

I know that monster. I know who he is. His name is Yakon.

You've met him before?

That's right. He is one of the most feared creatures in the universe and he is extremely strong. I don't think Goku will be able to beat him on his own.
