Dragons? As in multiple? That's really cool. In my world, there's only the one. His name's Shenron, and I kinda owe him my life. ...A couple times over really.

[Yeah, Krillin hasn't heard of the royal dragons yet, just the dragon-like people that gave him awkward flashbacks of Tamborine...]

Don't think Shenron really... exists in the physical realm though, if that makes any sense at all.
