Klonoa could be a very safe bet since Namco has only one rep right now for Smash. I don't know if Klonoa has been on Nintendo consoles because I recall he was on the Playstation consoles. The last game I ever saw Klonoa from my memory was Namco X Capcom. If he was to get in Smash, they may use his VA from NxC.
Beware the Dark Wolf once more!
