Not to mention, wasn't Garlen originally a pilot for the Biskarsh? (Please correct me if I'm wrong, I remember hearing that from somewhere but I forget where)
Also I don't think Garlen has an IQ of 300...
But that's just my 2 cents on this..
OH ANOTHER SIMILARITY. THEY BOTH RIDE AROUND IN FLYING MACHINE THINGS THAT THEY PILOT
Only I think Garlen uses.. spikers as main weapons and Robotnik... missiles. . .? From the flying machines I mean, please correct if wrong, It's been WAY too long since I've last played a Klonoa or Sonic game. . .
EDIT: Is Garlen a slight reference to Inspector Gadget's Dr. Claw too? I mean, they both have a claw for a hand and I don't think it was ever mentioned HOW he lost said hand. . . Not to mention they're both similarly cunning with their plots, or is it just me?
