Suggested by Sonic Grimlock is a powerful fighter and of course he does have his dino mode but at the end of the day I don’t see him being fast enough to keep up with Ridley. At max speed Ridley was able to keep up with the Blue Falcon and his attack power is considerable as well. I don’t see this being a super one sided fight but at the same time I don’t see any avenues for victory for Grimlock. Ridley wins.
