Suggested by Sonic Kay has martial arts training and some good sword skills. He even has mild elemental abilities like his fire ball. Those aren’t enough to impress Sonic, but at least they put Kay into the conversation. What he does from there is really all on him. Sonic’s main course to victory here will be to rely on his speed as usual and just completely overwhelm Kay. So long as Sonic continues to go full blast there really shouldn’t be a problem here. Kay will really struggle to keep up for very long. Sonic wins.
