Suggested by Destroyer Gemini Spark is quite quick and strong. He is easily one of the strongest Megaman Star Force characters out there. That being said, DBZ has always been in a league of its own when it comes to power levels. I don’t think Cooler would bat an eye at Spark’s abilities. A single energy blast would be enough to end the fight and with Cooler’s abilities it is basically guaranteed that he will land this hit. He won’t even need his final form. Cooler wins.
