Double is a tough Megaman fighter and definitely not someone you want to underestimate. He’s fairly fast and strong with a good amount of variety in his attacks. It just won’t be enough though. Aiolos is a whole lot faster and also has more combat experience. He won’t fall for any tricks that Double may try to pull off and he is durable enough where even if a trick would work, it wouldn’t deal any damage. Aiolos is incredibly durable and could take hits from Double for a long time and not feel a thing. Sagittarius Aiolos wins.
