Damage Values:
Since everything deals 1 damage to Duo (barring full Buster charges), the most important thing in this fight is keeping Duo in i-frames - in whatever way is possible. For a slightly optimized fight, you can try a “cf-0”-esque strat. The easiest way to do this is to mitigate charge time by hitting Duo with a Flash Bomb and letting that keep him in i-frames, then hit him with the charge when the Flash Bomb runs out.
*\* cf-0 refers to the intro boss in Mega Man X 2, where a lemon is fired from far away to allow iframes to dissipate, and the player uses that time to charge the buster*
