An unfortunate oversight in the 2013/01/27 update was that these "dynamic" target robots had incredibly predictable attack patterns - that is to say, each target robot only had one ability! I've since updated the game to scale target abilities along with the level scaling it already does. As you beat each mission in a phase, the target robots gain another semi-random ability. First they gain an Energy Boost ability, then a random Attack/Defense/Speed Boost, then a random Attack/Defense/Speed Break, and then finaly a Attack/Defense/Speed Mode (with the order shifted slightly for Wily mode). Because these abilities are randomized each time you fight the target, each battle has the potential to play out quite differently. I've also tweaked all the robot AI to use Energy Boost a little less often - it was becoming a hassle and that's no fun so why not fix it?
