Question on Activation Powers
So, this is my first character in M&M 3e, I have not played before (about 6 years of D&D DM experience, so I have some TTRPG background) I have a speedster built primarily on the Quickstart Generator in the handbook that I would like to make dependent on a speed drug for his abilities. I currently have 3 different powers (Rapid Metabolism, Speedster Stunts with Rapid Attack and Sonic Boom, and Hard Target) and I would like to make all of them rely on a single activation. It doesn't make sense for him to take 3 different drugs to activate 3 different powers when they're all just ways of using his superspeed. I would like to add the Activation flaw on his Rapid metabolism ability, and I'm wondering if there's any way to add a flaw to the other two powers that make them dependent on the first being active. None of the flaws I'm seeing seem to do that, but I was wondering if there's one that will do the job that I'm not understanding. Thank you!
