Can I do this:
Mach One has a power potential of three, so his flight is at 3 (meaning he can fly at 150 km/h).
Using freebies, can I pay 6 points to increase his power potential to six, and then an additional 15 points to increase his flight to 6?
I also want to give Mach One a 5 to Brawl, but only when he's flying. Instead of paying 2 freebie points for 1 skill point, can I pay 1 freebie point to make Mach One's Brawl look like (Brawl: 2/5* *only in flight)
