SPEED: Speed is crucial in-battle, mostly to avoid, or slam into opponents at mach speeds.
If we take a look at Delta here, we see that he has nothing to fly with, but he has a trick up his sleeve.
If wanted, he can create a blaster on its back, and shoot away at high speed, aften even reaching 817 m/ph, fasten then hawks kick their prey out of the skies. If he boosted away, and slammed into Iron knight, i´d had so much force that it has the power to shatter an entire rib cage. luckily Iron knight has armour, and can also have high speeds when using his trhusters. These can go up to at least 789 mp/h, so it would not take a sweat for him to reel an ferrari in. But, its suit has this core that needs to charge overwhile, like tony stark. If he´d go in overdrive, its core would tire out and end the battle immedeatly.
So, with this downside, SPEED goes to Delta.
