This is just me: I think standard attack (punch, kick) should do the 1 damage just like any street person or mook with unlimited punches available. But if you put points into attack, you have trained and invested so your listed attacks should do double your regular damage because you have trained and practiced to deliver those attacks. Your signature ability at 3rd level should deal your relevant STAT in damage or prevent that much in damage.

There's still the narrative element to take into account as well.

A fast character with a speed of 8 might only get +2 Defence but when it actually comes to telling the story they'd be able to outrace Superman, landing an attack and getting clear before he had a chance to counter... and then get shot at by heat vision beams which they can dodge, using one of their own special defences.

[@The Kid Lantern] Having said that, I'm not sure what the point of the special attack are when they're not going to do any extra damage than a standard melee attack would.

Perhaps make it that basic attacks always cause 1 damage, no matter what Strength you have. Special attacks could then cause an additional +1 damage if Strength is 1-5 and an additional +2 if Strength is higher than that.

The Parademon with 2 Speed should've gotten three attacks in the first post, but only attacked once?

Spitfire with Speed 5 should've had four attacks, but again only took one?
