I wonder, what could answer that one without G.A.s understandable input of giving wrong impressions for injecting or taking something. I mean, of course a energy pack (or however you want to call your batteries

) can work but only for tech-oriented heroes.
True...I've seen stims in other games and didn't think much of it, but I suppose it does give the wrong impression. The beauty of the "inspiration" system as Golden Ace pointed out was that it came directly from the inner strength of the character. Like he said, they were "inspired" to do better and so they found the endurance, strength, etc. to keep going. So maybe we should think more abstractly and come up with options more internal than food, stims, etc. rather than external influences...
What internally motivates/allows people to keep going in stressful situations? I've been brainstorming so I'll throw some ideas out there:
-Focus
-Willpower - could call them "Wills"
-Clarity
-Notions
-Elevations
-Fervor
-Ardency - Ardencies?
-Vibrance - Vibrancies?
-Impulses
-Force - though I'm sure Disney/Lucas Arts will have a word or two about that...
-Resolves
-Essences
-Sparks
And my favorite so far:
Coruscation:
1. a sudden gleam or flash of light.
2. a striking display of brilliance or wit.
Could be simplified down to "
Cores." Also sounds techy enough to apply to tech heroes.
