Another thing about this: This video shows that Legend, Alexandria and Eidolon were all early parahumans. Add Scion and the fact that Eidolon is still considered one of the strongest capes in the world, and it seems like there may have been a tendency for stronger capes early on.
If there was such a tendency and it’s not just a matter of me using statistically insignificant numbers to support this idea, there are a couple different reasons there could be for that.
Maybe the Dandelions need to spend an amount of a finite energy to bestow powers, and are running low after bestowing strong powers early?
Or maybe they have a regenerating energy they spend, and changed tactics at one point, going for many weaker parahumans rather than few strong ones?
Either of these theories may also explain why younger triggerers supposedly tend to get stronger powers. If I’m right that the Dandelions are equipping humanity to face the threat Dinah predicted, they might be reserving stronger powers for those who are more likely to live long enough to face this threat before dying of old age (if not killed by other things, that is).
