I see what you mean it would seem like the heroes could just get new powers to get out of a tough situation, but what about the characters we don't really see use their powers. Nico for example, we don't see him alot it either series, especially not his powers so for all we know he has developed Umbrakinesis other than shadow travel, or even fear inducing charmspeak (fearspeak?) to get people to do what he wants. It wouldn't really be developing a new power just kind of revealing a power he developed a while back that we haven't/couldn't have seen.
