Wot? No galumphing?
Hate to say it, but think about what anime characters do...
...ok and action movies...
So, leaping physically impossible distance, arrow-cutting, outrunning explosions, parkour to the nth degree, superhuman stealth to & beyond the point of invisibility or of "teleporting" away in the instant someone takes their eyes off you, escape-artistry to the point of functional insubstantiality (literally nothing can hold you), "irresistible" persuasion or intimidation (hitting WILL to impose conditions). You might also consider utilities that specifically work in skill challenges: An Epic Daily based on streetwise, nature or dungeoneering to unerringly find a creature, place or thing in the corresponding environment, giving enough automatic successes to compete a Complexity 1 Challenge (or one less, so a check is still required); a similar mechanic could be used for Bluff/Diplomacy/Insight in social challenges, each for somewhat different goals thereof (or within a more complex challenge).
Throwing Allies impossibly far. Sensing an attack from impossibly far. Those persuasions/diplomacy affecting even enemies of course.
Definitely some skill challenge functions. I am thinking using any Martial Practice converted into an action instead of a process.
