"...we could just evacuate the Earth?"

"But then people would keep getting powers no matter where we put them—probably—so that'd just move the problem elsewhere."

"Are aliens getting powers?"

"We don't know any aliens, but even if they're not that could just be because whatever makes powers hasn't reached them yet, they're probably many light-centuries away."

"Yeah, but we could put you light-centuries away if necessary. Some forms of magic are dimension-wide but some are tied to a planet. We might be able to figure it out with enough research."

"I guess... If it's tied to a planet would that mean I don't have access to my powers anymore? 'Cause... I kinda like 'em."

"Yeah, I bet. If you want we could go over to the Andromeda galaxy somewhere and you could check if they still work?"

"Okay. You have the coolest powers I'm kinda jealous."

"Demons are the best, aren't they? As soon as I heard about them I wanted to be one so badly - I actually went and lived in Hell for a while pretending - once we find my multiverse you can get more magic, too, they're careful on the ones you could destroy the world with but a track record of being responsible with superpowers helps there."

"Ooh, a track record, I have that!" He beams. "But okay, Andromeda, beam me up, Scotty!"

Here they are. In space somewhere, it'd take him longer to find a planet. He makes an Andalite Dome ship around them for the artificial gravity. "Okay! What do you need to test if your powers are still working?"

"Well—uh, actually, I'd need my workshop and to try to build something, I had a project I was procrastinating on..."

An exact copy of Hero's workshop is now right here on this Andalite dome ship.

Blink. Grin. Computer! Tap tap. Tap tap tap. Taptaptaptaptaptaptaptaptaptaptaptaptaptap...

Epic might recognise the glazed look on Hero's face, even though only half of it is visible. He seems to be really engrossed in whatever it is he's doing.

He knows that feeling. He flops on the grass and starts reading his books about parahumans.

The first one is very 101: it explains about Scion's first appearance (naked golden dude showed up floating in the middle of the ocean, literally no explanation has been found for this), and about the first heroes and the first villains (some of them were the people who first saw Scion), how Scion started heroing around the world (which kinda just happened out of the blue, but at least he stopped being naked for it), the birth of the Protectorate and the PRT—apparently Hero is the leader of the Protectorate, the displayed relationship between himself and Legend notwithstanding.

Relationships and stuff are confusing, powers and categories of powers are less confusing so he sticks with that.

Categories! Mover is powers related to enhanced mobility, Shaker is powers that change the environment, Brute is powers related to personal strength and/or resilience, Breaker is powers that alter the user's "state" during combat (like turning into mist, for example), Master is powers that can control other creatures, Tinker is powers related to being able to create advanced technology, Blaster is long-range offensive abilities, Thinker is any enhancement to senses or cognition, Striker is short-range not necessarily offensive powers, Changer is shapeshifting, Trump is any powers that interact directly with other powers, and finally Stranger relates to stealth and infiltration powers.

In addition to those types, powers are also usually given numbers to indicate rough level of ability. They were invented to classify villains, a few years back, but the public started using them on heroes, too, and they've started to stick.

He spends a while trying to work out what he'd be categorized as and then what sorts of hard limits on powers there seem to be.

Most powers are classified more based on how they're used in combat and how to react to them than anything intrinsic about them, although there are of course some regularities. His teleporting power would give him a "Mover Fuckton" classification—there are no numbers designed to describe something that can literally jump universes. Invisibility would likely be classified as a Breaker/Stranger power, and the application of demon magic to give him wings would be Changer. He could be classified as a Brute due to his indestructibility and depending on how he used the matter generation in combat, too, but it's fuzzier. The healing and turning-into-a-bird powers would be Striker, possibly Master, possibly Trump depending on whether people continued to have their powers in bird form. His regular senses alone would make him a Thinker, but osanwë's just overkill. His knowledge of future technology could reasonably make him a Tinker, and some more creative uses of matter generation could give him a rating in all other categories with the probable exception of Master.

As for hard limits, there aren't any known ones, but there's something called the 'Manton Effect' which is the observation that many powers seem to either work on living things, or work on nonliving things, with very little overlap.

That's interesting. He adds 'check if powers work on birded people' to the list of things to experiment with in the morning and resolves not to share any mind-altering magic songs.

After a few minutes Hero stops and looks at Epic. "Uh. Oops," he says, sounding sheepish. "Guess it works."

"Good. You might still have an adjacency limit, most things do, but we don't have a good way to check that. ...there's a magic song that speeds up your perceptions and thinking, it stacks on itself until you think about three and a half times as fast as normal but at that speed you get this annoying hangover when you come out of it and most people just use the one that doubles it. If you want to work faster."

"Okay wow yes I want that very much!!!!"

A snazzy 23rd century music player with all his non-mind-controlly songs is now on Hero's desk.
