"It's not a very good superhero name."

"It really isn't."

"Is there any way to put about a preferable one?"

"Typically the newspapers do the naming."

"You could write to the newspaper."

"I think they rather enjoy being the ones to do the naming... I could probably convince them to change it if I offered to be interviewed or something of that nature, I suppose?"

"Probably a bad idea given your secret identity."

"I could do so via writing, but it doesn't seem very important either way. It also seems possible it's an appealing name to commoners, even if it doesn't match my sensibilities."

"Does it matter - to anything besides newspaper sales - if your codename appeals to commoners?"

"Concievably I might benefit from it politically, but it's rather unlikely."

"How can you benefit from it politically if it's secret who you are?"

"People might be more likely to trust Ton O' Iron with information about empowered criminals."

"But they can't... contact you."

"The likely situation in which this happens is one where I show up to a crime in progress, the perpetrators escape, and the victims have useful information to tell me."

"I guess, sure."

"Probably not very important, even then."

"I mean, it could be, but not very predictably? But since you don't have a great way to change your name it doesn't matter."

"Quite."

Would Haru like to look through some more of the campaigns?

Sure, what've they got here.

A glowing orb of light that burned anything it touched and weakened the powers of those close to it.

A giant two-headed pig which spawned smaller duplicates the size of houses, which spawned their own duplicates the size of horses, which spawned further duplicates, all the way down to ant-sized creatures. Also, several of the empowered got sick after the battle.  

A living glass maze, including walls that appeared solid but instead led you to other portions of the maze, often used to redirect the attacks of empowered to hit other empowered. Additionally, a strange being made of bone haunted the maze. Or several such beings, it's unclear.

Maybe the ant-sized pigs spawned germ-sized pigs? Did they rule that out somehow or just assume that ants were the end of it?

Any kind of pattern to how the bits of the maze connected up with each other?

They did not rule that out.

Yes, though the campaigns don't explain what it was, just that someone figured out a way to determine which panes of glass were actually portals and where each would lead.

...do they always lead to fixed places? Are there ever new ones? Can they be directed?

Reading in-between the lines, it seems they always lead to the same places, there were new ones as the maze slowly grew (though that has since stopped), and they could not be directed.

So probably none of them lead to his universe but, like, are there any that don't definitely not lead to his universe.
