Conscientious Deafness
This super power allows me to become completely serene by tuning out all superfluous discussion. The only drawback is it only works if everyone else around is already getting along pretty well.
My father was a terrible villain who could make anything happen just by thinking about it. Ironically that meant everyone was always upset around me, leading me to almost never learn how to use my inherited form of the super power.
My brother did not even get much of a super power at all except talking very very very extremely serenely for a while (when he was not being an a%^$) which is how I finally learned. If he can learn to use his power for many hours at a time and there is enough feedback between our powers some suggest a legend from our family's past.
In that case in our combined powers presence angry 'latent-zombies' may learn to relax. This will let them resist fraternizing with other actual zombies. Then our family name, ruined by our father, can be redeemed by slowing a future zombie plague.
The name 'Zomborer' is given to any persons that can stop a zombie plague with their deafness superpower. (A Supreme Zomborer that can amplify their own deafness has not been known for ages.)
So a great deal depends upon the cultivation of conscientious amplified deafness. That is the way 'deaf listening' transfers by osmosis for short therapeutic moments to latent-zombies.
Has our father's awful legacy already slowed our progress too much? Is the zombie plague already upon us? Only time will tell, in babbling ways, that hopefully I may never have to listen to.
A retreat to isolate suspected latent-zombies is being set up as we speak by local officials. But I'm not listening to that beaurocratic noise either.
Tagline for the movie: the bottom of the barrel makes a sound but can you not here it well enough to prevent others
