Easy.

The ability to make and manipulate portals. You can travel anywhere nearly instantly. My version of this power assumes you can make the exit portal without physically seeing it. So you could make one at home, one at your work and never deal with traffic. Want to go to London for the weekend? Done.

The cool thing is that you could also bring things to you. Craving a soda? Pop one portal under the coke in your fridge and the other just above your hand. Boom! Gravity pulls the coke through the portal and drops it into your hand. So now you can summon items to you as well.

My version also includes manipulation of your portals. You placed them but can move them while they are active. This allows you to effectively “scan” things. Need to dig a trench? Keep one portal stationary and just pull the other through the dirt. Whatever you scan gets immediately teleported elsewhere.

If we are assuming a world in which superheroes are a thing, you become an absolute badass. Not God like. But you can’t be arrested because you’ll just leave. You can easily make “rods from God” a reality. You could “scan” a spear fast enough that it’s like shooting it from a cannon and impale your enemies. You can use your portals as perfect shields. All attacks would just be directed elsewhere.

I think about this power a lot. To be honest, It’s based on Gilgamesh’s powers from the Fate anime.
