Ability to be invisible, fly and capability to teleport.

Flying

I really like the idea of having wings because every time when I travel in a plane and watch the world below through a window, I used to admire how big this world it. Having wings can give me that opportunity to observe this world from any higher location. But if we go for wings them our current eyes may not be enough for vision, we will need hawk eyes to observe what's going on below when we are flying.

Invisibility

The ability to become invisible is a nice feature that anyone can have. If we have that feature, we will be able to do so many things. But it will not be interesting if the feature is available for everyone. It should be available only when we achieve something or do some enhancements. It should not be easily affordable. But there is a high possibility that invisibility can induce lots of negative things as well. It can increase theft and abuse.

Teleportation

This is an excellent capability one can have. This makes it easy to travel from one place to another without any necessity to actually travel. We should be able to disappear from any place and appear in a place that we want to be. This will be a great skill to have.
