As the title suggests, I’d choose healing powers but combined with an extra attribute like telepathy or superstrength.

Clearly healing is essential in a world of illness, injury, and crime; I would love to use my regenerative abilities to be helpful in that sense and ease some of the burden on medic teams overwhelmed by patients. But on top of that, mixing in the superstrength or one other attribute like telepathy or mind control would really seal the deal in my mind.

If you’ve played any RPG, you may succumb to the stereotype that the healer class is not very skilled or useful at times. Soooo to combat this, it would be great in-game and in real life to have a really capable, strong, and strategic healer with offensive capabilities or manipulation in prep for worst case scenario. And this superstrength or telepathy combo would be great for actually changing the world in one moment at a time and being perceptive about doing so. Thinking of ATLA’s Katara off the top of my head (btw bloodbending is wild), a perfect example of being versatile and combining skillsets! Or even TF2 honestly, lol. I’d also be thrilled to rep the healer class in a new lens to break norms and implications of weakness associated with taking care of oneself/others. In a less direct way, that would be changing the world as well. : )
