Cant's opinion on shapeshifting; why it's the best superpower

I think I said a couple things here before, but I wanna say that stuff in a page dedicated entirely to it.

Have you ever wanted to fly? Have you ever wanted superstrength or superspeed? Have you ever wanted to prank a friend? All of that could come in one superpower: shapeshifting. Shapeshifting is a superpower that gives you incomprehensible abilities.

First off, if you want flight, you could turn into a bird. If that's too slow for you, you could turn into an airplane assuming your friend is a pilot.

Secondly, if you want superstrength, you could turn into a lion or bear, they both are really strong and have great fighting abilities in terms of close range. With superspeed, you could turn into light.

Finally, for joke uses as pranking, just turn into a horse in a place where horses wouldn't normally be.

What's stopping you from turning into the sun?
