So kirby absorbed superman.

Having no chance of escaping a situation and things in my lungs that shouldn't be there.

Drowning is the worst of both.

Definitely daredevil.

That said, there is only one correct answer to this:

@petey_is_spidey:

go on desmos graphing calculator (https://www.desmos.com/calculator) and copy and paste this into it:

v=\sqrt{\frac{\frac{\left(\left(E+mc^2\right)^2-m^2c^4\right)}{m^2c^2}}{1+\frac{\left(\left(E+mc^2\right)^2-m^2c^4\right)}{m^2c^4}}}

set a c slider to the speed of light, and a m slider to any mass you want (it doesn't work for light sadly, . The v value (y axis, sorry about that, but I figured having v isolated in an equation would be useful) is the velocity, and E (the x axis) is how much energy it would take to reach that velocity.

If you want to include the energy in the mass of the object, all you have to do is use this instead:

v=\sqrt{\frac{\frac{\left(\left(E\right)^2-m^2c^4\right)}{m^2c^2}}{1+\frac{\left(\left(E\right)^2-m^2c^4\right)}{m^2c^4}}}

if you've taken calculus, you should be able to figure out why v can't equal c. Either way, I'm going to make another equation for the other way around (energy isolated, plug in v) to make things easier for other people.

Edit: E=\sqrt{\left(mc^2\right)^2+\left(\frac{\left(mvc\right)}{\sqrt{1-\frac{v^2}{c^2}}}\right)^2}-mc^2 for energy without taking intrinsic mass into account

E=\sqrt{\left(mc^2\right)^2+\left(\frac{\left(mvc\right)}{\sqrt{1-\frac{v^2}{c^2}}}\right)^2} for energy taking it into account

@petey_is_spidey: Ok, so you know how asymptotes and limits work than.

The amount of energy needed to go the speed of light goes to infinity as velocity reaches the speed of light.

That means there is literally NO value you can throw at it that would give you light speed.

@petey_is_spidey: Just curious, what is your math background? Algebra, geometry, trig, precalc, calc, multivariable calc, linear algebra, ext.

I think that it'd be lot more effective to figure out how much energy each character can control, and because they can fly, calculate out the amount of propulsion they can create. Combat speed would be a lot more difficult, but we can work that out later.

Unlimited energy? In that case, all of this is pointless. Literally all of this comes down to "everyone is equally immortal and all powerful". And even than, going by the math, if you make the energy a function of velocity, the limit as velocity approaches c certainly does approach infinity, but even than that also means that infinite energy can only cause you to approach infinity. Infinite energy STILL doesn't get you to light speed.

Furthermore, due to time dilation, you'd age yourself into oblivion. So, are all of these characters also immortal? If so, they would still spend (in their psyche) an eternity in social isolation, and go insane.

And finally, gravity doesn't work by mass, it works by energy. Having infinite energy, especially focused into a point the size of a human, you would have a black hole of infinite size created.

We are simply a natural consequence of the world having the laws of physics it does. We have just as much (or little, depending on how you look at it) meaning as a rock, hurricane, galaxy, or supernova.
