According to the early 2000s documentary series The Invisible Man, if you gain invisibility through the use of a Quicksilver gland, the Quicksilver shifts the light so some of it will penetrate to your retinas.
Either your eyes are pouring out dangerous levels of radiation at the thing you are looking at, or another source of x-ray is bombarding something for you to see the reflections.
I like this answer because, like... a lot of the others are "clever" misinterpretations of how powers classically work, trying to force real-life physics into superhero logic and stuff.
But no. Not this one. Your mind-reading powers can function exactly like how comic books say it should, and you can still be scarred by what you found rummaging through that one guy's head.
You're already fast enough to kill yourself by running into something or breaking a bone by punching something. Unless you had super durability you're just gonna kill yourself.
Hell even the friction between your feet and the ground would be like jamming your feet into a grinder.
Edit: This also applies for super strength. Without super durability the first time you used that strength it would rip all the muscles off your skeleton if not snap the bones outright.
As you say most special powers require other powers, like speedforce (in this case). Imagine laser vision that burns off your eyelids. Or thinking "Whoohoo I can fly!" and then as soon as you land you jam your femurs up through your chest cavity because your hip bones aren't up to touchdown.
Assume the air stops too, because why wouldn't it, then you might be frozen in place by the solid air. But even if you can apply a small force and move it around, getting it to go into your lungs consistently could be a real problem. Best case you could keep walking forward with an open mouth, leaving vacuum surrounded by extra dense air behind you. That would make for some real excitement when time resumes. And even in that case it would become increasingly hard to stay in the same area and gather enough air to breathe. The highly variable density as you take it in might cause problems too - depends on how/where it starts being affected by time as you take it in.
Light too, if nothing is moving relative to you, then nothing is expending energy to make light, so you'd be probably suffocating, and in total darkness, even outside (at best after 8 minutes and 20 seconds: If the light isn't stopped entirely then I assume the speed of light being constant would hold. Otherwise if it's not stopped and not at full C then it would be so heavily redshifted that seeing would not be feasible anyway.) And if light does keep moving while time is stopped, then when time resumes, the sun (and planets, etc) would blink out for a while, visible to everyone presumably.
I think it's in one of the sequals to John dies at the end, with the spiders where this happens after he takes the sauce and stops time. The grass doesn't bend under his feet so it's like running on blades and then he gets shot. Nope, just turns out he ran into a butterfly. Even when he gets to where he's going he's powerless to change anything s everything is frozen.
Super-speed. Even just being the Flash and living faster than everyone else around you would be torture. It's bad enough just being a normal human fast walker and having to walk behind all these goddamn slow walkers. Then add in the potential to get into accidents easier or even killing innocent bystanders by running through them (as in The Boyz), I'm just not sure super-speed would be worth it, unless it were more like a "time-freezing" ability where you can turn it on and off at will and just walk around doing whatever while everyone else is essentially frozen in place or at a highly reduced speed. Maybe that's even what the Flash's ability actually is, I don't follow the comic at all.
I feel like the "actually the earth is moving so you'd end up in space" complaints about teleportation/time-travel rely on some heavy assumptions about how those things would work (eg. What the teleportation power uses as a rest reference frame)
Happens already. As a taller guy, I get asked to reach stuff all the time. As a bigger guy, I get asked to carry stuff or pick up things that people think are heavy. This is just more of the same
Off topic but related: you guys just broke the whole super hero concept for me. Now I can't go back to reading comics or watching movies ignoring all of these things. I suppose I am happy to be my normal me (though perhaps super strength isn't so bad)!
