There was a very disturbing Hellraiser story where one of Constantine’s ancestors, under a spell of immortality, was buried alive. John eventually dig him up and killed him—300+ years later.
Black Bolt can’t sing.
Well, he CAN. It would be a mighty expensive aria, though.
But a tattoo is essentially colored scar tissue. Healing factors seem to preclude those a bit.
I may be wrong.
He could become lead singer for Hitchhiker’s Guide to the Galaxy’s Disaster Area.
What about the sperm? Wouldn’t she kill them before they had a chance to reach there destination?
BTW what happens if rouge touches a plant or a animal?
It turns red.
I believe you are - a tattoo consists of ink molecules of a specific size that makes them too big to be “processed out” by the body, so they remain just beneath the skin - and show through because skin is very translucent.
Which doesn’t sound like scarring.
I am assuming that just like a Healing Factor can overcome big, normally fatal wounds, it could process much bigger ink molecules than your average person’s healing system…
Actually, being able to see someone and read their emotional state would be an advantage in learning to read body language. (Admittedly, it would reduce the need for the latter, but you’d probably pick it up anyway just from noticing that such-and-such an expression tends to go with such-and-such a thought.)
Add to that the likelihood that Xavier would have put some thought and study into it, both out of intellectual property and as a contingency plan in the event he ever temporarily lost his powers.
(Of course, like Batman’s contingency plans, Professor X’s typically go horribly awry, but this is the exception.)
but isn’t this the one place where you are expected to be? lol. 
Curse you, now I’ve got this scenario in my head:
Cannonball: “I heard that Rogue sucked the life out of Gambit.”
Sunspot: “Dude, she does that? My girlfriend won’t even do it with the lights on!”
Dr. Manhattan can’t - or feels that he can’t - do anything to prevent disasters, even when he foresees them.
The Martian Manhunter can’t walk through a public place unnoticed.
Mr. Incredible apparently can’t slam a car door shut without damaging the car. 
Unless he turns invisible 
Or shape-shifts into a normal-looking person.
Maybe I’m being wooshed.
Um…he can both change his shape AND turn invisible. Of course he can. Well, Batman can often see through his disguises, and Superman, if he puts his mind to it (and knows JJ is there in the first place) can find him when he’s invisible–but apart from those two, John is quite stealthy when he feels like it.

Jus’ another few…
•I think I’ve read/seen of a few Vampires who can no longer pallate solid food.
•Many cyborgs and most androids can’t have children.
On a related note, IIRC, the Teen Titans’ Cyborg gained great strength upon his cyborging operation, but it took a long time before he was able to pick up an egg without breaking it. Other characters (superpowered biologicals like The Thing, or early/discount model prosthetic body users from Ghost in the Shell) have had similar problems with delicate objects or things that require fine dexterity.
*As far as I know, he’s the first mechanical movie monster to actually progress past “silently carry fainted, broken-ankled damsel around in his mighty arms before being gunned down” to a full “sex offender.” (It was the 70s, and he didn’t have arms.)
Yeah, for a woman who spends a lot of time in mutant angst over it she sure does overlook a lot of simple, obvious solutions to her problem. Personally I think she can control her powers; it’s just a cry for attention.
There’s plenty of cases where healing factors push bullets out of a body, for example. I’m with you, I think tattoos probably wouldn’t work.
Not only that, but haven’t we seen mutant restraining collars? Y’know, things that temporarily cancel out mutant powers? Unless they give you cancer, or have a 1/12 chance of making your eyeballs explode out your ass or something, it seems like it’d be handy to have one of those lying around the bedroom.
The invisible man can’t get drunk and streak through campus. Well he could, but it wouldn’t make much difference.
Have you seen “The Son of The Invisible Man” segment from Amazon Women on the Moon (starring Ed Begley Jr.)? If not, grab it and watch it. Hilarious.
