Although in one Silver Age story, Superman grew long hair, a beard, and long fingernails because of exposure to that useful plot device, Red Kryptonite. He was able to get himself barbereed by haviong Supergirl and Krypto simultaneously use their heat vision on him.
This proves two things:
1.) In the Silver Age, Superman and other Kryptonians were totally invulnerable, except when it was inconvenient (otherwise General Kang could’ve used his fingernails on Superman, or the Kandor folk could’ve descended on Superman en mass and torched him)
2.) Superman trusted his dog an awful lot more than I’d trust my cats. (“Here, Midnight – hold the razor HERE. Now stroke gently. GENTLY!”)
She-Hulk can’t get drunk while she’s in her Hulky form.
However, if she drinks as She-Hulk and then changes back into Jen Walters, she’ll feel all the effects of the alcohol she dranks with the usual side-effects (vomit, etc.).
That’d be useful on a night out, I suppose. Drink all you want in your civilian identity and then when it’s time to drive home: poof! change into a seven-foot-tall atomic monster and you’re good to go.
Thank you, tangentially, for causing me to occupy an entire 30 minutes of should-be-working time reading the (surprisingly long) Wikipedia article on She-Hulk, mostly because I wanted to check my recollection that she didn’t change forms and was stuck in Big Greeny mode.
I was apparently wrong, but in my defense, I haven’t read comics on a regular basis since the late 80s. And I had no idea that she was actually married to J. Jonah Jameson’s kid…
But surely unprotected sex would be something to avoid anyway, as it’d probably be even more hazardous in the Marvel universe as it is in ours. Along with all the ordinary terrestrial STDs floating around, there’d no doubt also be freaky mutant viruses, gamma-irradiated pubic lice, Skrull herpes, etc.
Plus, of course, the risk that your partner might suddenly suck the life out of you.
Well, Krypto had human-level intelligence so long as he had super-powers, and clearly he and Superman (and presumably Supergirl) could communicate as if in English. So that’s reasonable (or as close to reasonable as you’ll get in a comic-book universe).
Not an issue for her, really. I think the only guy who really got pre-Crisis Kara Z’s motor running was her cousin, who could have dealt with the hymen pretty easily.
