I've recently discovered the awesomeness that is
I Love the Yeti. As the name implies, the site offers tons of artwork of the Yeti, links to the Yeti art of others, and a look at things which might seem Yeti at first glance, but on closer inspection, aren't.
I was perusing my comic book collection for the first time in years (honest) and was surprised at how many times a Yeti showed up on covers.
As a tip of the cap to I Love the Yeti, here are a few of them.
After the success early on of the Indiana Jones movies, Marvel Comics had a fairly decent series based on the the character. Naturally, he eventually ended up in the Himalayas.

I occasionally checked out the comic book Alpha Flight. Mainly because they crossed paths with the X-Men on a frequent basis. Alpha Flight was kinda the Canadian version of the X-Men. They did have a member named Sasquatch, and yes, that's what he was. At one point, a shapeshifter decided the best way to fight Sasquatch, was to become one. The shapeshifter could only transform into white creatures so this is what you get...

Maybe we can classify that one in the not Yeti column?
Another that hovers on the Yeti/Not line comes from Batman.

In this issue, Batman is on the trail of a crook that leaves his victims frozen solid, kinda like Mr. Freeze. His investigation leads him to follow a champion skier as his prime suspect. His investigation leads him to discover the suspect's mother's diary. Here it's revealed that she was once stranded on a mountain and near death. She was rescued by a stranger who nursed her back to health. Apparently, she was very grateful. Not until after showing her gratitude did she realize who her hero really was..

Yeah. Him.
Now, I'm no expert, but even if they were waiting out a horrible snowstorm in a dark cave with no fire, wouldn't there be other ways of figuring out she was shacking up with a Yeti? Never mind.
Anyway, the son turned out to be a sort of superpowered combination of human and Yeti, able to change his looks from normal to, well, this:

What name is that? Snowman. Not really all that frightening, actually. Eh. Whatta ya gunna do? All the good cold-weather villain names were probably taken.
