What four letter word do a garment, animals, mold and crests have in common?

I'm getting so big now you should see me I'm beautiful. But you'll never see me, at least not if I lead to your funeral! I'm also akin to a video game, where stage four whoops your ass again and again!

Take away my last letter, I'm the first person you met. Leave me whole, and I'm where dirty shoes are set. Add a T, and a common man's name appears. Add an E, and I'll be your friend for years. What am I?

To the person who stole my place in line, I’m now . . .

What do you get when you cross a snowman with a vampire?
