How do INTJ actually act in real life?

Because when I search things about INTJ all I see is some badass mysterious anime villains, and it's not really realistic.. idk if I'm just extremely mistyped but I have never seen someone who acts like the stereotypical INTJ character in movies and shows.

Like am I an INTJ? Yes. Do I had moments when im extremely emotional with my friends? Also Yes

Are INTJ supposed to act like some cold genius professionals or..?

I have never in my life seen an INTJ who acts like that and I'm an INTJ

Pls tell me if I'm extremely mistyped or people just over exaggerat the shit out of INTJ

(Sorry for my english)
