If you've ever wanted to see Tony in a white-hot rage, Tales of Suspense #71 - the conclusion of the Titanium Man arc - is the issue you want to read. This is how Tony behaves when he thinks one of his best friends has died on his account.

But Happy isn't dead just yet, as we soon learn:

Jeez, the irony in this issue is absolutely torturous. This right here justifies the whole concept of Tony's secret identity. (Though I have nothing against the MCU for abandoning it.)

Like I said, by the time Tony finally finishes off the fight with the big, green commie, he's pissed. Make a note, readers: don't hurt Tony's friends, or he will eff you up!

Tony has no time for celebrations -- not while his friend is dying in the hospital! <3

Grah! My poor heart! Seriously, Tony: just tell her who you are. It's not like you'd be revealing your secret to the whole world. And quite frankly, you need a few close confidants who are fully informed of your extracurricular activities. After all, you're medically fragile (something your employees should know) -- and you've taken on a monstrous burden!
