Tony made something that can stand up to the beam from the Power Stone like I’m gaping at how much I love him.
Everyone else is out of commission and Tony is going up against Thanos alone and he made him bleed
Also it did remind me of that quote from Vanko which was something about once you make god bleed people stop believing in them and the sharks will come and I don’t know if that parallel was intentional for “all that for a drop of blood” but I wanted to point it out anyway
