He takes one down quick and the other will fall. He seems like the does what he has to do in order to get the job done. Taking down a whole ship with a dagger is beyond anything IM and War Machine have ever done considering they have better weapons.
Problem is both IM and WM can fly and Heimdall cannot. And though I consider him more powerful than either IM or WM, he's not so superior over them that he can take them down quickly.
Even Thor didn't take out IM quite that quick, and Thor is considered the best Asgardian warrior 2nd only to Odin.
True, however he was able to take down a space ship with a dagger, on the flip side Thor wasn't trying to kill Ironman I don't believe as earth is in his realm to protect and not kill its people, which is what he was trying to prevent Loki from doing in his speech to him, and we didn't get to see the whole fight as cap interfered with him, for the most part Ironman was holding his own had had the advantage most of the fight. I see Heimdal not being held back by these emotions.
We also didn't get to see his tri beam attack which I'm sure would have chopped Thor's in half. So I guess it could go either way if one thinks the Tri Beam could kill an Asgarudian such as Loki, Thor or Heimdal. Its hard to chose a clear winner. I guess I favor Heimdal cause I really respect him and his power.
I think the tri-beam would hurt an Asgardian but probably won't cut that deeply into them. That laser wasn't powerful enough to cut through the leviathan's hide. Hulk's punch crushed the leviathan. Thor tanked Hulk's punch.
I don't think that laser he was using was the Tri- Beam. As stated in IM2, it was a one off and was disposed of after use, and had its own power source as they fell off and detached after he used them.
Y'all are forgetting that Thor amped Iron Man by 500% for that fight, still held back and still was crushing his armor. It is fair to say that Thor could have one shotted Tony if he wanted to.
Doubt the IM duo could hurt Heimdall, he seems to be upper-tier Asgardian in line with Thor and Odin.
No idea how's he's going to hit either of them with his sword though, unless they act stupid and get into his range. Thrown dagger might be able to take one out.
