Tony's eyes went wide, when he saw that the strength of these men was almost the same as his, maybe only a few distinguishes them.
After the Shield appeared in front of the man, he smiled looking at the four people he had to guard. As Rainbraz had said, he was the guardian of the four people in front of him now.
He showed his power to be able to make several shields, indeed the color of the shield and the shape he showed the four of them, very much resembled Tony's shield. However, there are some strengths that Hagalaz doesn't have, which is where Tony has those powers.
The man doesn't show the strength to run fast, he only shows his strength to be able to make shields and various weapons to attack, and his yellow clothes make him look like Tony's overpowering mode.
