Iron Man vs Zauriel
The Iron Avenger vs The Angel from Heaven's Eagle Host. No prep. Standard Iron Man armor. Zauriel has his flaming sword and armor. For those who don't know:
Armor
Zauriel has three major pieces of equipment. The first is his set of armor. Although built of Earthly materials, this prototype is designed by the engineers of Heaven and is blessed with magical properties that are theoretically impossible to replicate on Earth. This suit of armor greatly enhances Zauriel's physical properties, including strength, durability, foot speed, agility, flight speed and stamina. Because of the Heavenly properties of the armor, it can be assumed that no other being could don it, let alone make use of its abilities.
Flaming Sword
Zauriel's second piece of equipment is his flaming sword. This sword, which is characteristic of both guardian angels depicted thus far, is directly bonded to Zauriel's will, which logically prevents anyone else from using it. Because it is controlled by Zauriel's will, the sword can cut literally anything, including otherwise intangible objects and people, and even dimensional fabric itself. Magically pumped up by teammates, Zauriel was once able to cut a hole in the dimensional barrier separating Heaven and Earth, enabling himself and his team to transverse dimensions. The fiery sword is also able to emit blasts of fire.
