When another group of Avengers leaped into the battlefield, they drew everyone's attention. They looked almost exactly like the local Avengers, with only slight differences in their outfits. Their faces, expressions, and movements all seemed copied from the same mold.
The two Captain Americas linked up and both hurled their shields, their postures and stances identical, even the arcs of the shields' flight perfectly symmetrical. The Main Universe Black Widow reached out, grabbed the streetlight across from her, and swung over, while the other one, in perfect tacit cooperation, took advantage of his feint and struck an alien in the shoulder with a Widow's Sting.
The two Spider-Men were even more dizzying to watch. One swung in from this side, the other swept over from that side. One used webbing to interfere, the other came flying down with a midair kick. Hulk was not about to be outdone either. One swung a utility pole and smashed with it, while the other lifted a car and swatted outward. The two Hawkeyes seized high ground to the east and west; one used Explosive Arrows, the other Smoke Arrows, constantly providing anti-air fire support.
But if anyone looked the coolest, it was, of course, Iron Man. Besides the suits they were wearing, each of them had brought two extra sets of mecha. However, the local Iron Man's mecha had been sent to evacuate the crowd, so Main Universe Iron Man gave him one of his. The two had clearly shared control permissions long ago. The four Tin Cans on the field responded as naturally as their own arms and fingers, continuously bombarding the ground.
More S.H.I.E.L.D. agents rushed over as well, and of course the military's helicopters and Fighter Jets were not absent either. For a time, artillery fire raged across the streets
