Thor was late, but Clint and the others were about to find out why and Terrax was in for a lesson in Asgardian-level dramatic entrances. The kind of thing that should have been depicted in the murals of a van in the 70s. It had taken a while to manipulate the Odinforce to pull off the idea Thor had - he could have just made it happen but he was cautious about how he used such power on Midgard, slow and steady may not win the race but it also didn't get your brains splattered against a wall. Ares and Brunhilde were on the ground and Thor knew that they could hold the line while he put his plan into motion - a plan that he didn't tell anybody else about beforehand. As previously stated, dramatic entrance.
The skies darkened and thunder heralded what was to come. The wind shifted and grew strong as lightning began to dance in the clouds in the northeast. For the briefest of moments after each flash of lightning a colossal figure larger than Surtur could be seen, eyes glowing blue before the figure vanished in the calamitous thunder that followed. Between the rumblings there was a void of silence as if the coming storm commanded all things to be silent, and all things yielded.
Above the Pyramid base black clouds started to rotate ominously and in the eerie silence before the roar of the thunder there came another sound - one that gods and celestial invaders would not know but one that humans could not mistake. Shrill sirens rising in pitch before falling into deeper more dire tones... tornado sirens.
The clouds came down in a great vortex to touch the earth, a monstrosity of a tornado that created a perimeter around the base to help contain the trespassers, it did not move, nor did it pose an immediate threat to the team gathered to keep Ronan's forces from overwhelming Midgard's defenses. Having established the perimeter Thor, King of Asgard descended upon the battlefield in a flash of lightning and with a sudden surge of electricity and debris from his landing popping into the air around him he swatted the charged rocks at Terrax using mighty Mjolnir in rapid succession like a pitching machine. Walking towards the Avengers gathered he brought his uru mallet down on a bug creature with a satisfying crunch before sending another spiraling into its fellows charged with lightning like a bomb. "My apologies for being late, as short handed as we are I was coming up with a way to keep these vile creatures contained. It will not last for very long so whatever plans thou mightest have, now would be the time. And Barton? Stay away from the wall. I will not be held responsible for you winding up in Kansas or worse...New Jersey."
