The Battle of Puente Antiguo was an open confrontation that pitted S.H.I.E.L.D., Thor, Sif, and the Warriors Three against the Destroyer.
With Thor was exiled to Earth and Odin fell into the Odinsleep, the only eligible temporary replacement as king was Loki.
Loki was a destructive king whose only plans were to get the love of Odin and to kill Thor.
The Warriors Three and Lady Sif, unhappy with Loki's rule, attempted to discover a way to end Thor's exile, convincing Heimdall, gatekeeper of the Bifrost Bridge and the means of travelling between worlds, to allow them passage to Earth.
After their arrival, the four Asgardians were watched by S.H.I.E.L.D. agents Cale and Garrett.
Thor rejoiced to see them before they informed him that Odin was alive and that Loki was king. They saw another wormhole in the distance and realised that Loki had sent the Destroyer after them.
Thor, Jane Foster, Erik Selvig and Darcy Lewis began to evacuate Puente Antiguo as the Warriors Three and Sif formulated a plan to stop the Destroyer.
