History
At some point prior to the movie, Emma contacted Alan Jonah and his ecoterrorist group and offered to give them the ORCA her husband had designed so they could use it to awaken the other Titans. After Jonah and his men killed the other members of Emma's MONARCH expedition, they retrieved Emma and her daughter Madison along with the ORCA.

Russell then traveled with them to Antarctica where they intended to use the ORCA to awaken "Monster Zero". However, while they were there they were attacked by MONARCH forces and Emma found herself faced by her ex-husband, Mark Russell. Mark attempted to convince Madison to come over to him but before he could do so Emma activated the detonator and set off the explosives around the area Monster Zero was contained in, releasing King Ghidorah. Emma and the rest of Alan Jonah's forces then made their escape on helicopter as Ghidorah rampaged and attacked the MONARCH forces.

However, when they got back to Alan Jonah's base, they discovered that King Ghidorah was already awakening the other Titans and commanding them to wipe out the humans and terraform the world to his will. Though Jonah was fine with this, Emma began to have doubts. Emma later discovered that her daughter Madison had stolen the ORCA and was heading to New York City to transmit a signal to disrupt Ghidorah's communication with the other Titans and get them to stop attacking.

Emma then went to New York City herself to rescue her daughter. While there Emma ended up sacrificing herself to use to ORCA to lure away King Ghidorah and give Godzilla time to recover, resulting in Ghidorah killing her.
