Soundwave, the Decepticon communications officer and one of Megatron's staunchest supporters, doesn't just master the frequencies that carry information across Earth, he revels in them. Stationed high in the upper atmosphere and capable of processing millions of data streams at once, he is fully capable of taking over communications on a planetary scale. Whether he uses this to direct civilization or destroy it remains to be seen.
During the 1970s, Soundwave tried to hide the Ark's presence on the moon by gaining human contacts in the United States and Soviet Union, whose creative accounting would render further trips to the moon financially unfeasible. One of these was Dylan Gould's father, while Dylan himself would later accept Soundwave as a "client."In 2009, in orbit in Earth's upper atmosphere, Soundwave received a transmission from Wheelie, who was following Mikaela Banes, and instructed him to obtain a surviving shard of the AllSpark in her possession. He found a satellite transmitting a conversation between NEST and the United States military. Latching onto and hacking into it to listen, Soundwave overheard Theodore Galloway mention another shard of the AllSpark in storage at Diego Garcia, and of Megatron's burial in the Laurentian Abyss.
Formulating a plan, Soundwave waited until it would be nightfall on Diego Garcia, then ejected Ravage (who was equipped with Scalpel and the microcons comprising Reedman) to Diego Garcia to steal the shard. Once they had stolen the shard, they reunited with a quadrio of Constructicons and managed to resurrect their leader.
Soundwave remained in space, tapping into the satellite he had found. When Megatron decided to reveal the Transformers' presence on Earth after killing Optimus Prime, Soundwave issued the mobilization order to the waiting troops on the Nemesis. As the Decepticons streaked toward Earth, Soundwave tracked down Ron and Judy Witwicky in Paris. He called Judy on her cellphone, demanding to know where Sam was, which Judy dismissed as a crank call by a pervert. This allowed the Decepticons to track them down and capture them to use as bait for Sam.
When the CIA discovered that Sam was in Egypt, Soundwave relayed the information to the Decepticons. During Operation: Firestorm, Soundwave blocked the satellites covering the Egyptian area, making things appear normal. General Morshower was unconvinced though and got other local informants to know what was happening at the pyramids.
With the failure of Megatron and The Fallen's schemes, Soundwave and the Decepticons now planned to alert Optimus Prime to the Ark's presence on the moon so he could revive Sentinel Prime with the Matrix of Leadership for them.Soundwave went undercover on Earth as a Mercedes-Benz SLS AMG. He and his winged minion Laserbeak visited the incapicitated Megatron in Africa, and informed the ex-tyrant that Optimus had discovered an Ark fuel cell at the Chernobyl Nuclear Power Plant, and had recovered the body of Sentinel Prime and five of his Space Bridge Pillars. Megatron decided it was time to eliminate loose ends in their plan, so Soundwave sent Laserbeak to further draw out the Autobots by killing many of their human contacts, including Jerry Wang.
Meanwhile, the disguised Soundwave was "given" by their human ally Dylan Gould, the one human they did not kill, as a gift to Sam Witwicky's new girlfriend Carly Spencer. He was used as a car to transport Carly to Dylan's party. During the party, Sam and Carly tried to leave, only for Soundwave and Laserbeak to reveal themselves, and the sonic warrior took Carly hostage. Gould explained his relationship with the two Decepticons while Soundwave sadistically used his tentacles to mentally torture Carly, and the pair forced Sam into finding out the Autobot's plan for a counter-attack.During the Decepticon occupation of Chicago, Soundwave took several Autobots prisoner until Gould stated that things had gotten personal and the Autobots needed a lesson of respect, and Soundwave happily concurred: "No prisoners, only trophies". He and Barricade began by executing Que. He then selected Bumblebee to be his victim and dragged him forward, pushing him onto the body of his fallen comrade. He then told the Autobot to turn around as was about to execute him, when he was distracted by Wheelie and Brains' sabotage of a Decepticon aircraft carrier, raining fighters onto the battlefield. Bumblebee took advantage of this small slip of opportunity and punched Soundwave as they battled through the chaos, causing him to drop one of his guns. Evading Soundwave's sonic cannon blasts, Bumblebee eventually blasted part of Soundwave's leg, causing him to drop his remaining gun, and he lunged at the Autobot. Bumblebee then delivered the final blow by throwing an uppercut to Soundwave's torso and shooting Soundwave upwards, disintegrating his head, and casually flipping his body over to the side.
