The ORCA, alternatively the Orca, is a device used to replicate the bioacoustics used by Titans, effectively communicating with them as well as controlling them to some extent by replicating the commands of Alphas.
After discovering that Titans communicate using the same calls, Mark Russell began to work on the ORCA with his wife Emma, before abandoning the project. Unbeknownst to him, Emma continued working on the ORCA, using a prototype on MUTO Prime, and took the untested but final design with her when she went to watch the birth of Titanus Mosura, or "Mothra". When Mothra became alarmed and enraged after the attempts to contain her failed, she began to attack the Monarch operatives, and Emma prevented Dr. Mancini from killing Mothra by attempting to subdue her with the ORCA. The ORCA managed to find Mothra’s frequency at the last second, convincing Mothra to stand down. Immediately afterwards, Alan Jonah attacked, seemingly capturing Emma, her daughter Madison, as well as the ORCA.
Emma later used the ORCA to wake Ghidorah, who broke free from the remains of the ice he was frozen in, the majority having been decimated by explosives. Madison took the ORCA in an attempt to prevent Ghidorah from killing Mark; although Emma took it back before Madison can use it, Emma herself then halted Ghidorah temporarily. Soon afterwards, the ORCA was used to awaken the Titan contained within the next targeted Monarch outpost - which contained Rodan. Although the ORCA was intended to wake the other dormant Titans as well, Ghidorah did this first.
Horrified at what Jonah and Emma were doing, Madison later stole the ORCA, attempting to use it in Boston to calm the Titans and prevent their attacks; however, Ghidorah remained unaffected due to being of a different origin to the other Titans and traced the ORCA to its source, and many other Titans - including Godzilla, Mothra, Rodan, Behemoth, Scylla, Methuselah, a MUTO, and several Leafwings - were summoned directly to Boston. Attempting to destroy the ORCA, Ghidorah was prevented from killing Madison by the arriving Godzilla, but after Godzilla fell, Emma lured Ghidorah away using the ORCA; as he killed her, Ghidorah also destroyed the ORCA.
