In Monarch: Legacy of Monsters, a gamma radiation simulator is a device that can be used to call MUTOs.
In 1955, Bill, Keiko, and Lee are sent isotopic signatures similar to the ones from the Philippines that led them to the USS Lawton.
Bill and Keiko go to Japan to investigate these isotopic signatures and meet Dr. Suzuki on Hateruma Island. Dr. Suzuki greets them and welcomes them to what he calls Monster Island.
Dr. Suzuki is seen using a big ball-shaped device that he calls a gamma radiation simulator.
The device’s function
Dr. Suzuki’s data suggests that whatever is out here on this island generates gamma radiation at cosmic levels, and that’s why he constructed a gamma radiation simulator.
Using the device, Dr. Suzuki stimulates gamma radiation signals, and in return, whatever is out there generates radiation.
In simpler terms, Keiko describes the device as Titan phone, whereas Bill calls it Titan bait. Dr. Suzuki prefers Titan phone.
The device’s function shares similarities with Orca, a device created by Mark and Emma Rusell to communicate with titans.
The results
The device is sent on a boat into the water. It’s not like it immediately attracts a titan. Hence, the group is required to give the device some time.
When Bill complains about it, Dr. Suzuki points out why catching fish is called fishing, and not catching. The same applies to attracting a titan using Dr. Suzuki’s device.
Eventually, someone or something throws the device back onto the surface. It’s Godzilla who shows up, confirming that Dr. Suzuki’s invention works and that he didn’t die from the nuclear attack on him in 1954 at Bikini Atoll.
In 2015, Hiroshi is seen using a similar device, which leads to Godzilla appearing again in the Algerian Desert.
