Scylla

Scylla was awakened from her slumber in Arizona by King Ghidorah's call, which also awakened many other Titans around the world. Scylla's legs tore through the desert near an oilfield as she erupted from underground. Like the other Titans, Scylla rampaged through populated areas, destroying buildings in nearby Phoenix with her colossal legs. Eventually, she made her way to Boston along with Methuselah, Behemoth, the Queen MUTO, and a flock of Leafwings. There, they found the alpha they were following, Ghidorah, slain at the hands of Godzilla. Rodan approached Godzilla to challenge him, but was intimidated by his gaze and ultimately submitted. The other Titans all followed suit, each "bowing" in their own way to the new King of the Monsters. Later on, Scylla was reported to have left human civilization and taken up residence in a lake. The creature was also credited with slowing down the melting of the polar ice caps.
