Obtaining Ghidorah's head proved that Taylor's plan in this plane was already half complete. The other half was to secure ORCA.
Perhaps to outsiders, ORCA was merely a device used to attract and lightly manipulate Titans, but in Taylor's eyes, the knowledge of sound waves contained within ORCA would be useful for his future.
ORCA was essentially a composite sonic wave, influencing Titans through invisible sound waves that integrated simulations of all kinds of animal and human sounds.
From a wizard's perspective, a technological creation like ORCA being able to influence the subjective will of a Level 2 Creature meant that the sonic synthesis, sound simulation, and sound frequencies involved were immensely valuable knowledge.
Furthermore, Taylor had designated this plane as a bloodline repository and a gathering place for Titans. In the future, ORCA could also help him draw those powerful Titans together.
In short, ORCA was extremely important to Taylor. He knew that ORCA would be completely destroyed during Godzilla's battle against Ghidorah, and judging by the attitudes of Monarch's second leader, Mark, toward both Titans and ORCA—
After ORCA was destroyed, Mark would most likely never recreate the device that had caused his ex-wife's death and triggered the Titans' rampage.
Therefore, Taylor intended to take ORCA for himself. If possible, it would be even better to obtain a more detailed understanding of ORCA's principles from Mark.
Across the endless planes, sound waves were practically fundamental elements of those worlds. Many planes also contained hulking creatures similar to Titans. If he could use ORCA's principles to create a personal ORCA of his own—
Even if it could only mildly affect those giant beasts, such as driving them away and making them restless, or attracting them and making them enraged, then his personal version of ORCA would undoubtedly be an
