I agree TonySansNom

From what I remember from this long post, an Exis awakened and he decompressed the earth to the size of a FREAKING marble, and that wasn't considered significant to be a top 5 Exis. Phantaminum is one of the 5 strongest in the entire TUS. So his awakening must have been on much greater scale. Here's some calculations

SUI said each floor is as big as the area of the US.

So...

USA area= 9.857 million km2

9.857 millionX137= 1,350,490,000

At least 1,350,490,000!!

Although it has a bigger surface area it would still have a smaller mass. And it's harder to decompress something with a larger mass. So it's impossible for him to have had his awakening in the tower.
