Smart Decision

A disaster that uses the wind just like Rudy was surrounding them from all sides.

Since it chose wind as it's attribute, it didn't have a physical body that they could target easily.

Xion chose to erase his presence entirely in order to not get attacked sneakily by the disaster.

As for Rudy, he had to do everything in his power to block the wind blades that kept coming from all directions.

"How annoying.."

Xion commented from nowhere. Rudy looked to the side, at the source of the sound but couldn't find anyone there.

'How is he masking his presence so perfectly?'

Rudy also knew how to do that. There were countless incidents during the battle where his enemy couldn't even tell he was onto them till the last moment.

He used the wind surrounding him to mask his presence, hide his scent, erase the sound of his footsteps and even distort his position at times.
