Isolation Dome

The Isolation Dome is a dome that isolates a room its used from the rest of the world.

Overview
When activated, the switches pop up from the ground and power surges around the tips to close it inside a barrier. The dome also separates from the earth and floata around in space. It was first used by Leo Akaba to prevent Yuya Sakaki and Yuri from going inside ARC-V to become Zarc. Declan, Riley, Sora, and Aster were also trapped with them until Yuya became the Supreme King Dragon Zarc, causing the dome to explode and returning the room back to Duel Academy.
