Exoatmosphere
My take on this stage is that you would fight on the blue platform of energy created by Platinum Robo. Essentially, the main platform would function like Final Destination, being completely flat with a ledge at either end. In the background, Jergingha (Planet Destruction Form) would be fighting Platinum Robo and the Wonder-eyes'd Gah-Goojins, and Jergingha would stop periodically to attack the stage.
Attack 1 - Jergingha crosses his arms and laughs, summoning a series of up to 5 cyber-walls, similar to the ones he summoned in the final battle in The Wonderful 101. These cyber-walls can either be oriented horizontally, causing them to function like soft platforms, or vertically, causing them to function like walls. After a minute or so, these cyber-walls fizzle out, returning the stage to its default, Final Destination-esque layout. This allows the stage to change dynamically for a short period of time. This attack is Jergingha's most common.
Attack 2 - Jergingha reveals his shoulder cannons, laughs, and fires a series of missiles upwards. A few seconds later, red reticles and laser pointers begin to appear on the stage, signaling where the missiles will land. Shortly after a given reticle appears, a missile will follow, exploding in blue flames when it hits either the ground or an opponent. These missiles inflict roughly 10% and moderate knockback, KO'ing at about 115%. This is Jergingha's second-most common attack.
Attack 3 - Jergingha laughs and holds up his arm behind the current leader. His fingertips start to glow bright red, and a targeting lasers emit from them, showing exactly where the laser beams will hit. Jergingha then moves his hand around slowly, following the leader, as his fingertips charge up power. Once the attack is fully charged, a distinctive sound effect plays, Jergingha stops moving his hand, and he yells as the lasers shoot out of his fingers. These lasers deal electric-type damage and trap opponents in a series of weak hits, inflicting roughly 30% if all hits connect. The final strike, however, is more powerful than the rest, inflicting strong knockback and KO'ing at 100%. This is Jergingha's least common attack.
Additionally, "Jergingha - Planet Destruction Form" and "ST01 Roll Out, Wonderful 100!" would be moved to this stage, and multiple new songs would be introduced. The complete song selection for Exoatmosphere would be...
