The theme of the Dimensionals seems to be that they share a warped set of physics somehow, especially Thirnova. Gravitas has immense gravity, Thirnova is practically built on impossibilities, and Gigagush appears like a small galaxy, with a possible object of immense mass in the middle causing a nebulaic swirl around it. They serve as the top grouping for the middle groupings of Star Trip's Multi mode. The mission of this grouping is "Launch 50 burnt Meteos or more!" Successfully completing this mission will let the player choose to go to the Clean Air Club if the mission is completed successfully, or the player may choose to go to (or is forced to if the mission is failed) the Hot & Chillies.
