The VR Hub System is most likely based on the Time Twister used by Crash and Coco in Crash Bandicoot: Warped. However, the Hub System cannot travel through time, only through space. Like the time twister, the VR Hub System has five areas with six warp portals. It also has a load/save screen and can receive holographic transmissions similar to the warp rooms from Cortex Strikes Back.
Between the events of Crash Bandicoot: Warped and before the start of The Wrath of Cortex, Coco had been working on developing the VR Hub System underneath the bandicoot house. After Uka Uka releases the Elementals, Aku Aku asks if she's finished work on the VR Hub System as it would most likely be needed in order to stop the Elementals. Coco makes her final adjustments and the system is ready to go.
Crash and Coco enter the VR Hub System and use it to find crystals to defeat the Elementals and Cortex's new super weapon, Crunch Bandicoot. Most of the events of The Wrath of Cortex take place in the VR Hub System.
