A portal is a pink mechanism used for traveling from Cybersite to another, though the ability can be extended to between Cyberspace and Earth. As such, this is the only way the Cybersquad can come into Cyberspace. Portals are controlled mainly by Motherboard, though there are other ways around it as well, as seen in A Fraction of a Chance, where portal dust was the source. If portal transportation process is interrupted, the portal travellers will get stuck in its dimension and slowly dematerialize. The only way to get the prisoner out is through the Universal Vortex Opener, as Digit demonstrated in saving Matt, Jackie, and Inez.
