"To open a wireframe portal in the third dimension, do." ~Neil DeGrasse Tyson
As shown above, there are three general types of wireframe portals. These three are known as cylindrical adventures, spherical travels and office cubicle. These are level one portals, meaning they do not require heavy knowledge of the science theory. However, the highest level of portals (level two) can be in nearly any shape. The Mutcuf One is capable of spawning these types of portals, as shown on the right. After a time (if nothing else enters the portal) the portal will degrade, turning orange-brown before disappearing completely. While degrading, objects can still enter the portal, which is a severe flaw and can completely ruin the thing on the other side if an enemy were to enter.
Portals allow ships to cross massive distances in a matter of nanoseconds. The exits can be hidden, and will only show up when then ship is ready to come out of the portal. A portal-capable ship is also able to deploy portals nearly everywhere when needed. If armed with portal-capable weapons (like the Maua's peanuts), then the user has a great advantage over their opponent.
The only known disadvantage of using a wireframe portal is that in order to transport, the object going in must be shredded apart and recombined after exiting the portal. This can sometimes cause trouble since the object (mainly ships) will not be ready for whatever is on the other side and may be destroyed by ships camping near the exit.
