Portal gunner is a tower. Obviously, is a reference to portal. It shoots 2 portals: 1 orange and 1 blue. If a bloon floats over a blue portal, it will come out of the orange one. Note that the orange portal will always be BEHIND a blue portal, and a bloon can only fly over the portal ONCE. NOTE: this was SirBardocks conception, but he let me adopt it, becouse he did not want it anymore.
