Codon Stream

Description
The Codon Stream is the system of rivers of "Green lava" that spread throughout Primus. The stream originates in a volcano, which is actually the processing plant for the DNA of the stream. Originally, it contained the samples of all the living creatures in the Milky Way Galaxy, amounting to 1,000,899, however, Zs'Skayr added his own DNA by possessing the Florauna that provided the sample for Wildvine. Later on, Ben was able to aquire samples from Dr.Vicktor, the Thep Khufan, and the Loboan as they weren't cataloged in the Codon Stream because they resided in the Anur Belt system. In the movies "Race Against Time" and "Alien Swarm", Ben gained the forms of Eon and Nanomech (while the latter is said to appear in Ultimate Alien, the former hasn't been seen since his initally appearance). Recently, Ben obtained the sample of an alien from the Andromeda Galaxy called Bivalvan. Furthermore, it is hinted that Ben will also acquire the DNA of four more aliens from the Andromeda Galaxy, resulting a grand total of 1,000,909 samples.

Connection to the Omnitrix/Ultimatrix
The river has a special connection to the Omnitrix and now Ultimatrix, with the fact that the Omnitrix/Ultimatrix is actually a wireless receiver connected to the Codon Stream, allowing the Omnitrix/Ultimatrix to alter the current DNA of its user.

When activated, the Omnitrix/Ultimatrix opens up a holographic display of all aliens unlocked. When the faceplate is pushed back into place, it emits a signal that is picked up by the volcano on Primus, then sent throughout the Codon Stream, and back to the Omnitrix/Ultimatrix, with the selected alien's DNA attached. The DNA is then sent to the users current DNA, and modified to fit the aliens DNA, and turn the user into the selected alien. This could be why there's a green background every time Ben turns into an alien in Alien Force. In Primus, it can be shown that someone can absorb the energy of the Codon Stream to become more powerful. Vilgax demonstrates this when he falls into the Codon Stream and grows 100 ft. tall. But soon the effects wore off and Vilgax returned to his normal size. If Primus or the Condom Stream are destroyed the Omnitrix/ Ultimatrix will become utterly useless and literally neutralized.
