The codon stream
The codon stream a lava on primus that contains DNA of 1000019 lifeforms.
What part does the omnitrix have in all this? Well you see that it's a wireless connection device. That is connected to primus volcano the home of the codon stream.
When the omnitrix is pressed it sends a coded message to primus. The message will be interpreted as some sort of DNA the DNA will be took from a matrix witch will be sent to the Omnimatrixes matrix and grouped as DNA then will be put into the omnitrix matrix witch will be determined, calibrated, and multiplied creating a new matrix determined from the bigger one and will alter bens DNA to that of the matrix all in about 140.9 million nanoseconds 0.1409 seconds.
