Rahu II is the upgraded form of Rahu I. The statistics of this model are greater then that of all the stats found on the Rahu I set, showing more defensive and aerial/ground mobility and it is the fastest out of all the Rahu sets. The Rahu II set is slightly different then the Rahu I set as both the body, pod and gun are now upgraded. It is seen in Custom Robo (GameCube) as an autonomous robo. It appears to be some form of transitional stage between Rahu I and Rahu III, with pieces of it's anatomy much bulkier than others. This may be caused by prematurely releasing Rahu when it was being forced to evolve during Oboro's experiments to dive in it.
