Daiteioh is the combined form of Teioh, Kuuoh and Rikuoh after Momotaro activated the command Victory Combination. During the initation for the merger, the Gokuracruiser materializes the Rainbow Field into existence, therefore letting the three core units go inside it as they proceed to combine. Unlike the three core units, Daiteioh boosts performance on both air and land.
Usually, when needed, it can combine further with Dairyuoh to form into Perfect Daiteioh.
It's finishing move: "Kaiser Daidan End" involves the Daitei-Shield firing a laser of sorts to trap it's enemy as Daitei-Oh immediately proceeds to do a double slash to finish it's opponent off.
