The only reason DRDA can at once be the same strong as STARS is the same reason, the desire to revenge, not only to STARS, but also to the Justice army and other Evil army. In other words , they turned against the whole world.

But they never afraid of it, because all the members have already died for one time(That's the origin of the name Digimon Revenge Death Army), and come back from the hell after the contact with devil, later known as the only remain member of FFP(Future Fate Philosopher). They, the death never be afraid, until the appearance of STARS.

If STARS is considered only a extreme example, the birth of the UNIVERSE, threw away the theory automatically.

Quoting a sentence from the fifth general of the UNIVERSE, Fuwu Qian "If an army has these following characters: extremely united, extremely hate for simple thing, extremely high-technique, and extremely tactful, then if will never fail. And UNIVERSE, grabbed all of them."

UNIVERSE, one of the three most powerful organizations in the real world, was mysterious, for anyone, from its first appearance to the final fall. Its members, dolphins, were the most ancient beast according to those organisms who still exist in the 20th century. Although human beings studied even utilized dolphins for dozens of years, finally they found all the data about dolphins were totally wrong. When dolphins removed their superficial mask and turned from angels to devils in only a moment and started the "Chaos War", human beings lost two third of the land in only a few weeks as they never met this kind of army before. Thanks to Human Being's greed.

HB, the weakest force according to the STARS and UNIVERSE, didn't seemed have any sign of collapsing. According to the theory of the Universal Society, UNIVERSE belonged to Suppresser, and HB belonged to revolter.

Human beings have the surprising speed of development which cannot be compared with UNIVERSE. Under the protection of STARS, it took HB only a few months to create an army strong enough to fight with UNIVERSE. When most of them lost their family and home town, nothing except desire of revenge stimulate them to continue living in this world and asked UNIVERSE for payment. A famous sentence said by the previous five-star general Douglas MacArthur was quoted by HB again and again: "I am out, but I will be back again."

Two worlds, three civilizations, four organizations, used their tears and blood, prove Universal Society purposed by Pico Devimon Victor Harry perfectly.

Although STARS finally fail, for Arman, the nightmare didn't over.

And now, they were back.
