Apocalmon is    powerful since he can destroy whole dimension but millenniummon can do the same and survive,   plus milleniummon  can control time and travel between dimensions,  and has better feats than Apokalimom  In the future he defeated  the digidestined and conquered their universes also he created evil clones of them, actually in the game he destroyed some universes,  it is considered one of the most powerful digimon, and if it is killed he evolves to Moonmilleniumon that has the same powers but is also  is capable to destroy the opponent's  soul, he can create digimon and even he resurected the villains of the anime.

there are little  information about it, since brave tamer was only released in japan, but he  is considered one of the most powerful digimon,   in the game they used a plot device to defeat him, since he always wanted to be Ryo's partner, he doesn't want to kill Ryo, so he don't use is powers on him, in the end he fuses with monodramon to be ryo's partner and the future was  restored.

The one that appears in Digimon Xcross manga is just a clone of him, many times weaker it doesn't have the chains that  seal its true power.
