BlackWarGreymon is the Mega-Level form of Pagumon. He is WarDukDrialmon's closest friend in the Warriors' Circle, but was second to WereGarurumon while he was alive. Of all of the members of the Warriors' Circle, BlackWarGreymon causes the most trouble for Sally and Drialmon. Not to mention trouble for the Real World entirely.
BlackWarGreymon is very similar to WarGreymon in stature and size but the differences are BlackWarGreymon doesn't have the crest of courage on the back of his Black Chrome Digizoid Armor.
Unlike with BlackWarGreymon's previous stages, he achieved Mega before CanuDukDrialmon had. This occurred when the Digimon who had been friends with the one who'd killed WereGarurumon came after CanuDukDrialmon. The two comrades found they could not defeat this powerful Mega Digimon. When it made to perform the finishing blow on CanuDukDrialmon, MetalGreymon was filled with such purpose; he flew to CanuDukDrialmon's aid.
The purpose that had filled MetalGreymon was so strong, it triggered his digivolution to BlackWarGreymon. Covering CanuDukDrialmon with his own body, BlackWarGreymon deflected the Mega's blow with only his "Brave Shield". With its blow blocked, and defenses down, BlackWarGreymon spun around and cleaved the Mega Digimon apart with his "Dramon Killers".
Thus, BlackWarGreymon saved CanuDukDrialmon, who digivolved to WarDukDrialmon sometime later.
Digital Years Later
Rumor had begun to spread throughout the Digital World, of a mysterious power in the Real World that gave Digimon the power to digivolve. Word of this power had reached the Circle, so the highest ranked members of the Warriors' Circle gathered for a council: WarDukDrialmon, Ifritdramon, BlackWarGreymon, MasterTyrannomon, and VictoryGreymon. While VictoryGreymon and Ifritdramon agreed that the power would be beneficial for the group. MasterTyrannomon and BlackWarGreymon agreed to disagree with them, however, stating that the group didn't need to "cheat", and that digivolving at one's own pace proved their strength.
Wishing to avoid dissension, WarDukDrialmon announced he would go alone to the Digital World and investigate this power himself. His plan was to see if this "power" was what rumor set it up as, and if it would be beneficial or not to the Circle.
This caused mixed feelings in the Circle, but especially in BlackWarGreymon. Since WarDukDrialmon was adamant in going solo on this mission, it set BlackWarGreymon on edge, despite the many assurances WarDukDrialmon gave.
- Terra Destroyer (Gaia Force): Creates a massive sphere of energy and throws it.
- Dramon Destroyer (Dramon Killer): A thrust with his claws.
- Black Tornado: He begins to spin and becomes a tornado, then rushes into his enemy.
It is unknown where Zurumon was and what he did during his time as a Fresh Digimon. From Pagumon to BlackWarGreymon, he has never spoken of this part of his life.
Pagumon is BlackWarGreymon's In-Training form.
Even as an In-Training, Pagumon was always self-confident and looking for a fight. Due to this, plus his usually dauntless nature, he got into a lot of fights. Despite not always coming out as the victor, since most, if not all, of the opponents he challenged were higher levels than he, Pagumon continually challenged others.
One day, Pagumon was feeling especially tough, and for the first time, challenged a Champion Digimon. The Digimon was a Centarumon, and after being taunted and all-round antagonized by Pagumon, eventually retaliated against the In-Training. Pagumon was initially satisfied to have succeeded in provoking Centaurumon. But Centaurumon's attacks grew increasingly merciless as it was more and more angered by Pagumon.
Finally, Pagumon's evasion faltered, and Centaurumon's Solar Ray made contact. The vast difference in level between the two Digimon only worsened the damage it caused Pagumon. Injured and too weak to fight, Pagumon tried to surrender and prevent further pain. But Centaurumon was far too angry, and made to destroy Pagumon and absorb his Data. Fearful for his life, Pagumon ran away and hid in a tiny hole caused by some rocks. Centaurumon followed, and tried to destroy the hole around Pagumon.
But, as fate would have it, Drialmon was passing by at this time, and spotted Centaurumon attempting to destroy an inferior Digimon. Appalled by the lack of honor displayed by Centaurumon, Drialmon attacked. Despite being Rookie against Champion, Drialmon easily defeated Centaurumon, nonchalantly absorbing the Champion's Data as he approached Pagumon's hiding spot.
Pagumon was surprised to find a Rookie had defeated Centaurumon. After all, if Pagumon the In-Training couldn't defeat Centaurumon, definitely no Digimon could...right? Drialmon offered to help Pagumon to become stronger, and Pagumon grudgingly accepted, initially peeved to have to be saved.
But as the Digi-Years passed, Drialmon and Pagumon grew close, and they only grew closer as they Digivolved together. This meeting would always be considered the Unofficial Founding of the Warriors' Circle.
BlackAgumon is BlackWarGreymon's Rookie form.
When Pagumon finally digivolved to his Rookie, BlackAgumon, the first thing he did was challenge Drialmon. Though at first he didn't succeed in victory, just the fact he could hold his own against Drialmon satisfied him. But, only partially, as BlackAgumon made to challenge Drialmon on a regular basis, never ceasing till his first victory against his comrade. Once it finally came, their bond only grew stronger, as fellow Warriors.
The challenges were as looked forward to by Drialmon as they were by BlackAgumon. Even after BlackAgumon got his first win against Drialmon, they continued these spars, the excuse being they needed to keep themselves at top form. While true, it was also for the fun of it, with the added bonus of keeping them sane.
BlackGreymon is BlackWarGreymon's Champion form.
BlackAgumon had achieved Champion sometime after Drialmon had. While it annoyed the now BlackGreymon, he'd have his "vengeance" via their spars. Since finding and befriending WereGarurumon, BlackGreymon had been a tad jealous of the friendship between DukGrowlmon and WereGarurumon. But he refused to let his jealousy ruin his friendship with DukGrowlmon.
Despite his initial jealousy, BlackGreymon soon came to enjoy WereGarurumon's company, and consider him a part of the Group.
Like with his Champion Stage, digivolving to Ultimate occurred for MetalGreymon after DukGrowlmon. But due to the nature of DukGrowlmon's digivolution to CanuDukDrialmon, MetalGreymon did not care one bit he came after CanuDukDrialmon once again. MetalGreymon also helped CanuDukDrialmon by NOT letting him win in their spars. If anything, MetalGreymon fought harder, making sure CanuDukDrialmon didn't fall to his sense of loss.
It was around this time a Flarerizamon had joined them, and also contributed to helping CanuDukDrialmon.
The story of BlackWarGreymon's digivolution to this stage is presently a mystery...for it has yet to happen.
