Midnight

Twilight is a mysterious army in Digimon Xros Wars.

DarkKnightmon
DarkKnightmon is a DigiXros of SkullKnightmon and DeadlyAxemon, who have exchanged cups of brotherhood. Although his skills, including the ability to use the "Twin Spear" he wields to thrust, slash, sweep, or throw as the situation calls for, are very advanced, he will use any means to achieve his goals, and sometimes he will even be willing to betray his own comrades. He is an opponent that you don't want to turn into an enemy, if you can help it. He is the brains behind Twilight, using Nene as a figurehead by offering to get her brother back while having her gather dark energy for him so he can complete the Darkness Loader.

He first appears before Xros Heart after having Nene gather the darkness in the Heaven Zone. He then personally fights off both Xros Heart and Blue Flare while attempting to draft Deckerdramon to Twilight, having Nene temporary to split him back into his components to overpower Shoutmon x4 and Metal Greymon with their teamwork and alternate Digi Xros states..

By then, DarkKnightmon succeeds in his plan to obtain the Darkness Loader, using it to take control of Kiriha before revealing the item as it gives him the power to perform DigiXros on his own. He immediately uses it to DigiXros with his minions into a "Super DarkKnightmon", attempting to use his power to destroy everyone in the Zone but able to stop by Taiki and Kihira. He later resurfaces, revealed to be Bagramon's younger brother and they Twilight was actually a branch of the Bagra Army.

Tsuwamon & Tyutyumon
Tsuwamon is a ninja Digimon with his partner Tyutyumon, sent by DarkKnightmon to spy the Bagra Army in the guise of Damemon. Lilithmon picked him up to be used as a clown for the empire's army, and he settled down in the Bagra Army's headquarters before anyone noticed. Since "No good, no good!" (ダメダメ！) is his favorite phrase as Damemon, he has a bad habit of criticizing people without reading the atmosphere, regardless of the person or situation.
