Midnight

Twilight is a mysterious army in Digimon Xros Wars.

SkullKnightmon
SkullKnightmon is an unscrupulous Digimon who serves as the brains behind Twilight.

When Shoutmon X4 and MetalGreymon appear to have DarkKnightmon on the ropes, he orders Nene to use Xros Open to split him back into SkullKnightmon and DeadlyAxemon, allowing him to attack each of them one-on-one. After regaining the advantage, he has Nene DigiXros him and DeadlyAxemon together to SkullKnightmon Big Axe Mode.

Attacks
 * Spear Needle
 * Breast-eye Wink

DeadlyAxemon
DeadlyAxemon is SkullKnightmon's sworn brother, an incredibly strong Digimon that can DigiXros with SkullKnightmon to create a multitude of powerful forms.

Attacks
 * Air Slicer: Runs between the opponents at the speed of light, who aren't even able to realize it before they're cut down.
 * Aqua Rage: Spews a powerful solution that dissolves everything.
 * Aqua Regia: Liquefies himself using Aqua Rage and swallows up all of his surroundings.

Damemon & Tyutyumon
Damemon was accidentally born when the drifting waste data of feces in the Digital World's dust randomly combined and mutated. His partner is Tyutyumon. 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, he has a bad habit of criticizing people without reading the atmosphere, regardless of the person or situation. Because he constantly says it while criticizing every little part of the imperial army, he is disliked by Tactimon and Blastmon.

Attacks
 * Bunbun Ken (ブンブン拳): A punch that almost always misses.
 * Gun Vulcan: Launches bad-smelling objects.
 * Boo~st Attack: Spreads smelly gasses as he strikes.

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.
