Phlebotinum Rebel: He is the first unit to utilize the Angle of Light, a weapon that could counter enemy firepower. And he goes rogue at the end of the game. Unfortunately, the Enforcers already managed to replicate his ability, as seen in MESH.
Greed: Opens warpholes outside Metaspace to drag rich people in, kill them, and take their money. It also runs the corrupted city for the Defiance. In-game, it steals your money- as if being made of money wasn't enough.
Bloody Murder: Sends out heart-shaped blood cells that try to "molest" the player.
Combat Tentacles: May double as tentacles for naughty purposes, given that it represents the sin of Lust.
Eye Beams: Which look like a male's reproductive organ...
Freud Was Right: It looks like a heart crossed with a woman's reproductive organ. One of its attack patterns looks like a Gag Penis with two "circles", another of its attack patterns looks like a pair of Gag Boobs.
Two of the enemies it spawns are blood-cell like Mooks (that look like egg cells), and Wormicides (that resemble sperm).
Get Back Here Boss: Appears as the miniboss, then runs away after you beat its four large tentacles. In the Boss battle against it, it will try to run away after its health gets low.
Unstoppable Rage: This thing is rampaging through your home city, devastating it with destructive force and warheads. The only thing in its programing are rage and mindless destruction. Represents the sin of Wrath.
Stage 6: Spite
Always Accurate Attack: If you get caught in his angle, he will fire out his dark bullets, which will home in on you and kill you if you do not counter them in time. Thankfully, the dark bullets can be countered.
Redemption Equals Death: After his defeat, he gets impaled by Xero-Fin's Vigil Lance. Given that Vigil Lances are based off the Holy Lance of Longinus, he doesn't survive for long. But he manages to tell you Xero-Fin's true intentions before dying.
Rush Boss: He has the lowest amount of health of all the bosses, but his attacks can drain away your lives pretty quickly. Plus, he teleports away if there are about 6 or so Holy Bullets on screen, making your holy bullets miss!
Teleport Spam: If you counter too many of his bullets at one go, he teleports away, making all of them miss. Grr.
