Sepsis is a mutant pathogen, and the main antagonist of KoopaGalaxain's main comic series, Periodic Genesis: Dawn of Sepsis.
Appearance[]
In his base form, nicknamed the Lord of Disease, Sepsis resembles Godzilla, but with red countershading and numerous red horns and spines. In his Ultimate Phenomenon (UP), Sepsis is radically different in appearance, becoming a titanic creature comprised of pulsating flesh with numerous black pearl-like tumours interspersed within. The largest of these tumours is Sepsis's brain. In this form, Sepsis gains two heads that sit atop long necks covered in writhing veins. Sepsis also has a large spike erupting out of his back in this form.
History[]
Periodic Genesis: Dawn of Sepsis[]
Interim Saga[]
Sepsis was originally a failed creation of WeegeeZilla, who never developed beyond a single cell. While being prepared for storage, Sepsis grew rapidly, devastating the city before leaving. After taking on his first form, Sepsis then created three subordinates from his cellular material, each based around disease; Keratos, Myos and Organon. He then issued them his commands: to kill all life on Planet Earth, starting with the PGKs!
Sepsis later briefly appeared as an afterimage after Organon killed Luster Caesium, where he spoke cryptically of his plans to Linkzilla, one of WeegeeZilla's more distant allies, but vanished when the swordsman tried to attack him.
Keratos Saga[]
Off-screen, Keratos met with Myos to inform him that Keratos had failed in his mission and was close to death. He then had Myos assure him that he would be able to face any resistance to his plans. Sepsis then met with Organon, who did much the same.
Council of Creators[]
Sepsis first emerged in the destroyed village of Lake on the Isle of Wight in the twentieth episode, where he reprimanded his subordinate Keratos for his failures in killing Koopa and the other creators, and, having brought Keratos back to life, sent him to fight the Creators again, although Myos, Sepsis' second subordinate, chose to defy orders and went ahead of Keratos to fight the Creators himself.
Sepsis is currently set to make a major appearance at some point after Keratos and Organon are defeated.
Abilities[]

Sepsis's base form, and his 'default' form that he takes. While Sepsis seems to be at his weakest here, he is still incredibly powerful, and thus should not be taken lightly.
Abilities[]
- Toxin Fangs (毒素の牙 Dokuso no Kiba?): Sepsis can inject opponents with numerous deadly poisons and bacterial toxins through his hollow teeth.
- Lysis Ray (溶解熱線 Yōkai Nessen?): Sepsis can fire a bright red energy beam from his mouth, similar in colour to Keratos's Scalpel Beam, but many orders of magnitude stronger than it. This beam inflicts a dissolving effect on the areas of opponents and nearby objects that it hits, 'melting' away anything it comes into contact with if given enough time.
- Defensive Afterimage (守備の残像 Shubi no Zanzō?): Sepsis can generate after-images of himself. Each of these afterimages can move independently and land a single duplicated version of whatever attack Sepsis is using on an opponent before dissipating. The duplicated move is only slightly weaker than if Sepsis were to do so himself.
- Wicked Eye Beams (邪眼ビーム Jagan Bīmu?): Sepsis can fire energetic red beams from his eyes, capable of setting objects on fire and blasting flesh from opponents.
- Transformation (変身 Henshin?): When required, Sepsis can regenerate all damage and change form into Sepsis Type U. In times of duress, Sepsis may also change directly from his Lord of Disease form to his Ultimate Phenomenon, bypassing his Type U form altogether.

Sepsis's Ultra-esque form. This particular form of Sepsis is his most agile form, and as such is particularly efficient at using dramatic physical moves and ranged beam weaponry alike.
Abilities[]
- Bacterium Beam (細菌ビーム バクテリウムビーム? Bakuteriumu Bīmu): Sepsis Type U's greatest technique, and the one he will resort to the most if given the chance. The Bacterium Beam is fired from Sepsis' left arm, and is performed in a similar way to Ultraman's Specium Ray. In addition to causing destruction, the Bacterium Beam can also cause affected opponents to suffer from a similar effect to Sepsis' Toxin Bite, as Sepsis is unable to do the latter in this form.
- Ability Duplicator (能力複製機 Nōryoku Fukusei-ki?): Sepsis Type U is able to duplicate techniques, abilities or weapons used by his three goons, Keratos, Myos and Organon.
- Keratos Blade (ケラトスブレイド Keratosu Burēdo?): A copied version of Keratos' bladed weapons. Sepsis Type U can grow the weapons on his hands and then use them to fight opponents with.
- Twin Jaw Beam (ツインジョー光線 Tsuinjō Kōsen?): A copied version of Myos's signature beam, fired from Sepsis Type U's right hand. Sepsis Type U's version of this beam begins as a single beam, but splits into two to strike opponents more than once, or multiple opponents at a time.

Sepsis's titanic final form, and his true form. This form is Sepsis's strongest, and he uses its fearsome abilities to full effect to strike fear and terror into those who oppose him.
Abilities[]
- Neo Bacterium Beam (ネオバクテリウムビーム Neo Bakuteriumu Bīmu?): An upgraded form of Sepsis Type-U's Bacterium Beam, Sepsis can fire a concentrated beam of energy from his mouths. Though it no longer inflicts toxins on those it affects, its destructive power is drastically increased.
- Neo Lysis Ray (ネオ溶解熱線 Neo Yōkai Nessen?): An upgraded form of Sepsis (Lord of Disease)'s Lysis Ray, fired from Sepsis's mouths. This beam is considerably stronger than Sepsis's standard Lysis Ray, and induces rapid cellular necrosis when used against living targets, causing tissue to die and decay away at a dramatically-heightened rate.
- Vulnific Eviscerators (バルニフィック エヴィセレーター Barunifikku Evu~iserētā?): Sepsis sports two elongated tendrils that extend from each side of his body. These tendrils have grasping claws at each tip, capable of inflicting an incredible grip and allowing Sepsis to rip into opponents or dismember them.
- Cellular Reconfiguration (細胞の再構成 Saibō no sai Kōsei?): In his Ultimate Phenomenon form, Sepsis can spontaneously modify his genome to increase the strength of his attacks or adapt against the attacks of his opponents.
Trivia[]
- Originally, Sepsis was going to look very different. In this 'Pathogen Concept' (pictured in one of the infobox tabbers), Sepsis was going to be a 'decaying' Godzilla-esque monster who had destroyed eyes, a malformed set of undulating tail 'fins', black dorsal spines, and a huge blade on his tail. Sepsis also had no additional forms. This version of Sepsis was partially recycled into Organon's first design, before that sprite was lost with the destruction of my old laptop's first hard drive in August 2016. The sprite seen here is based directly on notes I'd written down about the concept at the time when I was thinking of ideas for Sepsis' design. Unfortunately, I didn't write anything down about exactly what role this early version of Sepsis would have, if at all, so that's a total mystery.
- Just as Caesium bears a resemblance to BurningGodzillaLord's Gamma, Sepsis bears a resemblance to another one of his NGKs, Epsilon. Epsilon and Sepsis have almost the same colour scheme, with the exception that Sepsis's skin is a slightly lighter shade of black.
- Sepsis's Ultimate Phenomenon form is one of a group of monsters that appeared on the Fan Made Kaiju Wikia's header graphic, along with Oh Pi, Servopent, P-rex and Venodragon.
- Sepsis' Ultimate Phenomenon form took over two months to complete.
