The power of the Swarm Body Ego completely fused with Lancelot's weak and smaller soul. Its powers so strong that it completely overwhelmed it. The fusion was painful, as it made Lancelot's very soul struggle to keep itself from shattering into pieces.
Maria had not completely fused with him because of this, as Lancelot had a smaller soul compared to most of her other Undead, mostly because he was fairly new into the group, and unlike Kuro, Darkbound, or Mercury, whose souls were composed of hundreds of smaller souls, he was just a single soul.
However, it wasn't as if Maria couldn't do it. She quickly brought upon dozens of souls that were floating around, the souls of the very Ice Giants they defeated, as she raised them as Undead while merging a dozen other souls into Lancelot's own soul, strengthening it. A+ Rank beings' souls were surely strong.
The Swarm Body Soul fused into his body, strengthening it much more. His appearance finally beginning to change as Lancelot's arms, legs, and torso grew three times their original size. His black and purple exoskeleton changed color to a dark green and black color, with several sharp spikes growing over his body.
His abdomen turned into a long scorpion-like stinger with a sharp spear-like end. And his wings turned larger and stronger, like those of beetles. His six arms grew sharp claws, and his face turned slightly more humanoid, although his bug-like eyes remained, slightly more narrowed while his mandibles seemed sharper.
Argus noticed Lancelot's transformation, as he smiled at the challenge presented to him. He quickly rushed towards the insect, imbuing more Mana and Divine Power into his Axe and muscles, enhancing his physical strength greatly.
"Come at me, insect!" Laughed Argus, swinging his axe down like a giant guillotine about to slash through Lancelot's body.
However, Lancelot this time managed to intercept the attack, moving Sleipnir at an incredible speed and using the divine spear to pierce through Argus' hands and arms, leaving countless wounds!
CLASH! CLASH! CLASH! CLASH!
Although Argus had overwhelming strength, he couldn't be as fast as Lancelot, not in a million years. Argus gritted his teeth as he continued attacking with all his might, unleashing icicle spears everywhere and blizzards, but Lancelot evaded them or unleashed his own swarms to stop them.
"Unnggh…! W-What the…?!" Argus felt surprised. Lancelot had suddenly turned into a completely different being now. He furiously unleashed the power of the Ice Giants, axe attacks, kicks, ice magic, and punches started raining down upon Lancelot like giant meteors.
CLASH! CLASH! CLASH! CLASH! CLASH!
Lancelot roared furiously, unleashing countless blows back. He barely had 50 seconds before his transformation were to end, he was going all out, even as his entire body was being torn apart and regenerated constantly.
"GRAAAAGGH! You damn INSECT! H-How come you're this strong?! UUAAGGH…!"
Argus fell into the floor, his gigantic body making the ground around him shake furiously. His Divine Power had been almost exhausted as he unleashed so many attacks he could had destroyed an entire mountain by himself… yet Lancelot evaded or intercept them, even as his arms and legs were torn apart, he merely grew new ones.
Lancelot fell down from the skies, his spear about to pierce Argus' chest! The Ice Giant Hero grew desperate as the ring in one of his hands suddenly began glowing brightly, a special Divine Artifact given to him by the Frost Queen activated.
"[Uller's Mighty Ring]!"
The ring suddenly imbued into Argus the power of an Ancient Titan, Uller! His strength exploded up to ten times its original values, as his body size suddenly became twice as big. His fists reached Lancelot and then…!
CLASH! CLASH! CLASH! CLASH!
Lancelot was being overwhelmed! Countless fists started tearing down and freezing his entire body constantly. His constant regeneration was almost incapable of keeping up with the damage dealt!
"[Divine Blizzard Axe]!" Argus swung his axe twice, unleashing an x-shaped slash made of divine power and ice energy, clashing against Lancelot.
Lancelot's entire body ended being sliced in two, as he fell down into the floor, covering the entire floor with his gusts and blood.
"Hahhh… Hahahah…" Argus started laughing, standing up barely. His entire body was covered in the many wounds that Lancelot had inflicted upon him. "I-It is my victory…"
Seeing the insect's body being sliced in two halves, there was absolutely no way for him to remain alive… Well, the thing is, Lancelot was never alive.
His soul and body were sliced in two, but so what? As long as he had enough supplied Mana from Maria, he stood back up again as two. From their wounds, abyssal dark auras emerged, as their other halves grew a chimeric body made up of many insectoid parts.
"It is not over… NOT YET!" Lancelot roared, with barely 20 seconds left, his two halves leaped towards Argus, catching him off guard!
"W-What?! You're still alive- AAAGGGH…!"
Argus was sluggish and tired, and Lancelot used this opportunity to attack him from front and behind. Sleipnir pierced through his chest and unleashed an explosive impact of black flames, while from the back, the other half of Lancelot aimed for the Ice Giant's head.
"U-unnggh…! Y-You damn insect!" Argus was about to crush Lancelot, but the other half behind him suddenly began glowing brightly, turning completely red as his very soul started flaring like flames…
Argus entire head was blown to bits as he screamed in agony, by sacrificing a piece of his body and soul, Lancelot managed to defeat the undefeatable Ice Giant, as his enormous body fell over the ground.
This time, to never stand back up again.
The transformation ended as well, as the fusion between Maria's Ego and Lancelot ended, Lancelot's wounded body and soul fell over the floor.
"Lancelot!" Maria cried, quickly beginning to heal his soul and body.
