(Drake)
Natas had to shield his eyes from the brilliant magenta. As he kept his eyes close, Natas tried to shoot out dark magic at his son. But the explosion destroyed puny by comparison attacks. After a bit, the magenta cleared and... there was nothing ok about what was standing there. It was Drake. The thing is..., he was split between his monster and human halves. His eyes were magenta w/ black irises that were full of madness. Drake's mismatched hands and feet were now more vascular than usual, and his mouth was... smiling big and wide as tears fell from the eyes. Finally, a magenta crack had appeared above the monster half's eye. The big guy also appeared to be... glitching?
"Hahahahahaha...," Drake/Alter laughed distortedly.
At this, Natas couldn't help but bust out laughing.
"OH MY FUCKING GOD! AND I THOUGHT YOU LOOKED PATHETIC BEFORE!"
Suddenly, w/ blinding speed, spliced Drake rushed at Natas and torpedoed him into a car! Immediately getting up from the wreckage, Natas readied himself.
"SO BE IT, YOU WORTHLESS CUNT."
FINAL FIGHT START!

As it turned out, Drake gave Natas a surprising amount of trouble. Despite the years of abuse and Natas' horrible power, Drake, shockingly, somehow overpowered him! Drake moved lightning fast, combining his human magic w/ his monster weaponry to strike at Natas. Despite being able to block some hits, Drake inhumanly followed the first hit w/ a swift second that Natas couldn't dodge! As a result, Natas was, ironically, the one to be tossed around the block like a ragdoll. When he tried to use his illusion power, Drake would simply counter this by using his own magic to destroy the fake void each time. At some points, the father and son would charge at each other, covered in energy. Each time, though, Drake still overpowered his dad, slammed him down on the ground, and threw him aside! Drake would also laugh brokenly as some more blood kept gushing from his wound. Whenever Natas tried to attack his son, spliced Drake effortlessly dodged each blow, even from behind, much to Natas' satisfying frustration. Eventually, though, Natas finally had enough. He had many wounds from head to toe, and black liquid flowed from them. Natas, for once, was fuming. To him, this situation was all wrong. Drake should be the one getting beat within a quarter of his life, not Natas!
"ALRIGHT, ENOUGH GAMES, YOU DUMB FUCKER. YOU AND I BOTH KNOW THIS ISN'T RIGHT. LET'S END THIS, RIGHT, RIGHT NOW!"
Natas then began to charge his dark energy into his hands. Drake, cocking his spliced head, did the same. After a bit, the two released all of their magic into one, all-out blast, Drake's magenta, and Natas' bloodred. While at first there was a bit of a struggle, Drake's power quickly overwhelmed Natas'! Natas, alarmed for once, tried desperately to hold the blast back w/ everything. W/ Natas out of options, Altered Drake thought about what he was fighting for. W/ intense, multicolored lenses, he vividly remembered everything he and Andrew had gone through and how Andrew never gave up on him. He also remembered all the horrible things that Natas had done in his life that he could recall. At this, spliced Drake's broken smile stretched even farther.
"Time to go, dad," said Drake/Alter.
Suddenly, electrified bladed chains burst from the ground under Natas. Before he could notice them, they immediately struck right his skull! The shock of this alone was enough to cause Natas to falter. At this, Altered Drake's blast ANNIHILATED the faker. Natas' body was seared from the magic, and he experienced the worst pain imaginable for a while! After a bit, though, the attack ended. Where Natas once stood, there was a black skeleton w/ dark goo covering it. Once the chains disappeared from its skull, the vile thing collapsed. Altered Drake viewed his handiwork blurrily, rocking back and forth.
"Andrew... we... did... it..."
Then, Drake collapsed himself, the human part of him turning back to the monster part. Blood now poured from the crack in his head...
