The Inter-Dimensional Demon King: Trigon

Deciding to leave Enchantress to Kori and Raven, Raiden's focus turned towards Trigon 'This is a terrible match-up for me now, Scáthach's powers are good against gods, not demons, especially if they are human-sized, but this guy is giant' 

(Indeed this is a tough opponent, but you must surpass the limits of my body, it would seem the enemy has discovered one of your weaknesses) spoke Scáthach as she pointed out the fact that Raiden's weakness was discovered, this confused Raiden and he asked 'What do you mean Weakness, How exactly did they exploit a weakness of mine ?'

(That Witch that goes by the Name Enchantress, she chose to appear in front of you first, before she called upon this Giant, meaning the system recognized her as the enemy, transforming you into my body, the optimal servant to defeat her, I already know you are aware of this, but the fate system always transforms you to the appropriate servant for the occasion, unless you chose to transform on your own, and I have reasons to believe that your enemies have discovered that) 

Hearing Scáthach words, Raiden realized what she has said 'I see, so she intentionally showed up first, had it been Trigon, then a stronger or perhaps in this case, a more destructive servant would have appeared' 

(Yes, the system responds to your desire, whenever you desire something, the system is always responding to you) 

'Wait how do you know all of this, this is the second time I transformed into you, but somehow you are acting like you know everything about me' said Raiden in confusion, she was aware of more than she should have (Focus on the battle) as she said that a fiery light beam of fire was released from Trigon's head, from between his horns, Raiden easily dodged the attack, but realized it instantly (One hit from something like that, and I'm dead)

"Ho? Is this the Savior she chose, I expected a lot more from you, But I don't see the Wizard, so it is true, you cannot choose who you transform into. This is Boring, when that Witch guided me back to Azarath she promised that I would have my revenge on that Mage, but with you unable to bring him out, it's all for naught, DIE You worthless human" At his word, power surged through Trigon's hands as his aura increased, Red heating energy surrounded him, he then followed Raiden's movement and released a punch in his direction, of course with Raiden's speed and the fact that Trigon was a giant, he was able to dodge the punch, but the aftermath of it was a different matter

The punch created an earthquake-like vibration that destroyed everything in its wake, forcing Raiden to jump instead of running, then, creating dozens of spears, Raiden launched them toward Trigon's face, aiming for his eyes

"YOU ABSOLUTE TRASH" screamed Trigon as his eyes started to hurt, he used his hands to close them, before quickly removing them and aiming his Horn Blast toward Raiden again 

'The speed of his recovery is insane, It's like I'm a mosquito, any damage I deal isn't significant, or heals too quickly' thought Raiden, to which Scáthach supported him saying (The Primordial Runes will be useless here as well, any quick Rune won't do much damage, and biding time to release a full powered Rune is impossible while facing him) 

"You know what, fuck it, Let's be a pest, a Mosquito that bites constantly," said Raiden as he jumped on Trigon's arm, then stabbed a part of it, opening his cut, he griped the spear and dragged It all around his arm towards the shoulder, with enough speed and power, a massive wound opened up on Trigon's Arm

(Now Raiden's! he's focused on protecting his ARMS!) screamed Scáthach Inside his mind 

"Alright, this is My Chance

Thrust and Penetrate! 

GAE BOLG"

The Spear of Curses, bending the laws of causality and ensuring a hit on the enemy's heart no matter what, one could only resist this if they had A Rank Luck stat or another Law bending Noble phantasm

Raiden's speed increased as his Spear turned blood crimson, and pierced Trigon's Heart, Raiden's entire Body flew inside the flesh with the spear, he found himself filled with blood outside Trigon's back as he turned around towards Trigon shocked 

(Raiden! This is ...) 

"He doesn't have a concept of a Heart..." said Raiden, the Noble Phantasm worked on all living entities that had a heart, but Trigon was different, an Entity created from dark energy, although he was once a mortal, and a living entity, the Trigon that Raiden was facing was (An Amalgamation of Dark Energy, This creature is Akin to a Beast)

"AHAHAHAHAAH" Laughed Trigon as he turned around to look at Raiden, his heart was slowly healing, until it completely regenerated "Playing with you is Fun, I'm Having quite the fun seeing a bug struggle against me, Boy, why don't you submit yourself to me! It's a waste to Kill you, you could be a good messenger for me, I'll let you and My daughter live together as well, your job would be to prepare worlds for me"

"So Generous of you, I'm quite touched, but I'm not out of options just yet, if that didn't kill you, I'll just have to get you with something much more powerful right ?" Said Raiden, as he spun his spear around and pushed his hand forward "If I can't Kill you here, then

I will show you what lies beyond the world.

 I will lock you away in the darkness from the age of the Gods. 

Tremble, freeze, and shatter into pieces! 

Gate of Skye!" 

Inside the Crimson Clouds a gate was Opened, brimming with the energy of death, the Gate's size was almost half of Trigon's size, the Gate dropped down as the two doors opened together, creating suction energy, devouring the land of Azarath, the buildings, and trees started to flow inside the gate, whatever gets in, either turns to ash or withers and dies, since the Gate opened behind Trigon, he too was Sucked, but due to his Massive size compare to the gate, it couldn't completely take over him, making it so that it locked him In place instead "A LAND FILLED OF DEATH! So that was your trump card AHAHAHAHA" 

'It's Not working! Is it due to his size !' thought Raiden, but then Scáthach corrected him (No, Size doesn't have a role to play, the gate of Skye doesn't discriminate, Raiden, it's his Authority, he is one of the underworld's Kings, Equal to my Rank, his Authority is resisting the gate's effect 

'But Still, This isn't too bad, right? the Gate is holding him in place, he can't move, so I'm free to attack him, the problem is that my attacks won't deal any damage' thought Raiden (NO!!! CAREFUL Raiden) 

"Gruzz'tul dharokan belzum, mortalketh! Lohk'tal in belk'narok mor'k'vun!" ("Feel the flames of my fury, mortals! Burn in the fires of eternal torment!") As Trigon's demonic Spell casting ended, huge Pillars emerged from the ground, filled with flames, the entire area surrounding Raiden turned into Flames, forcing Raiden to dodge the pillars and escape the entire area

"You Foolish Mortal, You seem to have a misunderstanding here, While this Gate is truly sinister, it can't do much other than lock me in place, but to defeat you? I don't even have to lift a finger, perhaps you thought me playing with you earlier was I taking you seriously, Honestly, I didn't expect such Hubris from a Human, I'm the Inter-Dimensional Demon of Hell"

Then as he watched Raiden dodge he laughed and said "Yes, entertain me, dodge the pillars, but what about the ones from the sky?

Observevul krashtaz'dek ma'korun! Vashka'zeth varith'tan inan'tal, zik'narok va'lashkun teth'ruk korun!" ("Behold the might of the tempest! You are but a leaf in the wind of my wrath!")

a swirling storm of dark energy enveloped the skies, unleashing bolts of lightning and torrents of shadowy wind upon Raiden, dark lightning bolts dropped from the skies, Raiden's speed increased trying to dodge the flames of hell from the ground, and the dark bolts of the skies 'THIS IS INSANE! He wasn't this strong last time, did something change ?' 

"AHAHAHA DANCE MONKEY, Entertain this Great conqueror! AHAHAHAH Oh I wished you had brought that Wizard back Again, last time I couldn't go all out, fearing killing my daughter and losing the last remains of Azarath's energy, but that Witch from Earlier! She's truly a worthy servant, she brought me a sacrifice of a thousand Humans! Enough to fill my energy up for this battle!" spoke Trigon, as he remembered how the Witch, Known as Enchantress used her magic to guide him back from the abyss, then she sacrificed a thousand souls in his name, revitalizing his energy, saving him the trouble of having to go to a long slumber

"Damn it 

Gáe Bolg Alternative: Hundred Soaring Spears of Piercing Death" As Raiden Released yet another Noble phantasm, hundreds of Spears, similar to Gae Bolg in Rank were created in the skies, aiming at Trigon, due to him being stunned, the spears each pierced parts of Trigon, His eyes hands mouths, chest, Trigon was filled with spears 

"AGHHHHHHHHHH DAMN YOU! You Garbage imbecile of an Inferior being! I will end you now! Enough Playing Around 

"Infernalth koruun, zel'narok lohk'tul! Veth'kraznak amal'narok va'thul keth'korun! Zaltharok Vash'krith! ("Into the darkness you shall fall, crushed by the weight of your own despair! Abyssal Annihilation! ")

Above Trigon's Horns, Not one, but Three spheres of Darkness were created, Each the size of a massive building, swirling around each other, the Spheres started to grow bigger and bigger, and sparks of electricity and dark energy were connecting between them until they merged, than the Dark sphere started to condense into nothing

*ZIIIIIIIIIIIIT* [Author's Note: Imagine Midir's Laser from DS3 but faster! much faster]

In an instant, a laser-like Dark power was released, its speed broke the sound barrier, and with Raiden distracted with the Pillars and Bolts, dodging this was impossible, hitting him right in his chest, engulfing him, the Abyssal Annihilation was the ending move for this battle 

Surviving it was a miracle, but To completely go unscathed was impossible, Raiden's form reverted to his normal self, but he was missing his right arm, his right eye was completely devastated, and half of his abdomen on the right was gone, the attack was a complete success, destroying half of Raiden's right side
