Izan asked Eren "First what is that thing on your waist and what does it do" Eren responded "it is three dimensional maneuver gear and it shoots cables and is propelled with gas" Izan and Hellflix nodded to each other and then looked at Eren. Izan spoke "you want to see how we fight titans" Eren seemed curious "sure I'll be glad to see you try to take down a titan by yourselves" Izan and Hellflix looked to each other to and Izan said "alright then, let's do it!" Izan and Hellflix ran toward the fourteen meter class titan. Eren watched eagerly to see if they would need any help. But to his surprise they were perfectly synchronized, Izan nodded and Hellflix picked up his pace. Izan took three steps, Izan jumped then stomped. Hellflix grabbed Izan's back plate as Izan stomped on the hard ground, and then a huge gust was produced. Dirt and dust that lay there hovered off the ground. Out of that dust Hellflix and Izan who flew fourteen meters into the air, Izan reached back and grabbed Hellflix's arm, then Izan threw Hellflix toward the titan. As Hellflix was spinning toward the titan he thought about what one of his childhood friends asked him "why do you call yourself Hellflix". He answered that question in a yell "I do it for the suffering they have caused me; I do it to inflict HELL!"
Hellflix bit into his hand causing an explosive reaction, out of that reaction emerged a body… but it wasn't his own, it was a titan. This titan yelled demonically "GUILLOTINE", it spun and collided leg-first into the fourteen meter titan, crushing it instantly. Levi squad arrived to see the titan speak they thought "This titan was the first to ever speak". The titan landed and grasped the ground with its left hand and caught Izan in the right one. When it stood up it was twenty meters tall and had talons on its fingertips and toes. It also had only four toes on each foot which was strange. Besides that it looked very similar to Eren's titan. The members of Levi squad decided it would be best to study the titan, so they attempted to catch it. The titan placed Izan on its shoulder and then glanced at him. "Look out!" Izan said as he pointed to the incoming soldier. Then a large group of titans appeared behind Hellflix's titan form
Izan called Hellflix out by name "Marcus, take care of those titans, I'll take care of that soldier…" Hellflix then responded "I don't take orders from you, but this time I'll let it pass… I'm on it!" Hellflix put Izan down and stormed off to stop the titans. Izan waited for the right moment to grab the cables and jump to keep the soldier from attacking Hellflix's titan form. Izan heard the cables fire off and thought to himself "now!" Izan then reached out and felt the cables in his hands. What he didn't realize was that by holding the cables he was adjusting the trajectory of the soldier directly at him.
When he realized he didn't jump, it was already too late; the soldier was about to collide with him. Izan moved his right leg to comfort the blow and twisted his foot sideways to weaken the resistance from the blast. Then they collided and Izan wrapped his arms around the person so if he fell backwards the person wouldn't get hurt by rolling across the ground. Izan slid backwards with the person in his arms when he stopped moving he realized who it was… it was Mikasa. She looked unhurt; besides she looked very comfortable, a little too comfortable. To break the silence Izan asked her "are you okay, sorry but I couldn't let you attack my cousin, as you can see he's trying to protect us"
Izan received no response and looked at Mikasa's facial expression, she looked very calm, and it was like she didn't know they were on an expedition. Then Mikasa looked up and asked "why did you stop me from attacking that titan, we need to capture it" Izan didn't feel like explaining himself again so he said "that titan is my cousin" she asked "how can he be… was he born human with the ability to turn into a titan" Izan responded "no he was injected with some sort of liquid when he was nine years old that allowed him to become a titan". Mikasa spoke "okay but if Eren sees him he'll…" "Oh, Eren's just over there watching us fight. He saw us preform the guillotine maneuver". Izan asked Mikasa "um… are you going to let me go, because my arms aren't around you anymore" when Mikasa realized his arms weren't around her she backed away, turned her head down and remained silent Izan lifted her chin up, he saw that she was blushing and said "oh… I uh…I'll go help my cousin out, and you should… go tell Levi… to uh… call off the attack".
Izan turned around and ran off to Hellflix's defense. Before Izan arrived, Hellflix knew Izan was soon going to reach him, so Hellflix began using stronger attacks. First he clawed one titan's nape and killed it; he then punched the next to push it back, and side-kicked three more in the leg to trip them. Hellflix stomped on their necks to execute them. That gave Izan enough time to reach Hellflix. Hellflix picked Izan up and nodded. Before then they prepared to kill the incoming titans, Izan spoke "Hellflix get the two in the front, I'll take the last in the rear. Let's try Hailstorm protocol".
Hellflix then threw Izan into the air long enough to make a fist in his titan form and then punch Izan's boots, which launched Izan thirty-four meters off the ground. While Izan was in the air Hellflix decapitated the front titans by slicing with his talons. Izan reached over his shoulder to grasp his sword and took it out of its sheath. The weight of the sword made Izan's upper body turn toward the ground and that's what Izan wanted. Izan made his right hand into a fist and squeezed his palm padding together. Then a large blast of air from his boots sent him toward the rear titan. Izan spun around clockwise; he was falling so fast that he was going faster than the best three-dimensional maneuver gear. Izan was a blur to the guards and Mikasa who told the guards to watch Izan's combat style. The rear titan fell shortly after Izan disappeared… and on the ground laid Izan. Izan stood back up and checked for any injuries. He noticed that Hellflix's titan was crouched and steam was coming out of the other side. Izan walked to the other side and saw Hellflix take off all the muscle tissue attached to his body. Hellflix jumped off the titan's body and shook before saying "that's the only part I hate about the release".
The members of Levi squad approached the two. They looked surprised yet angry at Izan. Izan asked "now what did I do", and Levi responded "you left from the patrol, disobeyed an order and we could charge you with deserting the Survey Corps for that". Izan responded "oh but I didn't do either of that, I was being watched by Eren over there… remember you sent him to watch me" Levi looked to the balcony of the center building and saw Eren "I see, do not leave the formation again or I will have to call it deserting, do you understand me". Levi then looked to one of the soldiers behind him and said "bring Yaeger to me I need to confirm that he has been 'watching' Izan", Levi looked to the man that stood beside Izan then asked Izan a question "Izan, who is this then"
Hellflix answered the question before Izan could say a word "my name is Marcus Sypht but people call me Hellflix as a nickname. I'm eighteen years old". The area fell silent then Hellflix said "I'll go to my platform now, Izan if you need me… you know where to look", he jogged away into the woods. There was a stare down between Izan and Levi then Eren walked behind Levi and asked "you wanted me for something". Levi looked at Eren and asked "yes I did, were you watching Izan when he was fighting the titans" Eren answered "yes I watched all of it, even Hellflix's transformation. They are more skilled than any of us when it comes to killing titans. It also appears that Hellflix has complete control over his titan's body when he transforms, he even has the ability to speak". Levi nodded his head and asked "are you willing to act as a second witness for Izan's battle skills since we do not have any documents written" Eren looked to Izan and then back at Levi and said "yes, but who is the second".
Levi answered the question "Mikasa Ackerman is the second witness", they looked back at Izan who wasn't at the place he was standing previously. Eren asked "Izan, what are you doing" Izan responded briefly "I'm looking for my sword, it appears to have fallen from my hand on impact and I can't find it" Izan looked to a tree and saw it stuck in the dirt in front of it. Izan spoke lowly "ah there it is", Izan walked to the tree, grabbed the sword and pulled on it. The sword was removed from the dirt with ease and Izan sheathed it. Then Izan walked past the group, he was humming a tune and walked the building that he tied his horse on. He untied the knot and lifted himself on the horse. Izan joined the group who were already on horseback and they all left to regroup with formation. Except for one person… Hellflix, who sat on the edge of his platform and watched them leave the opening.
