Trex's eyes opened slowly, as though he had just woken from a dream. He sat up and saw half a dozen shinigami standing around his fallen halberd, one shinigami reached out to pick it up and quickly an orange flame lashed out at his hand causing the shinigami to swiftly pull his hand away for fear of it getting burned. Trex looked around for Yourichi and found her talking to a shinigami in a white coat with a black and white painted face, and blue hair styled in an odd fashion,
"Cat woman,Yourichi," Trex called out to Yourichi,
"Ah, the specimen is awake," The shinigami with the painted face said and began walking over to Trex, "I have been wanting to look at you ever since I heard rumour a lowly shinigami from 4th squad transformed a non-earthly creature into a shinigami and it went strangely,"
"What the hell are you?" Trex asked nervously as this man was putting his face closer than he was comfortable with,
"Not that introductions are important to me but I am Kurotsuchi Mayuri, Captain of the twelfth squad and head of the research facility, now could you come back to my lab so I can dissect you,"
"Aahhhh!" Trex cried out in an uncharacteristic moment of fear and scrambled away from Kurotsuchi,
"Kurotsuchi!" Shouted Yourichi, "Leave him alone, there are bigger questions that need answering right now than how his physiology works,"
"If you say so Yourichi, Now let us look at this wonderful zanpakuto that has taken the form of our old execution device," Kurotsuchi moved toward the zanpakuto where his subordinates were still stood around it unable to get near enough to pick it up,
"A feisty one are we, well that will make you all the more fun to dissect and study," Kurotsuchi himself then reached for the halberd only to have an even larger flame lash out at him than had attacked any of the other shinigami,
"Kurotsuchi!" Yourichi shouted to get the captains attention, "How was and why did the zanpakuto gain the shape and power of the Sokyoku if it was destroyed all that time ago,"
Kurotsuchi turned to face Yourichi with a grin on his face,
"To be honest Yourichi, not all of the Sokyoku was destroyed, a fragment of it cast off and landed not far from my laboratory, I found it and have been safeguarding it and experimenting with it ever since,"
"You were keeping such a powerful thing hidden from the rest of the Gotei?"
"I did not see why I would have to report such a trivial thing, especially seeing as at the time the Gotei were very much preoccupied with Aizen's betrayal,"
"But why did it fuse with Trex's zanpakuto and return to life in a smaller form?" Yourichi asked,
"You do ask some annoying questions," Kurotsuchi's grin shrank away and he sighed, "All zanpakuto require a shinigami, but the Sokyoku was different because it had the power of multiple zanpakuto's and was created simply for the purpose of executing shinigami who had committed the worst of crimes by our laws, however, when the Sokyoku's body was destroyed and this fragment was all that survived its original purpose was also destroyed, so it's only other purpose could be to serve a shinigami now that it has only a fraction of its original size and power, that is the most logical hypothesis I can come up with in the short time you've given me since this event occurred, Although why it chose this inhuman thing as it's master I cannot say,"
"I see, thank you Kurotsuchi, I will report this to Byakuya in the morning," Yourichi turned towards Trex,
"Well I'm glad someone understands what's going on, because I don't," Trex yelled at Yourichi, "But oh well, I've had enough fun for one night," Trex walked passed everyone to his new halberd zanpakuto, picked it up, rested it on his shoulder and walked away leaving all of kurotsuchi's underlings with shocked faces as he was able to pick up Sokyoku without being attacked by its fire.
In the morning Trex voluntarily joined the rest of the shinigami in their morning training routine. Since the event's of the previous night Trex had been curious about his new weapon that had for some reason become a katana while he was sleeping. After the basic exercises were complete Trex walked up to Ikkaku,
"Hey shiny head," Trex greeted Ikkaku,
"What did you just call me?" Ikkaku pressed his face into Trex's with anger,
"I heard that kid with pink hair call you it so I thought it was your nickname," Replied Trex casually,
"She may be a child but the vice-captain can call me what she wants, but it doesn't mean that I like it," Said Ikkaku stepping back from Trex "Anyway what do you want?"
"I was wondering if we could continue that fight we started before the 'vice-captain' interrupted us,"
"And why would I agree to that? You weren't that entertaining the last time, and without being able to transform your zanpakuto you wouldn't pose much of a challenge once I fully released mine," Replied Ikkaku acting high and mighty with a smug look on his face,
"Well I can transform my sword now, I don't know why but I was able to do it last night, that cat lady Yourichi made a big deal about it with the captain with the blue hair," Trex drew his zanpakuto and looked at it as he said this,
"You were with Yourichi and Kurotsuchi Taichou last night? Why?"
"Yourichi had me doing some training and it looks like it paid off, so are we going to fight?"
Ikkaku stood for a moment considering the offer,
"All right then monkey boy, let's see what your shikai has got," Ikkaku jumped back and took up a fighting position holding his sealed zanpakuto in one hand and the scabbard in the other, Trex also changed to a fighting stance holding his zanpakuto out in front of him with both hands.
With Trex and Ikkaku in position, neither one of them wanting to make the first move. After a few moment's Ikkaku made the first move, stepping forward he put the handle of his zanpakuto to the start of it's scabbard,
"Nobiro Hozukimaru!" As soon as he shouted this a whirl of wind surrounded his zanpakuto and when it died down, in it's place was a long wooden spear with a lethal looking blade at one end and ornamental fur on the other,
"Why did you shout 'extend' before calling your sword's name?" asked Trex with genuine question in his voice,
"It's the way you release your zanpakuto, you say a command related to the the way it transforms and then call it's name, don't you know anything?" replied Ikkaku almost laughing,
"Oh, I thought you just called it's name, I've never actually transformed it, last night it sort of did it itself," said Trex looking at his ordinary looking katana,
"Ha, you are a terrible shinigami, you can't even release your zanpakuto," said Ikkaku beginning to laugh hard,
Trex felt a heat coming from his zanpakuto, he closed his eyes and Ikkaku's laughter immediately faded away, he breathed deep, opened his eye's and a smile spread across his face.
Ikkaku stopped laughing once he saw Trex smiling,
"What do you have to smile about?" Ikkaku looked at Trex with suspicion,
"Hinote, Sokyoku," once Trex spoke these words, flames erupted around his zanpakuto. Once they died down, in Trex's hands he held the black handle of a halberd.
"Did you say Sokyoku?" shouted Ikkaku with disbelief,
"Is that a problem?" replied Trex,
"No, since the real Sokyoku was destroyed," Ikkaku took up his fighting stance again now with his spear, "I don't need to fear its power,"
"You might want to think about that," Trex said,
Trex jumped forward swinging Sokyoku around his head and attacking at Ikkaku's legs, Ikkaku jumped straight up and brought Hozukimaru down as hard as he could. Trex blocked it with the handle of his halberd and pushed Ikkaku backwards. Ikkaku didn't lose his composure fore long, the second he landed he lunged at Trex, thrusting his spear directly forward aiming at Trex's chest. Trex side stepped and began another swing at Ikkaku,
"Sakero!" shouted Ikkaku, and Hozukimaru split in two places with a chain connecting the three pieces of the spear, the blade swung sideways coming round to attack Trex's face.
Trex very quickly ducked down turning his jump into a forward roll causing him to almost collide with Ikkaku. Ikkaku jumped out of the way and re-swung his three part spear towards Trex's back while he was still crouched in his roll position. Trex caught on quickly and swing his halberd behind him knocking Ikkaku's spear to one side. Trex swiftly stood and turned to face Ikkaku to find him readying himself for another attack, his spear was in one piece again and it once again flew at Trex's chest. Trex knocked it away just before the blade could hit him, now that he knew the power zanpakuto's could have he didn't want to take any chances despite the fact he was wearing his saiyan armour.
Taking up a new stance, Trex ran toward Ikkaku but flanking to his right, as if to strike at Ikkkaku's side. Ikkaku saw Trex's plan and very quickly turned left to face Trex every step of the way so that he could guard against an attack at any moment. Suddenly Trex lunged at Ikkaku and then disappeared, Ikkaku had already started to block against the attack and couldn't stop himself.
Trex reappeared behind Ikkaku and swung Sokyoku upwards catching Ikkaku across his back, the momentum from the attack knocked Ikkaku forward just enough to make the cut from Trex's blade quite shallow and not fatal.
Blood squirted from Ikkaku's back and he fell to one knee,
"Ikkaku!" Yumichika's voice rang out from somewhere in the training area and a group of shinigami ran over to help their third seat back to the barracks,
"Get Back!" Shouted Ikkaku at the now scared little woman who had tried to pick him up and the three men that stood around him with their katana's drawn, "That was a good shot newbie, looks like you win, This time," and with that Ikkaku staggered towards the barracks with worried shinigami following him unsure of whether they should help him or not.
