It wasn't the loud shouting in his ear that woke Trex, saiyans were known for their ability to sleep through amazingly loud sounds, but the siren next to his head combined with an impact on his stomach had Trex sat up gripping his middle and breathing heavy,
"Ahhh!"
"Get up, training begins now," a voice yelled,
Trex was then dragged on to his feet and out of the barracks into the surprisingly nearly fixed up courtyard of the eleventh squad barracks. Multiple shinigami were standing in a grid formation at attention, the third seat Ikkaku was standing at the head of the group facing them all with his zanpakutou drawn showing basic attack movements with it. Trex was pushed into an empty slot near the edge of the second row.
"You rookies, follow my movements," shouted Ikkaku, turning away from the group he took up an attack stance and waited, everyone else drew their zanpakutou and copied the stance,
"Follow me newbie," cried Ikkaku without turning round,
"Pst, newbie means you," said a man next to Trex out of the corner of his mouth, so Trex copied the stance and drew his own zanpakutou. After a few hours of copying attack forms and stances Ikkaku broke form and allowed everyone to rest, but Trex stayed standing,
"Didn't you hear me? Have a break,"
"No, I can keep going, if this is what you call training,"
"Listen, Trex was it? Like I said yesterday, when the captain and vice captain aren't around I'm in charge,"
"Well if you're in charge, shouldn't you test me to see how far I can go? Sir,"
By now some rookie shinigami were watching the man brave enough to stand up to and mouth off at Ikkaku, one of the few seated officers to obtain bankai.
"You should watch yourself, you're not even a true shinigami so watch where you tread, unless you think you can take me," said Ikkaku retaking a fighting stance with his zanpakutou in one hand and its scabbard in the other. Trex and Ikkaku stood off for over a minute before being interrupted by a glittering butterfly flying between them,
"Ikkaku, you'd better answer that," said Yumichika stepping out from the crowd,
"Fine Yumichika, we'll finish this later newbie," Ikkaku let the butterfly land on his finger and received its psychic message,
"Looks like Captain Commander Byakuya want's to see you newbie,"
After being escorted down a series of corridors in a very large building, Trex found himself back in the same room he found himself in when he had first woken up in soul society.
"It's nice to see you've made a good impression on your taichou, Kenpachi thinks you have a lot of skill" the voice belonged Kuchiki Byakuya acting commander of the thirteen squads, Trex had been briefed on his identity and the sort of respect he was expected to show the commander, Byakuya stood behind a desk that faced the door Trex had entered through,
"He has even asked you to join a Hueco-mundo mission to test you in the field, I of course cannot allow this but I will let you do a patrol mission if you want,"
"Hueco-mundo? What the hell is that?"
"It is the world in which hollows are born and live, and before you ask, hollows are creatures that peoples souls become if they do not cross over properly,"
Trex's confusion only grew with this new information, and his expression reflected this fact,
"I shall send you on a patrol mission, you seem like someone who will learn more by doing than by listening anyway," said Byakuya sitting down and filling in a sheet of paper,
"Take this to your third seat and you will be shown where to go and what to do,"
Trex followed the instruction and took the sheet to Ikkaku who's reaction was a loud cry,
"Whaaat! You on patrol," however, Ikkaku took Trex to Seireitei's bordering wall and sent him through a senkaimon to the real world.
Nearly the second Trex arrived through the senkai gate a group of hollows jumped him and the two shinigamai he was with, taking them down was no trouble but the shinigami in charge had thought that Trex acted recklessly, attempting to take them down himself and so had gone on report which captain commander Byakuya had read with irritation and chose a punishment that Trex found most distressful,
"What? You're sending me to school!" cried Trex in anger,
"You will go to the academy," said Byakuya facing away from Trex, the report in hand,
"I thought that I went on that pathetic patrol because I was good at fighting,"
"That much is obvious, but you have no self control, at least taichou Kenpachi has that much, you shall learn to control yourself and not put your fellow shinigami At Risk!" Byakuya shouted the last two words to keep Trex's attention,
"How long am I going there for?"
"As long as it takes, 'saiyagami', now go, the academy's waiting for you," Byakuya sat at his desk and ignored Trex until he left.
"Trexy!" the name rang irritatingly in Trex's ears as he followed the voice through the corridors of the academy he was now a part of, Kenpachi had told Yachiru to show him around the main classrooms before taking him to the combat field where Kenpachi was leading a one off session to 'break in' Trex to the academy.
"Shut up brat!" Trex cried after Yachiru, more annoyed after this seventh time being called 'Trexy' than he had been the first.
"Don't be mean or Ken-chan will kill you!" Yachiru shouted with a large smile before disappearing round what seemed like the hundredth corner leading to another corridor. Trex had looked in on active classes for reiatsu training and Ken-do, not much else seemed to be taught that didn't relate to the social structures of soul society, and he didn't much care about that.
Finally the corridors seemed to end and Trex stepped out into a large grassland, a gravel path lead from the double doors toward a thicket of trees, to one side of the field was an array or training dummies and wooden post's, and to the other were three tiled combat squares.
Kenpachi was standing in the middle of the closest five metre square combat ground and a grin spread across his face as soon Trex stepped through the door,
"All right Trex, this fight will truly test you because you won't use any reiatsu attacks, and we will be in a sealed barrier so there's nowhere to run," Kenpachi's grin somehow seemed to grow wider,
"(Pft), like I would run from you, and I don't need reiatsu whatever it is," Trex took up a stance ready to attack,
"Reiatsu is the energy you used last time idiot!" shouted Yumichika who had appeared in the crowd slowly surrounding them.
Kenpachi drew his zanpakuto and stood firm, "Well, draw your zanpakuto,"
"It's just a sword, I don't need it to Take You ON," Trex yelled the last of the sentence as he lunged forward propelling himself with ki and throwing a fist at Kenpachi's chest, the punch was blocked by Kenpachi's blade and a large hand came down to smash him into the ground.
The hand seemed to pass through Trex and there was a brief look of confusion on Kenpachi's face until the top of a foot collided with the side of his head knocking him off balance,
"Ah-huh, using shunpo, not true combat but at least it isn't using reiatsu," Kenpachi then swung his zanpakuto slashing at Trex's face, luckily he only cut a few strands of hair as Trex back flipped toward the edge of the ring.
As Trex stopped at the edge of the ring he felt a wall behind him, but when he looked there was nothing there. Four shinigami had stepped out from the crowd and were standing at each corner with the palms of their hands facing the centre of the ring, "They must be creating the barrier Kenpachi mentioned"
A hand grabbed the front of Trex's kimono and threw him back to the centre of the square,
"Don't get distracted now, I'm your opponent and I don't go this easy very often,"
"I never asked you to, I don't need you going easy on me,"
In a fit of rage Trex attempted to fly up but his head hit against something very solid, again an invisible barrier prevented him from moving to far away from the arena, "This is annoying," said Trex and he threw a solid punch at the barrier above him, it shattered like translucent glass and Trex flew high into the sky before speeding back down and collided with Kenpachi with great force.
As the dust cloud settled the surrounding shinigami stared at Kenpachi holding Trex off the ground by his kimono, "Nice try saiyan, I like you, but you're not going to win a fight on pure brute strength, only I can pull that off, and you're not even using your zanpakuto,"
"I know it takes more than brute strength to win in battle, it takes more than the power to back up that strength, and more than the courage to fight in the first place," Trex coughed a little between words to cope with the thudding pain in his head, "It takes all those thing's and the spirit to go on, with will to win, that's what it takes to win," Trex began to glow, Kenpachi looked at him confused, then looked down at Trex's up turned hand.
From it flew a white ball that crackled and shone like fire, it hung in the air casting a faint glow over the surrounding area, all the shinigami in the training ground looked up at it some in awe, and others bedazzled.
Kenpachi dropped Trex for a moment, then looked down at him.
Trex's eyes had turned pure white, he was beginning to sweat and his tail was failing around, others began to look back at him as Trex began growing hair all over his face. His face grew a snout and his eyes became scarlet red. Trex began to grow, more and more, bigger and bigger, his clothes grew with him, and sharp teeth sprouted from his mouth. By the time the transformation was over Trex had become a colossal tailed gorilla the size of a five story building with arms as thick as tree trunks. He let out a great roar and looked down at Kenpachi,
"STILL THINK YOU NEED TO GO EASY ON ME!" Trex growled in his new voice.
"This is going to be fun," yelled Kenpachi with a large grin before laughing in amusement.
Before Kenpachi could defend himself Trex's foot kicked him into the air sending him spinning. Trex's large hand grabbed Kenpachi out of the sky and raised him to Trex's eye level.
Kenpachi appeared to be disoriented and his head was lowered.
"You don't look so good, 'Kenpachi Taichou'," Trex chuckled before laughing.
