(3rd Person POV)
Sitting cross-legged with closed eyes, and floating above the ground was Beat he has been on the inhabited island for two months now, Odin visited on the second week, and he still couldn't control the ozaru transformation, after failing multiple times the only progress was that he could somewhat remember glimpses of the transformation and the emotions in that state, but with constant failures, he became more and more irritated, after thinking for a while he understood that his method wasn't working, so he decided he'd try different things, now he was trying to remember the rage he felt while transformed and familiarize with it.
'I feel that I'm almost there, I can remember everything until a few seconds transformed, with a couple more tries I'm certain I'll get it.'
He thought while lowering himself and eating some fruits, after Frigga's advice and the discovery of the current Earth state, he understood that he wouldn't be in contact with the modern commodities any time soon, so he somewhat calmed down his impatience and began to observe some animals to get an understanding of the island native fruits, and what could be eaten and what not.
After eating the fruits he flew straight to the water to catch some fish, after a few minutes he came back, after gutting the fishies, he made a bubble of ki with the fishies inside and began to roast it increasing the heat inside to sphere, after a few minutes he stored them to eat later.
'I think I have delayed this long enough.' Soon Beat flew above the trees and stopped with eyes closed, concentrating on the ki inside himself he began to feel it, trying to understand it, soon he tried to feel the same around the forest, he fail, repeated and fail again, after a few more tries he saw a weak spark beneath him, concentrating in this spark, it soon turned into a little light, when he got the feeling of how it felt he expanded his mind he saw the dark being illuminated by those tiny lights, he was finally sensing the wildlife ki.
He opened his eyes while still sensing the life forces, he flew to one and saw a rabbit jumping around, he then tried to ignore the small lights, he tried to feel the biggest in the forest beside him, his senses didn't go too far still it was able to detect effectively at least five hundred meters around him, he soon concentrated just in the biggest life forces in the forest, tracking one he flew to it, arriving he put a smile on his face.
"Hello there!" He said landing in front of a dodo, the bird tried to take a step back but was stopped by a hand in its neck.
With a crack its neck was broken, throwing it in the inventory, he flew again and took off to the sea, he flew a little far from the island and began searching for life forces, when he felt something more than four times stronger than a dodo he dived to it, he soon found what he was looking, a shark of around three meters long, quickly closing the distance, Beat swam above its head and gave it a powerful punch in the head.
The shark was instantly knocked out with blood coming out its mouth, while Beat was giving punches and kicks to the water, getting used to the pressure, he ended up making the other shark nearby think that he was a prey struggling, added the blood of the shark he punched and others rapidly approached, sensing life forces coming closer, he quickly took an instance and waited, not even ten seconds and the first appeared, it tried to bit his left leg but avoided easily doing a front flip with an axe kick powered by the spin, completely destroying it's back, although sharks don't have bones, just like every other living being a strong concussive strike can kill it.
Another one came from down when it was at arms reach Beat gave it a downward haymaker to its snout, the animal quickly back off with blood oozing out its nostrils, while Beat was distracted grinning at the sight and amazed with himself being able to fight off a group of sharks, one came from behind him and bite his torso.
"Agghh!!" With a muffled surprised scream he was shaken in all directions by the giant fish.
'Fuck! It's fucking salty!' He thought after accidentally swallowing the seawater because of the surprise attack.
'You fucker!' After having enough of shaking he gave a back elbow making it release him, he flew through the water to get some distance and inspect his injuries, looking down he saw some wounds on his sides where the shark had bitten, it was bleeding a little but not much, with a sour mood Beat glared at the few sharks left and shoot flying in a superhero pose, with his fists closed in front of him, he directly collided into the shark that had bitten him.
He struck it on its side leaving it with two first sized holes but he didn't stop to see the damage he had done, right now the water was beginning to turn red, he quickly flew to the other sharks piercing them with ki reinforced fingers forming a spear-like hand, after killing a few he stopped when he couldn't feel more life forces nearby.
Flying out of the water after collecting the bodies, he took a deep breath and began to think about his past actions.
'I was reckless, I let the blood and excitement cloud my thinking, I'm lucky I was tougher, if not I would've been cut in two be that bite.'
While thinking this he came back to the beach and laid down, with eyes closed he remained that way for a few minutes, then with a grin, he sat up.
"But I have to admit the feeling of power is incredible!"
After laughing a few seconds he calmed down and took deep breaths, after a few minutes he began trying to control the Oozaru again.
On the beach of a remote island stood a gigantic figure of a monkey-like creature, standing at around 20 meters this monkey was at the moment jumping around laughing with a booming voice.
"HAHAHAHAH! Finally! I finally did it!" After more or less one month of his fight with the sharks he finally controlled the transformation, overjoyed with his achievement Beat began to test his new form, he run around with every step making the ground shake creating craters where his feets landed, he then tried firing ki blasts from his hands but he had to concentrate more than normal in doing it, after struggling a few seconds he made a single ki ball.
"Fuck this is hard!" He had read a fic where it was said to be difficult to use ki in the Oozaru form and while trying he confirmed it, but it wasn't that hard, after all, Baby Vegeta could do it, you might be thinking 'but the GT wasn't canon' well the MCU was just fiction to him a couple of weeks ago, who is to say that the GT wasn't an alternative timeline, just like all that Dragon Ball Heroes and the Xenoverse games.
"HAAAHHH!" Back to the test, he tried to fire ki blasts through his mouth and it was the same easy when in normal form, he fired a couple of beams to the air, and then to the sea, just to see the waters part ways.
"Haha Haha this is great," after hours of messing around he began to shrink, looking to the sky he saw the sun glowing on the horizon, completely overshadowing the full moonlight, after weeks without a full moon it started to show itself just a few days ago, today was the first he had used it to transform, it was a challenge to himself, if he couldn't control the transformation he would wake up with the island completely destroyed, but it seems his bet paid off.
"It seems the psychological pressure did the job." With a sigh, he laid down completely naked in the sand and drifted off.

Two more months had passed and Beat had been trying to master the Ikari mode, he had been able to enter this state after one month trying to contain the Oozaru transformation, after this he had been trying to use the Oozaru power without being transformed, it was straining and time-consuming, but after coming with terms that he was so back in time, he began to take it easy, he decided to gain a bit of strength before venturing in the old world, you'll never know what you will find.
'Although this universe's a paradise compared to the comic version, it's still a dangerous world, deviants are hunting intelligent lives, the extra-dimensional beings looking to invade this dimension, possibly rogue wizards, and many other things that have been added to this universe and the fans didn't know, just like the Eternals, the Ten Rings and that secret realm with the soul-eating monsters.'
He wasn't that interested in seeing the history unfold, after thinking he realized that it would be a boring thing to wait hundreds of years to see the changes he already knew, so he began to train while relaxing on the deserted island, he was also a bit apprehensive about meeting the Eternals, he wasn't sure how they will react to him, after all, he wasn't human, he just watched the movie one time and didn't know anything about them of the comics so he wasn't in any hurry to meet them now.
So with his safety in mind he decided to stay a few more months on the island training, not just to better his mastery of ki but his body too, he was steadily getting stronger because of the LSS but at the rate it was increasing, he calculated that he would take hundreds of years to reach the millions in power level without a harsh environment like the canon Broly or the bullshit rage of the OG, it was hard to find ways to train his ever-growing strength, but he managed after a bit of thinking and lot of trial and error.
With five months of his arrival his power was on the three digits, he could lift a few tons of weight with some difficulty, so he made an elevated platform where he could train with tree trunks all tied to his body, he had made some ropes with vines he found in the forest, it wasn't very resistant but after tie a few together it did the job, he tied at least thirty tree trunks each weighing more than two hundred kilos each, he put the trunks beneath the platform so all he had to do was tie it to his body.
It was after a few tries that he had found the most optimized way to tie the makeshift weights to his body so that it didn't obstruct his movements, soon he began making the most famous training ever, push-ups, sit-ups, squats, and running around the island all the while with trunks tied to his body.

"...If I, huh... had a... huh... fucking huh... gravity machine...Huh huuuh!... I would just have to push a button, but no! I had to be sent to the fucking Iron age!"
Beat angrily shoots out while doing push-ups with one hundred trunks tied to his body, after a few sets he sat on the platform while panting, he frowned while looking through the small opening beneath him where the ropes pass through, 'I won't be using this platform for much longer, there wouldn't be any space left after I put more weight than that.'
With a deep breath, he murmured, "I wonder if Phastos would make a gravity belt or something if I asked him...nah, even if he did Ajak wouldn't allow it." After another sigh Beat continued his training, always putting more trunks when he felt it was getting to ease, he decided to continue this workout until he felt that he was strong enough or when the quantity of trunks he had to prepare became to annoying to bother.

In the distance you could see an island, floating above the island was hundreds of tree trunks with several different sizes, with a great number being more than four hundred kilograms and a few even more, it was all tied to a boy of no more than 160 cm or 5'3'', lifting without problem more than a hundred tons, you could see his bored face while he did this repetitive exercise, until he finally snapped.
"That's it! I'm done, I'm sick of this Island, I wanna see humans! This shit don't have any effect." Saying this he snapped the ropes tied to his body, and before the trunks could fall to the ground he grabbed it by the vines, and began spinning it around himself, after spinning a dozen times he let go with scream.
The trunks all tied together made a parabolic trajectory crashing a few kilometers away from him. "It's always unbelievable to see how much strength I really have, I thought it would become boring after some time but it's still fucking amazing!"
Letting out a sigh he flew up, easily breaking the sound barrier, he flew up until he could see a giant island in the distance, 'It has been a year... truth to be told I'm scared of meeting those people, but if shit hits the fan I'm confident in protecting myself... or running.' While thinking that he saw the sunset in the horizon.
