Several months passed and despite Jewels many humorous interruptions Broly continued to train his Ki Sense and Ki assiduously creating a firm foundation for his future. In addition to training his Ki Sense he had taken an interest in observing the lessons taught to the handpicked Saiyan infants with high potential chosen for special training. Although the majority of what they were taught was completely wrong and wasted the majority of their potential, hindering their bright futures, there was a few things he learned that were quite useful, such as flying, aerial combat tricks, and most importantly racial specific techniques for despite looking like an Earthling (if you ignored his magnificent tail of course) he was in fact a pureblooded Saiyan of the purest bloodline. The most interesting of these few specific techniques was the Power Ball technique.

Like all warrior races who belong to a special bloodline, Saiyan are born with their own special trait, namely a brown monkey-like tail which gives them the unique ability to perform The Great Ape Transformation. A Great Ape is essential the royalty of all primates and as such it towers above all other primate species having a monstrous height of more than a 100ft while its body possesses the superior physical characteristics from multiple different primate subspecies. Its face although appearing mostly similar to that of a gorillas possess the maw and frontal features of a mighty baboon with blood red eyes and a mouth lined with razor-sharp teeth. It's immensely powerful body has a prominent and defined musculature build coupled with a long girthy Saiyan tail and is entirely covered in dark brown and black fur excluding parts of its face, its hands and its prehensile feet which are covered with an opaque leathery black skin.

A Great Ape's power level is equal to the Saiyan's power level prior to the transformation multiplied by ten and surprisingly despite the massive increase in size the Saiyan remains as fast and agile as they were before the transformation. Despite the limitation of most users losing clarity of thought and going berserk, since most Saiyan use it only as a trump card during combat with a powerful foe they don't really consider it a weakness at all. In fact, as Saiyans mature, they can potentially be taught how to reign in their berserker instincts and retain normal cognitive functions as Great Apes.

In order for the transformation to take place, the Saiyan needs to have an intact tail, as the glands responsible for initiating the transformation are located exclusively there. The Saiyan also needs to absorb at least 17 million zeno units of Blutz Waves through the eyes to initiate the transformation. Unfortunately Blutz Waves are found only in sunlight reflected by a moon. The Power Ball technique is a technique developed and used by Saiyans to create an energy sphere that mimics the presence of a full moon.

By combining Ki with the planet's atmosphere, a sphere of condensed Blutz Waves is created. Using this, a Saiyan can achieve the Great Ape transformation even when a full moon (or similar planetary body) is not present. Attack Pods also come equipped with a device that can project a hologram of a moon that is realistic enough to allow Blutz Waves to be reflected in the event of their landing on a planet that lacks a moon. The highest form of the Great Ape Transformation is known as The Golden Great Ape Transformation but requires a Saiyan to have mastered The Great Ape Transformation and also be able to transform into a Super Saiyan.

After observing the Saiyan instructor demonstrate the Power Ball technique to a group of Saiyan youths a single time Broly suddenly felt that he now understood all of the techniques intricacies. Surprisingly he succeeded with his first attempt, perfectly employing the technique as he created a pale, moonlike orb above his right hand, which he quickly crushed anxious that he may inadvertently trigger The Great Ape Transformation. This effortless success lead him to the wondrous discovery that he now possessed one of the most coveted abilities of the Dragon Ball Multiverse, Mimicry, which is the miraculous ability to copy another fighter's technique after seeing it used only once.

Flying also came easily to him, as he effortlessly moved himself slowly around the inside of his incubator by will alone, his precise Ki Control causing him to barely exert any Ki at all, remaining in a lotus stance as he slowly spun himself around in every direction. After several hours of playfully zigzagging in every direction possible Broly figured he had successfully learned to fly. Further mastery would have to wait for a future point in time after he finally left his incubator for good.

After spending 9 entire months within the latest incubator while continuously training his Ki his infant body had already started its qualitative metamorphosis from that of a newborn infant into that of a young child with some musculature definition. The incubators exterior physique augmentative environment coupled with his interior promotive Ki training had created a perfectly balanced synergistic effect upon his entire body inside and out, continuously strengthening him all the way down to his cells at a measured pace, with each breath he took he could feel himself growing inexorably stronger in every way possible.

Now having finished laying his solid foundation his great future was even more likely to be greater thanks to his diligence, knowledge, and unlimited resources he was already off with an excellent start, and was completely sure he would greatly surpass his martial peers. Having learned several new techniques it was now time to begin mastering one of his most important innate techniques, Powered Shell.

Originally Powered Shell was the first technique ever used by Broly, who had employed it instinctively while and infant as Planet Vegeta was destroyed around him, so by that fact alone he felt confident he would be able to learn the unique Ki Barrier technique with great ease. Alas it wasn't as easily acquired as he thought for he had forgotten to take into consideration the immense amount of pressure Broly had been in with death all around him, his little heart racing as he desperately sought a way to survive forcing all of his potential to suddenly awaken this unique technique to save himself.

However in the end thru sheer diligence he still managed to learn it, for after several days of tireless practice and experimentation a small translucent sphere of greenish energy barely large enough to contained his entire body flickered into existence around him, quivering a few times before fully solidifying. In the weeks that followed this resounding success his continued experimentation coupled with his unique creativity allowed him to further improve the technique to the level where he could not only create multiple Powered Shells simultaneously but could even use Powered Shell independent from his body, enabling him to encapsulate other things around him within a certain albeit limited range.

Unfortunately one of the limitations of this technique was the requirement that the item or person would have to be fully encapsulate otherwise whatever was not within the sphere would be severed when the walls of the sphere were formed, a fact he surprisingly learned when he was practicing with a chair next to his incubator, the incident leaving half a chair with a smooth spherical cut separating the back from the seat looking as though someone had used a massive razor sharp ice cream scoop on it.
