Goku

Son Goku, born Kakarot (Kakarotto), is the main protagonist of the Dragon Ball metaseries. Goku is a Saiyan originally sent to destroy Earth as an infant. However, a head injury at an early age alters his memory, ridding him of his initial destructive nature and allowing him to grow up to become one of Earth's greatest defenders. He constantly strives and trains to be the greatest warrior possible, which has kept the Earth and the universe safe from destruction many times. Goku looks almost exactly like his father, Bardock, possessing the same spiky jet black hairstyle, dark-colored eyes, and facial features. However, he has softer eyes, a kind demeanor, and a lighter-pale skin complexion from his mother, Gine. Goku's most distinguishing physical characteristic is his hair. He has three bangs hanging to the right of his forehead and two bangs hanging to the left. His hair also stands up in the front with four spikes and three bangs in the back (later in the anime he has five spikes in the front and four in the back). Goku was born with the signature tail of the Universe 7 Saiyans, which was long and prehensile with brown fur. It was removed and regrown multiple times in his early childhood, but in his late teens, Goku's tail was permanently removed by Kami in order to prevent his Great Ape transformation. Goku is one of the strongest mortal warriors in multiverse, often referred (including deities) to as the most powerful and fittest warrior in Universe 7, as well as a one of the most powerful characters in the franchise. A prodigy of combat, he learned a great deal while a young child and would continue to near-effortlessly learn practically any new technique he encountered. His natural talent for battle along with his unwavering drive have taken his power to unprecedented levels to the point of reaching and rivaling the domain of the Gods of Destruction. Ultimately, Goku's might immeasurable potential has made him believed to be incomparable and even unbeatable for any other fighter when he is at his absolute peak.

As an infant, he could drag large rocks tied to him while pursuing food and resist his adoptive grandpa's attempts to hold him down. When first meeting Bulma, he was unfazed when rundown by her car and shot, quickly picking up and throwing her car with her in it. He defeated a Pteranodon, a pack of wolves and a Bear Thief with ease. When meeting Yamcha, Goku fought on par with the bandit despite being weakened from hunger. Later, as a Great Ape, Goku effortlessly destroyed Emperor Pilaf's castle. While training under Master Roshi, Goku consistently outperformed Krillin and amazed the teacher, including moving large boulders and running a 100-meter dash in 8.5 seconds. Goku and Krillin accomplished various grueling labors a day that outperformed an entire work-force of adults. By the 21st World Martial Arts Tournament, Goku's might could move a massive boulder. In the tournament, he breezed through the preliminaries while holding back significantly and developed various new techniques against his foes. In the finals, Goku fought on par with the seasoned veteran "Jackie Chun" and likewise replicate practically every maneuver his opponent used on him, narrowly losing by lack of stamina after a double count-out. While fighting the Red Ribbon Army, Goku did not experience any serious trouble against the majority of their fighters, with only General Blue providing any meaningful resistance through the use of his telekinetic abilities. In hand-to-hand combat, however, Goku still managed to handily come out on top after a short but intense struggle. During this time, Goku had also fought on par with the Pirate Robot, an ancient but powerful fighting machine, before finally defeating it with an aeriel assault.  When facing Mercenary Tao, Goku was toyed with by the deadly assassin and only managed to mildly hurt the foe with his Kamehameha before being defeated himself. After training with Korin, Goku defeated Mercenary Tao with ease, able to block Tao's Dodon Ray with only mild pain. Goku then proceeded to single-handedly destroy the entire Red Ribbon Army's headquarters and defeat all of its soldiers. Even Staff Officer Black's Battle Jacket was beaten easily.

To get help from Fortuneteller Baba, Goku faced and defeated her supernatural foes including Bandages the Mummy and Spike the Devil Man with mild effort. He then fought on par with the resurrected Grandpa Gohan, who resorted to grabbing Goku's tail to get an advantage. During the 22nd World Martial Arts tournament, Goku defeated a former champion in King Chappa in the preliminaries. He gradually overwhelmed Krillin, even taking Krillin's Kamehameha with a single hand. As Krillin attempted to stop Goku by grabbing his tail, Goku is revealed to have trained it to be as strong as the rest of his body. Goku then defeated Krillin too fast for anyone but Tien to see. Against Tien in the finals, Goku proved able to counter virtually everything Tien used on him, forcing him to instead rely on a count-out by destroying the ring while he flew. Against Tambourine, Goku was bested due to his exhaustion and hunger after the aforementioned tournament. Once he regained his strength, however, Goku easily defeated and killed the monster. Almost immediately after, Goku was confronted by the weakened, aged King Piccolo himself and dominated at first due to taking him by surprise. However, once King Piccolo got serious, he soundly defeated Goku and easily withstood his Kamehameha. After drinking the Ultra Divine Water, Goku's potential was unlocked, enabling him to easily defeat Drum, King Piccolo's most powerful warrior who had effortlessly beaten Tien, and fight on par with King Piccolo himself, who was restored to his prime and eventually defeated him. After training under Mr. Popo for three years, Goku's all-around performance increased remarkably to surpass his teachers. In the 23rd World Martial Arts Tournament, with weighted clothes, he effortlessly made it to the semi-finals. Once removing his weighted clothes, Goku's speed proved too great for Tien to even perceive and quickly defeated Tien. In the finals, Goku noticeably outfights King Piccolo's stronger reincarnation, Piccolo Junior, gradually wearing down the foe to ultimately defeat him and become acknowledged as the strongest in the world. While Goku's might was extraordinary by human standards, it was revealed that by even Low-level Saiyan standards, Goku's power was considered extremely pitiful. This is evidenced by how he was outclassed by his older brother Raditz, considered a mid-class warrior himself. Despite aid from Piccolo, he only managed to defeat Raditz by dying with his brother while holding him and also taking Piccolo's blast. After training with King Kai, Goku easily defeated Nappa, the Commander-in-Chief of the entire Saiyan Army, and fought on par with Vegeta, a Super Elite warrior, although he needed to use Kaio-Ken x3 in order to overpower the Saiyan prince. After healing from his fight with Great Ape Vegeta and training at x100 Earth's gravity, Goku's power far exceeded Saiyan standards, easily defeating Ginyu Force members Recoome and Burter, the former of whom pummeled Vegeta and Gohan, and fight on par with Captain Ginyu himself. After healing from his Body Change experience, Goku's power increased immensely, and through various tactics and newfound strategies, forced the powerful tyrant Frieza to fight seriously at 50% of his true power. Only when he used Kaio-ken x20, could Goku land an attack on Frieza at 50% power, and even then, his attack failed to give Frieza any major damage. After transforming into a Super Saiyan, Goku completely outmatched Frieza at 100% power, calmly dominating the foe once fighting seriously.
