Kaido Profile
Age: 59
Birth Date: May 1st
Gender: Male
Height: 710 cm (23'3½" ft)
Professional Status: Yonko (Four Emperors) /Captain of the Beast Pirates
Address: Wano Country (Onigashima)

The Governor-General of the Beasts Pirates and one of the Four Emperors that reign over the New World, Kaido of the Beasts is known as the "Strongest Creature" in the entire world. Formerly a
promising young soldier in the Vodka Kingdom's army, Kaido was recruited into the Marines against his will but managed to escape and begin a career in piracy. He accepted Edward
Newgate's (WhiteBeard) request to become an apprentice and joined the legendary Rocks Pirates,

where he met and befriended Charlotte Linlin. During the God Valley Incident, which resulted in the defeat of the Rocks Pirates, Linlin presented Kaido a rare Mythical Zoan fruit called the Uo Uo no Mi, Model: Seiryu (Fish-Fish Fruit, Model Azure Dragon).
Then he put together his own crew, growing it into a fearsome military force dedicated to opposing the World Government.
Kaido joined forces with Wano Country's shogun, Kurozumi Orochi, and established Onigashima as his stronghold after receiving an invitation to the country from Kurozumi Higurashi. He proceeded to build up his military strength in Wano Country after Kozuki Oden and the Nine Red Scabbards' unsuccessful effort to overthrow him for 20 years before choosing to get rid of Orochi and move through with his New Onigashima Project plan.

Monkey D. Garp first made reference to Kaido in the Post-Enies Lobby Arc when he revealed the existence of the Four Emperors. Gecko Moria then made the first direct mention of Kaido in the Thriller Bark Arc, and after the Straw Hat Pirates defeated Moria, his status as one of the Four Emperors was made known. Kaido is the final Emperor to make his debut and the third Emperor named by name. Kozuki Momonosuke initially heard him in a flashback when getting off the ship on Dressrosa, before making his public appearance. He serves as both the main antagonist and one of the main villains of the Wano Country Saga.

Broly (The Legendary Super Saiyan)
Broly Profile
Age: 48
Birth Date: Age 732
Gender: Male
Height: 300 cm (9'10" ft)
Professional Status: Allegiance Frieza Force (formerly)
Address: Vampa

With a 10,000 power level at birth, Broly was Prince Vegeta IV's contemporaries in age 732. He was transported to a frontier world by a jealous and paranoid King Vegeta III, who denied the possibility that Broly was more talented than his son, Prince Vegeta. He had resided on Planet Vegeta until that point. Upon Broly’s exile to Vampa, Broly's father Paragus managed to steal a ship to go after and protect his son. Coincidentally Broly’s exile and his father's escape effectively ended up saving them from the destruction of planet Vegata at the hands of Frieza.

There was also a suggestion that Broly visited Great Ape soon after landing on the planet since he had seen its moon when he had awoken from the landing. He met a huge beast that he named Ba when he was on the planet. Broly would frequently engage in combat with Ba, deflecting its blows, until they eventually became friends as a result of their many interactions. Unfortunately, Paragus (Broly's father) shot the creature, severing its ear in the process, because he considered this development as damaging and impeding Broly's progress. After this incident, Ba left and never trusted Broly again. As a reminder that he would always be with Ba, he would wear the severed ear as a green pelt (akin to a sash). Broly serves as both the main protagonist and misguided central antagonist of the movie, Dragon Ball Super: Broly.
Speed: Immeasurable- Massively Faster than Light
Speed
Kept up with Super Saiyan Goku and Vegeta, and eventually became able to keep up with the former's Super Saiyan God form
Forcing Goku into utilizing Super Saiyan Blue and evolving to that level as well. In his Full Power Super Saiyan form
He somewhat kept up with Super Saiyan Blue Gogeta
Strength: 'IT'A OVER 1,400,000,000!!!"
Strength
Broly was born with a power level of 10,000 which continued to grow as he trained with his father
Beserk mode: His power continues to increase as his rage grows
Durability: Extremely High
Durability
Consistently portrayed as capable of fighting for long periods of time, rarely being shown to get tired
Fought Vegeta, Goku, Frieza and Gogeta (Goku x Vegeta Fusion) in one afternoon
IQ: Primitive-Mind/Adaptive Battle style
IQ
As he spent most of his life stranded on Planet Vampa, with only his father to interact with for the most part, Broly's general intellect is hardly worth noting.
Despite his limited intelligence, he still manages to be a rather capable fighter whom can adapt and learn in the midst of battle
Weakness: Temper
Weakness
Broly can be easily manipulated due to his ignorance of society and how beings interact
Beserk mode: His rage can consume him triggering his power to self destruct unless he releases it in battle
Verdict: This is fight is incredibly difficult to determine who would win, not only for the sheer difference in verse powers (Ki vs Haki+ Devil Fruits) but also the level of strengths these two posses seem to be ever-growing the more they battle. While Broly's raw strength and adaptive fighting style allows him to keep up with virtually any enemy, Kaido posses an insane resume of battle feats and experience. Kaido's temperate would lead to his success in this fight. While extremally dangerous and power, Broly's berserk state can also harm himself and result in his power to self destruct. Due to Broly's inability to control his emotions and power our Verdict is that Kaido wins this intense and definitely lengthy battle.
Winner: Kaido ("In a one v one.., bet on Kaido")
