[Indestructible Saiyan Evil] LSS Broly is the uncontested king of the World Tournament in Dokkan Battle, the strongest AoE unit in the game ever since his introduction. One of the hardest hitters in Dokkan that partially sacrifices his DEF in order to perform so well offensively.
On this team LSS Broly is again one of the main hitters. LSS Broly does not synergize particularly well with the rest of the team and should be put on rotation with Goku Black (SSR) to Super Attack consistently.
"Resurrected Warriors" is a strong team, but it has poor synergy. LSS Broly should be put on rotation with Hideous Super Saiyan Super Saiyan Broly, his TUR version, to perform at his best: these two units together are going to deal a lot of damage, but also take a good amount in return since both of them lower their DEF when launching the Super Attack.
LSS Broly's 12-17 ki and 18 Ki Super attack are pretty standard, no additional effect, colossal and mega-colossal damage respectively.
LSS Broly is the 90% leader for STR types.
When performing a Super Attack, LSS Broly gets 80,000 ATK and loses 20,000 DEF. This used to make a glass cannon, but in the current meta, under the double True Radiance of the Emperor Golden Frieza (Angel)'s +170% DEF Leader Skill for example, it only equates to a little over -40%. As the times goes on, the DEF debuff becomes less significant, but the ATK boost will suffer as well. Fortunately enough the loss in DEF happens only after the Super Attack, meaning that LSS Broly is going to keep his LR DEF up to that point. The part that really makes this unit so strong is the fact that LSS launches an additional Super Attack automatically, a free 12 Ki Super that significantly increases his damage output for the turn.
LSS Broly has "Fierce Battle" and "Super Saiyan" as relevant ATK links and "Prepared for Battle" as his main Ki links. Since most of the times this unit is paired with Hideous Super Saiyan Super Saiyan Broly, his TUR version that does not share the same name, most of his links, excluding "Legendary Power", are going to be active consistently.
As I said quite a few times, this is LSS Broly's best partner on rotation in terms of links, adding 3 Ki, 25-45% and 700 flat more ATK to each other. Both of them are glass cannons and are to be used carefully in the most recent events.
Goku Black (SSR) is an amazing partner for LSS Broly, he provides him 3 Ki with his Passive, 2 Ki with "Prepared for Battle", 25% ATK through links and a 50% DEF boost. The last part can partially fix LSS Broly's DEF, stacking a higher percentage boost in exchange for the minor DEF debuff can make him slightly above average when it comes to taking a hit.
Maximizing Criticals is always the best way to go, but because of the how LSS Broly's Super Attack works a investment in Additionals is not a bad idea. If LSS Broly gets an additional Super Attack he will perform one more after that thanks to his Passive. Dodges can be beneficial, but, as I said, as the time goes on, LSS Broly's defensive liability is going to become less important.
LSS Broly is completely farmable up to SA 10 through Lurking Fear Broly. The real investment with this unit are not the 10 Kais to bring him to SA 20, it's the cost in zenie to fully awaken him and the amount of medals needed.
