Just wanted to make a quick thing how zenkai boosts work in DBAS (as well as what i personally think the lssj/berserker form is and why only certain saiyans *Broly and Kale namely* only have the form and why its so superior to the regular ssj forms. Again, this is just my thoughts/opinions and moreso how i understood it for my story. If you have a different idea, great! Bt this is just for my story soo yeah.

Zenkai Boosts: 

Zenkai is the ability that allows a Saiyan to drastically increase their power after they recover from near fatal injuries. How i thought it worked was if a saiyan survived from stronger than them the zenkai adds the fldifference between them to their power. Making them stronger. 

E.G:

saiyan a saiyans power is 100. And the opponent has a PL of 200. The 100 loses, gets healed. Zenkai adds the difference (aka the extra 100 from the 200 guy, making his power around 300) and so on. 

Again, thats how i interpreted it based on how vegeta explained it in the manga: E93af0df-19af-4a00-84a8-c195870ffb02 by InstaQuarius

LSSJ/Berserker form:

I like to think of this form as a mutation that occurs with the S-cells in a saiyan. That occurs once every 1k years. (As said by Caulifla in the manga, and apparently the form can even kill them which is interesting.) And only in the sort of oddball saiyans (kale and broly as, unlike more saiyans who are very aggressive and so on. Both appear extremely timid and shy in their base form.) *also yes i know Gine is also a bit odd, tho i think shes just kindhearted- not really timid or anything* 

LSSJ/ Berserker Multiplier:

How i sorta (powerscale) this form compared to the original/regular ssj form is, an lssj/berserkers power is basically equivalent to that of 2 ssj forms higher than regular (Note: i came up with this idea based on Brolys 3 original movies in Z tho mainly the very FIRST movie, since thats when Brolys power was st its peak in the day, and i think probably why broly fans became his favorite to this day. I mean the Legendary Super Saiyan movie was most certainly my main reason why i love the character. Not for the backstory tho (which definitely sucked) but i just loved how much of a beadt he was,  trashing theu everybody like nothing but anyways)

e.g

ssj vs LSSJ (basically equivalent to a ssj fighting an ssj3) and so on.

however, ever since the debut of Kale now im not entirely too sure where Berserker stands in my PL (plus the trailer from Brolys new movie, since we SEE Broly basically trashing Frieza (4th form) Vegeta (ssj) and Goku (SSB) in his base. (And we know Kale in Berserker pretty much trashed a SSB Goku, tho he was exhausted i think but still-)

I think maybe Berserker is even more stronger than lssj? Im not sure- 

like- Berserker might be equivalent to an SSJ God. (Tho then again, the anime also stated i think U6 saiyans are just better than U7 saiyans, since thry evolved differently. And you could stock up why the girls were so easily able to get ssj and ssj2 and stuff because they evolved differently)

i mean, we also see SSJ 2 Caulifla be able to sorta go toe to toe with ssj3 and ssjGod Goku- tho he coulda also been holding back but i mean-

so i still think Berserker is the same as how i powerscaled LSSJ (but because its U6 its more) but anyways

ssj vs Berserker = basically an ssj3 or higher
