It’s gotta be Boom Bewm, almost everyone who owns the game has beaten them and loads of people farm them for XP until lvl9/ 10

I think a boss worth mentioning is graveward from bl3. I think the fact that it's a must kill boss + good legendary farm for a significant portion of the games life cycle + super accessible for bl3 players to farm in that game compared to other stuff made it die a lot. The amount of world drops, the build benchmark aspect, and easy save quit for a relatively longer save quit game compared to 2 and bl4 are also decent reasons imo.

"Which Borderlands Boss Has Died the Most"

In my head I’d say most farmed is Savage Lee, but most killed could be Knuckle Dragger, especially considering multiple playthroughs per character.

Crawmerax bl1 probably just due to the amount of time it’s been available. Some players still farm him daily for the pearls

2nd might be hunter hellquist for the bee shield - until farming the treats in the tiny Tina dlc made it easier to get a bee. Those aren’t bosses but I wouldn’t be surprised if they have been killed the most.

I feel like Boom Bewm has to be up there with Knuckledragger for two reasons.

1: You don't have to kill Knuckledragger in UVHM, but you do have to kill Boom Bewm in it. So people who aren't farming for meta items or don't complete UVHM or want to reach the OP levels, they could have killed Boom Bewm without killing Knuckledragger.

2: Whenever I do a semi-casual run in BL2, I usually reach Level 5 right before or when I kill Boom Bewm depending on if I got to level 3 from opening the door at Digistruct Peak. And because you used the achievement for reaching level 5 for your calculations, it could also mean that Boom Bewm has been killed a similar amount of times as Knuckledragger.

Splashzone. Hes the first boss who introduces the encore mechanic, and is piss easy to get to.

I wanna say savage lee, hunter hellquest or  the bunker. The bee and savage lee are often farmed for some of the strongest loot in the game. The bunker because there is always a hunt to get a perfect sham.

Bunker for all of the shams.

my guess is between splash zone, bewm boom, and like.. savage lee.. if that counts as a boss

pre-watch guess: savage lee if that counts as a boss, if not then bunker (due to the sheer amount of people trying to farm for a perfect sham and how rare it is)
that said in a couple of years it'll more than likely be splashzone

The Bunker in BL2, because Zero could insta kill it, and farming up a perfect roll Sham shields for norfleeting.
I think Savage Lee was not it, as it felt way easier to farm the torgue vending machine in the Torgue DLC.

I feel like crawmerax had a good run just because he was there the longest and one of the few farmable bosses.

Buuut I think bl2 is more likely to have the most killed boss. I m going to go with badmaw because you farm him for exp early in speed runs and if you fail a run it'll probably be after the badmaw farm

Depending on how the 4 Kings count, they could be up there. Anybody who gets the Grog Nozzle, anybody who beats Dragons Keep. If all 4 kings count as 1 kill, then eh, especially since it's dlc. But still.

It’s def Midge Mong mhmm mhmm

(Haven't finished the video) My thoughts would be Hunter Hellquist. The Bee is the most meta-defining shield in the most popular game in the franchise. He's a very short drive away from the area spawn point and in a section of the game (in between Control Core Angel and The Warrior) where you'd prefer grinding bosses for XP rather than doing sidequests, making him a really easy farm.

My last run on Badmaw for lvl 55 to lvl 80 was 1160 kills.

Could be BL1 Craw with all the people farming pearls

GBX has all this info. Maybe one day they will come out with it & prove you right.

Crawmerax 100%
