There are several bosses to defeat in the souls-like Lies Of P. If you are having trouble finding and beating them, this Lies of P guide lists every single boss, both major and minor, in the game. We have also included a video that shows how you can defeat them.
Parade Master
The first boss is a giant puppet that has a two phase battle.
Mad Donkey
Relatively ordinary second boss armed with a large cleaver.
Scrapped Watchman
The third boss looks like an old school British bobby or policeman, and runs in two phases.
Survivor
Similar to Mad Donkey, but much more agile.
Puppet of the Future
Another gigantic puppet, armed with a wrecking ball.
King’s Flame, Fuoco
Large puppet with a furnace, hammer, and hand cannon. Two phase battle.
The Atoned
Even more agile than the Survivor, The Atoned can actually be skipped entirely by gesturing with Stalker’s Promise.
Eldest of the Black Rabbit Brotherhood
A three phase fight against four opponents, but thankfully not all at once.
White Lady
A lot speedier than previous bosses.
Mad Clown Puppet
Huge fat clown accompanied by puppets with flamethrowers and grenades.
King of Puppets
Massive puppet with armor and huge arms.
Romeo, King of Puppets
Defeating the King of Puppets will cause Romeo, the true King of Puppets, to emerge, armed with a scythe.
Champion Victor
Huge humanoid creature that runs in two phases.
Owl Doctor
Fast and agile like Mad Donkey.
Green Monster of the Swamp
Arachnid creature with a myriad of moves.
Puppet-Devouring Green Monster
Green Monster of the Swamp will subsume a puppet and completely change its moveset from before.
Robber Weasel
In the vein of previous regular-sized bosses, this one is just as quick and lithe.
Walker of Illusions
Another speedy boss, but this one summons a clone as well.
Corrupted Parade Master
The first boss with a new set of moves, the ability to cause Decay, and spawn an add.
Youngest, Battle Maniac, Eccentric, and Eldest of the Black Rabbit Brotherhood
The remainder of the Brotherhood will challenge you. No longer a fair fight, with two jumping in at once, while the third one waits on the sidelines. When you are down to the last one, the Eldest will resurrect and join the battle.
Door Guardian
A return to giant bosses, this one is armed with a club.
Black Cat
A normal-sized boss that can be skipped entirely with a bribe of a piece of Gold Coin Fruit.
Laxasia the Complete
Huge, fully armored electrical boss with two phases.
Red Fox
A counterpart to Robber Weasel, and just as quick and agile.
Nameless Puppet
You will only encounter this boss based on a choice you make at the end of the game. Two phase battle.
Those are all the major and minor bosses in the souls-like Lies Of P.
