Aqua Ring Substitute Shell Smash Baton Pass

Pangoro Mold Breaker Adamant 252 ATK 252 SPEED Sash (all bosses) Lum Berry (Thor, Surge)
Power Trip, Crunch, Earthquake, Storm Throw
Note: If your Pangoro is Mold Breaker but not adamant, not +atk or shit ivs
You will need to Shell Smash 3 times which leads to the Boss having more chances
To win against you. PLEASE USE ADAMANT, 20+ IV ATK AND SPEED. PLEASE.
Don't use anything worse. This guide assumes you Shell Smash only 2 times per boss
unless indicated.

FOR ALL BOSSES:
NEVER BATON PASS UNTIL YOU ARE BEHIND A SUBSTITUTE. SOME BOSSES HAVE PRIORITY ON SOME
POKEMON AND YOU WILL DIE HALFWAY THROUGH THE SWEEP.
ONLY BATON PASS WITHOUT A SUBSTITUTE IF YOU HAVE 2 SHELL SMASHES (OR 3) AND ARE DESPERATE
AQUA RING HAS TO BE USED WHEN BELOW 50% HP IN CASE YOU GET REALLY BAD RNG

FIGHTING/DARK TYPES CAN SURVIVE 1 POWER TRIP FROM 2 SHELL SMASHES, BUT NOT FROM 3
XERNEAS, MEGA TYRANITAR CAN ALSO SURVIVE 1 POWER TRIP WITH 2 SHELL SMASHES
^very VERY LOW CHANCE. like 1 in 10  times.

The damage calculations with shitty Pangoros are confusing.
PLEASE USE ADAMANT 25+ ATK IV MOLD BREAKER (or Naughty/Lonely).
DON'T USE A SHITTY ONE. Try 10+ IV SPEED too.

DON'T FORGET STEALTH ROCKS!!!!!!! Some bosses are REALLY ANNOYING or you might autolose
if I wrote Stealth Rock in a boss IT MEANS IT'S OBLIGATORY.
One of the pokemon might have a focus sash or be able to survive a hit from Power Trip.

BE CAREFUL ABOUT PRIORITY MOVES.
ARCEUS LUCARIO ENTEI ARCANINE SOMETIMES USE EXTREMESPEED. THIS MOVE HAS 5 PP.
These are the only Priority Moves I've seen being used in Bosses.
I only highlight these because these are in LEAD Pokemon.

IF AN OPPONENT HAS -6 ACCURACY YOU DON'T NEED TO SWITCH AROUND BETWEEN YOUR POKEMON.
GET ROCKS IF NEEDED, THEN USE MAGNEZONE'S TWAVE AND EXPLODE TO SAFELY SWITCH IN GOREBYSS.
EVEN THOUGH SKARMORY IS NORMALLY ONLY NEEDED FOR STEALTH ROCKS, IF YOU WANT TO
YOU CAN SKARMORY FLASH FIRST, THEN MAGNEZONE FLASH + TWAVE + EXPLODE.
THIS ALLOWS YOU TO GUARANTEE A SAFE SWITCH BY EXPLODING WITH MAGNEZONE WHEN YOU'VE
ENSURED THE OPPONENT'S ACCURACY IS AT -6

FOLLOW MY INSTRUCTIONS EXACTLY.

List of Bosses I do and the ones I recommend adding / swapping

Kanto & Johto Part 1

Xylos (complicated a bit) - REQUIRES ALL EEVEEOLUTION CAUGHT DATA
Start with Whimsicott and switcheroo the Tail onto Xylos while it kills you
Golduck Simple Beam - Flash as much as you can before it faints

Start Golduck Simple Beam - Flash until you die or -6 accuracy
Whimsicott Cotton Spore - Flash until you die or -6 accuracy

Jenny (complicated) - REQUIRES PINKAN ISLAND QUEST
Start Golduck Simple Beam - Flash until you die
Switch to Whimsicott - Flash until -6 accuracy, THEN Switcheroo, then Memento

Ash Westbrook (OPTIONAL) - The hardest boss for Bpass in the game, 250 hours playtime
Start Skarmory and Whirlwind. 97 things can happen here:
If Dialga Roared you, since he has a higher base speed and both moves have the same priority,
Skarmory will always be kicked out. If he does this, you cry inside. You basically will have
to sacrifice a pokemon to safely switch back to Skarmory.
If you managed to Whirlwind successfuly:
If Reshiram comes in: HASHAWHASHASDHASDHASDHASDASHDASHDASHDASH I AM GOING INSANE THIS DUDE HAS
ROAR TOO HAHAHAHAH i want to DIE, repeat the same process
If Arceus comes in: This dude has Extremespeed, Life Orb (which means it will die after 10
successful attacks) and Multitype. This ability currently is bugged and does not let you use
Simple Beam (it's immune) or Switcheroo (you cannot remove the item). Try to Whirlwind this
out. Otherwise try to Flash + Thunder Wave this and set up
If you get Lugia, Kyogre or Infernape: Switcheroo the Tail, Simple Beam, Debuff, setup and sweep!
