SALUTATIONS!
Yes! The title says it all! And it’s insane!!!
So, recently I just found out that Skadi’s (The corrupting Heart) Inspire works even on Mon3tr!
And so I got curious: if Inspire works on Mon3tr what else could you add to make this Monster even more murderous?
After reading about some Operators and doin some math (not meth!) I stumbled upon some insanely high numbers!
I mean, Mon3tr already is the most powerful creature you could control!
BUT with the help of Aunti Whislash, Skadi Alter and Swire I managed to (theoretically) turn Mon3tr into an insanely Powerful Raid boss!!!
So, allow me to explain how:
(Besides, all those calculations are with the Operators at Max Lv. And maxed out Skills + Trust Bonus and Skadi Alter using her 2nd Skill all the time!)
 Hp:
Mon3tr has 5433 Hp and since Inspire works on her (Yes! Apparently it’s female)
Mon3tr should (theoretically) also get Skadi Alter’s 20% Of Atk constant Hp regeneration! (Skadi Alter’s Skill 2 Activated)
That would make 83,6 Hp per second! This might not sound much but after only 10 seconds this would have regenerated 836 Hp! 10 more seconds and 1672 Hp got healed! In half a Minute 2508 Hp!
It takes Skadi half a Minute to regenerate (almost) 50% of Mon3tr’s 5433 Hp!
 Atk
Mon3tr can reach a base Atk of 1402 Atk! Already the highest Base Atk in the Game!
But this is absolutely nothing compared to what you can amount with a bit of help!
Let’s add Skadi Alter’s Skill 2 (Wish of Burial Beyond the Light):
(At Skadi’s best + Trust Bonus)
1402 Atk + 250,8 Atk = 1652,8 Atk
Now, let’s add Swire’s Talent (Melee Combat Guidance) Atk Bonus: 12% of Atk (12% of 1402 not 1652,8)
1652,8 + 168,24 = 1821,04 Atk
Crazy, right?!? But that’s not all! That would be Mon3tr’s constant Atk stat without activating any temporary Skills!
So, let’s get to it:
First, let’s activate Kal’tsit’s Skill 3 Command: Meltdown (+ 260% of 1402 Atk):
1821,04 + 3645,2 = 5466,24 Atk
(Insert Yugioh Atk Increasing Sound)
This would already be enough to kill Seto Kaiba’s favourite 3 headed Dragon but let’s go and activate the Trap Card “Overkill!”
Or in Arknights case: Swire’s Skill 2: Cooperative Combat
(The Talent is 3 Times as effective, so instead of + 12% Atk we get + 36% Atk):
5466,24 + 336,48 = 5802,72 Atk
Now that is Power!!!
. . .
What? Still not enough?!? Well, why not place Mon3tr on an Active Originium Tile then?
(Not sure how much the Atk increase with those is tho . . . )
Last but not least, let’s look at the . . .
 Defense:
Mon3tr Base: 405 Def
With Skadi Alter’s Skill 2 (60% of Defense):
405 + 157,8 = 562,8 Defense
And now we add Auntie Whislash’s Talent Rebuke (+ 14% Defense):
562,8 + 56,7 = 619,5 Defense
Meh, not too great . . . Let’s change that!
Let’s activate Command: Meltdown again (+ 200% Defense):
619,5 + 810 = 1429,5 Defense
Now that’s more like it! Now we can keep up with the big ones!
But let’s make sure we stay ahead while we are at it:
Activate Auntie’s Skill 1: Motivational Skills (Talent is 3 times as effective, so instead of 14% Defense we get 42% Defense):
1429,5 + 113,4 = 1542,9 Defense!
Now that is hardcore!!! Literally!!!
So, let’s summarize all this:
If we combine Kal’tsit & Mon3tr with Skadi Alter, Whislash and Swire, we get:
A Monstrosity of a Raid Boss with:

5433 Hp and (theoretically) regenerates half of it’s Hp in half a minute!
(And Kal’tsit gives even more extra Heals!) 
5802,72 Atk and True Damage no less!!!

1542,9 Defense!

+8 ASPD (or +24 if Whislash Skill is activated)

Should Mon3tr die despite all this (literally how?!?): Every opponent around Mon3tr gets a 3 Second Stun and 1200 True Dmg

And if that all is not enough: After 25 Seconds everyone’s favourite angry Backbone will be back with a furious Vengeance!!!
Holy hell!!! Can anything actually stop this creature?!?
