pretty silly situation

Oh no
Well uh let's see
If Mr knew he was brainwashed, most likely, yes. Most times he loses fights is when he doesn't want to hurt someone too badly. If he were teamed up with his brother he would almost certainly win

What if TRK got the drop on them

Like a Predator section from the Batman games

Well uh then that's what the brother's for
Worst case scenario, they come back after dying and beat him

TRK also has a serum he's been making

It makes people hallucinate, and makes them more emotionally sensitive

Perfect for making people terrified

Serum + Anger + Adrenaline + Sharp Mindedness = STRONGER

How

Anger - Stems from being mad that he has to fight Raven and that his friends are in danger, driving him to fight, producing Adrenaline
Adrenaline - Makes Mr a stronger and better fighter
Sharp Mindedness - Being stronger against hallucinatory imagery and or sound

TRK could also make him even angrier and reckless by saying such things such as

"Once I'm done with you two, the kid is next...then the spider. So don't bother coming back.."

Oh Mr would put him through 2.5 walls if he said that

Can't hit what you can't see

Well think about it
If he can't see very well
That means his other senses (such as hearing) are heightened
Also if you threaten any of his friends and plan to deliver he will KILL YOU

Anger also makes you think foolishly

oh wait till you hear about willstrength, a psychological phenomenon in the minds of every Rotisserieverse character

Wait isn't that how a normal human works sorta
Adrenaline??!

kinda
except if you get pumped up on too much willstrength you will become a cosmic horror

But is he resistant to gun

who said he's using a gun

Smoke bomb:

literally wouldn't affect willstrengthened Lian

Whomst

basically the more pissed of somebody is, the more of a threat they are to whatever pissed them off

Sharp Mindedness also makes you calm and collected
Or at least, more so

A raven standing on the floor:

Immediately causes him to speedily search the room

He is in the shadows

Mr, knowing that his mind has been controlled, quickly restrains his arms and legs with large, strong faceappendages that were hidden previously

The Raven King tests out his theory about freezing Mr's face with liquid nitrogen.

How would he do that if he can't use his limbs

His ravens could do a silly little airdrop

Mr would spin some wide facespikes at a speed so great, that the ravens were simply flung away, with the Liquid Nitrogen (which would probably be very hard for the ravens to handle anyway). Meanwhile, Sir, out of nowhere, began restricting Raven's breath by wrapping a tight faceappendage around his neck, as well as absolutely pummeling him with facearms

He struggles through his breath. "C....Cycle.....C.......C...Call...."

Mr was confused at this and Sir takes this as a threat, so he tightened his grip and started punching his head and face more. Mr immediately becomes defensive and quickly dashes about the whole area to check it

"...He's too powerful...I couldn't beat him.."

Mr: "... that's fine...
... sorry about having to... Y'know.."

"It's alright.."

Sir: "I think I messed up your suit a bit."
*He picked up one of the blades he removed from the suit and Mr lowered the dome a bit*

"Did you hurt my birds?"

Mr: "No. We made sure not to."
Sir: "We just blew em away"

He stared.

Mr: "..like this, but bigger."
*He stuck out some fan blades from his neck and spun them*

"Hm."

"They're fine. I know you like your birds. Besides, it would be pretty hard to fight them any other way."

His motorcycle quickly drove in on its own, and a flashbang slid out of one of its compartments.

Mr threw himself towards it, absorbing most of the light and sound that came off of it
Sir pretty much ties up Raven with faceappendages and starts attacking with larger, brawnier arms

A few blades pop out of the arms on his suit, cutting into his appendages.

"OW SH**"
He forces in much smaller appendages into the suit, which break and remove the blades
He goes deeper, which starts to cut him

Suddenly, a massive horde of ravens fly over, violently attacking both of them.

He spins around extremely quickly while taking on a shape similar to a turbine, repelling the bird as well as completely disorienting Raven
Mr has recovered from the flashbang by now and made a dome around everyone. This was extremely hard, more so than bone.

"W-Wait....It's me...."

Mr: "there's no way for us to be able to trust you. Even if we asked you a question only you'd know."

"I....I made a device....to help me break through the mind control...if I was ever captured...that sound like me....?"

Mr: "....
..Sir, stop beating him up."
Sir stopped. Mr left the dome up just in case
