Identical case-stating arguments X2 (well, in all honesty, this is my teams' kind of round - it's the kind of thing I had in mind when I made these teams)...
Obadiah Horn Team 1
James Bond (Pierce Brosnan)
The Bride (Kill Bill)
Indiana Jones (Temple of Doom)
Zhuge Liang (Red Cliff)
Jason Bourne (The Bourne Ultimatum)
KJ Stewart Team 2
The Master (Whoniverse)
Emil Blonsky (MCU)
Victor Von Doom (Fantastic Four Movies)
Red Skull (MCU)
The Master, Doom, Ozymandias and Red Skull definitely get through by virtue of being intelligent, tactical, deductive geniuses. Blonsky is the only "maybe", but by virtue of being a military leader (a leader of special ops tactical teams put in charge of pursuing the classified Hulk case, nonetheless), he's not exactly stupid.
That said, we'll assume nobody buys him getting through and stick with the genius quartet of the Master, Doom, Ozymandias and Red Skull.
We have prep. With the Master... with Doom.... with Ozymandias... and Red Skull.
The Master rivals the Doctor for prep - enough said. This version of Doom was the one who discovered what the source of the Silver Surfer's power was and was entrusted with studying the Surfer's board (which he understood) and was the one who designed the Tachyon pulse device that separated the Surfer from his board. Ozymandias designed the Intrinsic Field Subtracter that broke Doctor Manhattan in to atoms. And Red Skull is the mastermind who planned to overthrow Hitler after masterminding a scheme to gain a key place in his army, the man who could see beyond appearances and managed to see the truth behind myths believed to be superstition, in reality fragments of Asgardian origin, and the man who had the technological know-how to know he could make weapons with the Tesseract.
Hell, the Master with prep could DESTROY the other team on his own. He could turn the cube into drones of his own and make them in to absolute monsters, for example. No one comes close to him on the other team. With three other geniuses alongside him - two of whom (Red Skull, Ozymandias) are also very capable fighters, if it comes down to it - should defeat them with utter ease. The cube could be turned in to machines that smash people in to atoms, for example.
And that's without Blonsky who, frankly, could probably make it to the final fight as well (but really isn't needed).
KJ Stewart Team 1
The Doctor (Whoniverse)
Reed Richards (Fantastic Four Movies)
Wesley Wyndham-Pryce (Buffyverse)
Captain America (MCU)
Moonknight11 Team 1
Khan (Star Trek: Into Darkness)
Malcolm Merlyn (Arrow)
James Bond (Connery)
Richard Harrow (Boardwalk Empire Season 3 Finale)
The Doctor, Reed Richards, Batman and Wesley Wyndham-Pryce definitely get through by virtue of being extremely intelligent and deductive. Captain America is the only "maybe", but by virtue of being a leader of men who devises precise military tactics that helped to defeat an alien race and, in his first movie, saved the entire Eastern seaboard, he's not exactly stupid.
That said, we'll assume nobody buys him getting through and stick with the genius quartet of the Doctor, Reed, Batman and Wesley.
We have prep. With the Doctor... with Reed Richards... with Batman.... and Wesley Wyndham-Pryce.
THIS Doctor was capable of hacking in to an alien spaceship using a god-damn iPhone. Imagine what he can do here. Reed Richards created flying transport, weaponry, tracking devices and monitoring devices etc. Batman brings stealth, tactical genius, weapon creation and usage expertise. Wesley Wyndham-Pryce could bring the magic mojo.
Hell, the Doctor with prep could DESTROY the other team on his own. The guy constantly turned tech against people (hell, THIS Doctor turned a Spoonhead version of himself in to something that acted and spoke like him in a few moments. It could even ride a frigging motorbike - imagine what he can do with the cube). With Batman, Wes and Reed backing him up (two of whom are capable fighters in their own right), this should be an easy, easy, easy victory.
And that's without Cap who, frankly, could probably make it to the final fight as well (but really isn't needed).
