It was Su Ming and his symbiote, 'Strangulation'.
Before he experienced the suicidal attack at Concorde Square, he had an inkling of something, and Cable's words prompted him to speculate about the possibility of the enemy being a transmigrator.
Since Deadpool's buddies and girlfriend group were able to come to this era, and the Ancient One never stopped anyone from traveling through time.
So is it possible that... the enemy came this way too?
If the opponent is from the future, it explains the current situation well. They have a guide in hand, and naturally, they can see everything clearly. The strength of the German Army also has a reason.
Because he himself originally wanted to climb the technology ladder.
Luckily, he came from next door, and the 'Marvel Guidebook' in the enemy's hand doesn't contain his story...
He disguised himself as Captain America to deal with Red Skull and Zemo, leading to Zemo's early death, which must have caught the enemy off guard.
This constitutes a 'time divergence point'.
Acting as if he hadn't discovered anything, in order to achieve a greater goal in the future, the enemy will inevitably come to make amends, trying to make the world align with the original history. They might perform tasks like resurrecting Zemo or introducing the second-generation Zemo early.
At the time divergence point, choosing to let the story develop in a familiar direction is what transmigrators love to do, and it's an innate habit.
Because that's what everyone knows as 'history', people like to believe in things they are familiar with, that's human nature...
Time is the same.
Just change a little at crucial time nodes, and the world will automatically help you drive things forward.
And as for insignificant time nodes, it's best not to touch them, as it will only increase the likelihood of unfavorable results geometrically.
For instance, someone travels to the past and gives his young grandfather a light brain, then returns to the future, only to find himself becoming a super second-generation rich or part of a tech family.
But if that person meddles at the time, giving the grandfather a light brain and then killing the handsome old Wang, the neighboring resident, he might return to the future only to find he doesn't exist anymore, wiped out by a time paradox...
Regarding the actions the hypothetical enemy might take, Su Ming also used time theory to set traps, betting whether the opponent would come to clean up the mess.
When he seemingly left the square, he was actually just around the corner, using 'Strangulation' to hide himself, waiting in ambush at the spot where Zemo died, waiting for the hypothetical enemy's appearance.
Perhaps it was Red Skull? The bomb was arranged by him; he should be hiding nearby watching the fireworks, right?
However, it was not. Red Skull survived for so long not because of his strong abilities but because he was more cunning than a fox, more cowardly than a dog.
After detonating the bomb, he merely saw the three being engulfed by the blue light and black mist from afar and promptly withdrew without the intent to check.
Red Skull even took away his men who had blocked the street, pretending as if nothing had happened...
Su Ming slowed his breathing, quietly waiting in the dark alley, he had great patience.
He waited and eventually saw a Hydra Leader he'd never seen before, instantly realizing he had caught the opponent's tail.
He stealthily followed this Hydra, watching him pick up Zemo's weapon and badge, handing them over to Zemo's son, prompting the second-generation Zemo's emergence.
Su Ming instantly locked onto his target.
He assessed this person, discovering along the way, Blue Gloves subconsciously doesn't want to see fire or smell thick smoke, a trait Su Ming used, setting selective fires at intersections after the opponent left Zemo's home, accurately driving the enemy into the trap.
Blue Gloves didn't walk here unconsciously; all his actions were orchestrated by Deathstroke...
"Strangulate them."
Such a thought surged in Su Ming's mind, and the symbiote suddenly sprang up from the ground, like a Venus flytrap, enveloping Heine's squad from bottom to top.
Within, sharp barbs and saw-teeth formed, dealing with Heine's guards inside the dark giant cocoons.
With forceful squeezing, these men were punctured and silenced in the sealed black cocoon.
But Heine still had reaction speed, rolling out of the trap as Strangulation launched its surprise attack.
However, from behind a nearby trash bin, Deathstroke suddenly leaped out, aiming a golden Great Sword at his head with a slash.
Heine's blue hands transformed, like clay, into two energy beams, actually possessing repulsive properties akin to a Light Saber, firmly blocking Su Ming's slash.
Mind you, Su Ming's jump slash carried immense power, cracking the ground beneath Heine's feet, yet he didn't bend his knees even slightly.
"Force? Immortal? Transmigrator? Thanks?"
Su Ming uttered a term with each blade swing, while Heine merely silently fended off the attacks.
Su Ming asked not to distract the enemy but to speculate about the enemy's capabilities.
The opponent's means of resistance should be scientific, not divine power or magic.
Despite his ordinary-looking body, he wielded strength rivaling that of modified people plus symbiotes.
While Su Ming spoke, Heine's expression, gaze, heartbeat, and endurance remained unchanged, meaning he had no emotions.
Combining this information, Su Ming narrowed down the range of suspects, realizing this being, seemingly human, was actually a highly anthropomorphized machine.
A scarlet monocular on the mask drew a red light in the darkness, Su Ming knowing the enemy's weakness.
"A robot? Garbage..."
With forceful arms, the Godslayer slowly transformed from a Giant Sword into a mallet, towering over and suppressing Blue Gloves, bending his body back unnaturally.
"I'm not a robot! I'm a bionic man! Don't compare me with those soulless things!"
Blue Gloves struggled madly, trying to roll away, but the symbiote spat out a few white bones nearby, directly wrapping around his feet.
Ah, a bionic man... Information acquired...
That's the weakness of the transmigrator, always eager to lecture the 'natives' and correct their perceptions on certain matters, a common ailment among all transmigrators.
"Hehe, a soul? When I tear you apart, let's see if your soul is square or round. You're done for..."
Su Ming swung the mallet, pummeling this Hydra into the ground like a nail, producing a dull thud with each strike, the opponent shrinking with each blow.
The symbiote transformed similarly to a Stand-in Messenger, beginning to spit at the enemy from behind Su Ming, discovering numerous interesting memories in Su Ming's mind, now capable of partially detaching from its Host.
As long as it maintains contact with the spinal nerves, it needn't cling to the Host, able to turn into a pet-like cat or dog, walking alongside the Host.
After the dense sounds of metalworking, all that remained of Blue Gloves were his head and hands above ground, his entire body embedded within.
Strangulation melted open, one end linked to Su Ming, the other coiling around the opponent's neck like a poisonous snake.
On the cold ground, its head turned to glance at Su Ming, as if asking: 'Can I eat now?'
However, the information was still missing a critical piece, this bionic man was merely an errand boy, lacking the capability and intellect to set up worldwide plans, Su Ming needed to know the mastermind behind it from his mouth.
Su Ming transformed the Godslayer back into a Giant Sword, pointing at the enemy's forehead, removing the helmet to breathe in the cool night breeze, speaking softly to the head on the ground.
"Is your master an idiot? Didn't you install a self-destruct feature? Or do you not understand the meaning of sacrifice for righteousness?"
Blue Gloves flailed desperately with weapons formed from his hands, his eyes spewing rage, almost wishing to devour Su Ming alive.
Yet, stuck in the ground, he clearly wasn't in a position for that, surrounded by terrain compacted by Su Ming's immense force, securely trapped within.
"You fool, dare to insult the 'King of Kings'! You're doomed!"
"Hmm... Information obtained, Strangulation, it's time to eat..."
The pitch-black monster promptly revealed a maw filled with sharp fangs, lunging as if laughing maniacally...
