Mister Kline the Assassin (Marvel Comics) in the shadows

Mister Kline the Assassin


Mister Kline the Assassin appeared in Marvel Comics in 1971-1972. It was a terribly mysterious story that involved the height of genre cool back then – killer robots, time travel, rewriting history, political manipulation, nothing being explained, and characters called “the Assassin.”

This G. Conway story is also in some ways a precursor for the big annual crossover events. These became a staple of Marvel’s schedule in later decades. Though back then the Marvel books were siloed, Conway was writing a half-dozen of them and used that to pull off a then-rare move – a story that took place across multiple issues of both Daredevil and Iron Man.



  • Marital Status: Unrevealed.
  • Known Relatives: None.
  • Group Affiliation: Agent of Baal.
  • Base Of Operations: Switzerland.
  • Height: 6’2” Weight: 300 lbs.
  • Eyes: Brown Hair: Brown

Powers and Abilities

The Assassin is an android with superhuman strength. His eyes can shoot energy beams.

He’s pretty good at manipulating people, especially if one realises that he doesn’t grok  human beings. The Assassin is primarily a schemer and manipulator.

In combat the Assassin tends to stay on a near-fanatical offensive. In DC Heroes RPG terms he will Press the Attack whenever he can. He favours his eyebeams over close combat, even though they seem less accurate.

We, robots

Kline has the skills and resources to build advanced androids. These will usually believe themselves to be human, which is likely why they seem psychotic. Or perhaps all templates for human personalities available in the era of Baal had psychiatric and faith issues, including Mister Kline.

Three such androids have profiles on WORG :

Alternatively, it is possible that all three were originally human beings who were rebuilt as robots or full conversion cyborgs so they could serve as agents. If so, they are unaware of this.



Circa the 120th century, the computer Baal was created to govern Earth. However, after two millennia, Baal was alone. Humanity had either perished or abandoned its homeworld.

Hoping to alter history to prevent this, Baal sent android MK-9 back over 12,000 years. MK-9 was to set in motion events whose repercussions would affect Earth in a hundred centuries.

As “Mister Kline,” MK-9 worked with XXth century scientists to mutate superhuman operatives. These included “Bull” Taurens, a ruffian whom Daredevil (Matt Murdock) had prevented from abducting test subjects.

Mutated into Man-Bull, Taurens attacked Daredevil. But Kline was more interested in Daredevil’s friend, D.A. Foggy Nelson. He blackmailed Nelson over a past impropriety, to undermine his gubernatorial aspirations.

Robot attacks

Meanwhile, two Kline operatives, the clawed Slasher and the telepathic Demitrius, sabotaged buildings. These had been designed by industrialists Tony Stark and Ben Crandal, who were to be discredited. However, they were defeated by Iron Man. When Stark testified in Washington, D.C., the two attacked the Capitol but Iron Man again prevailed.

Nevertheless, Senator Ernest McJavit (actually a Kline-created android replacement) used the fiasco to discredit Stark and Grandal.

Mister Kline recap panel

Back in New York, where he had carefully cultivated a reputation as a criminal mastermind, Kline entrusted Daredevil’s abduction to the Owl. But the Owl tried to kill his foe instead. Kline then arranged for Daredevil’s rescue by the Black Widow, whom Kline hoped would romance Daredevil as part of his plans.

Returning his attention to Iron Man, he assigned the enigmatic Mikas of his “Mutant Sector” to abduct Stark’s girlfriend Marianne Rodgers. This lured Iron Man into a trap. Kline hoped to make Iron Man his anti-military pawn.

However Mikas, maddened by his own power, tried instead to kill the hero. Stark released his armour’s full energy to destroy Mikas’ base.

Machines and machinations

Kline fared better with an android Scorpion duplicate. It lured Daredevil and the Widow into battle, then fell to his “death,” implicating the Widow for murder.

While Nelson, directed by Kline, prosecuted the Widow and Matt Murdock defended her, Kline sent a Night Phantom android to threaten Iron Man and Rodgers. He then sent a Mister Hyde android to destroy the Scorpion android’s “corpse”.

With the “victim’s” body destroyed, the charges against the Widow were dropped, again at Kline’s orders, damaging Nelson’s career.

As anticipated, feelings developed between Murdock and the Widow. Thus, whilst the Widow vacationed in Switzerland, Kline approached her as scientist Emil Borgdsky. He told her about a cure for blindness. Murdock thus came to Switzerland.

Apparently, Mister Kline knew that recovering his sight would end Daredevil’s career. This apparently would have significant effects on the timeline , advancing Baal’s plans.

The CLXXth century, of course

But Daredevil discovered MK-9’s base while the android was busy conferring with Baal over time radio. Kline revealed his android nature and attacked, but received a head injury.

Mister Kline the Assassin (Marvel Comics) and the Baal super-computer of the future

As Kline struggled to repair himself, the empathic Final Sons of Man came in from the 170th century. These were two metallic, armored or robotic “new people”. Their goal was to ensure that Baal’s future would lead to their own, by destroying Kline and his base.

They then teleported Daredevil and the Widow to safety and departed.

Although Kline is no more, the full extent of his operations was never determined. Thus the ultimate effects of his activities upon the future cannot be predicted.


Note that Mister Kline is a chain smoker, unlike most androids I know. He uses a short cigarette holder.


The Assassin is a strange cross between :

  1. A scheming organised crime type, making threats and alliances as he moves his pawns.
  2. An android who knows relatively little about human nature.

He eventually decided to build robots rather than use human criminals such as the Owl. That was due to the unreliable and unpredictable nature of humans.

Kline seems to have a near-religious reverence toward Baal. When Baal was pleased with his successes and told Kline he was no longer a mere android but could wear the title of the Assassin, Kline did so with enormous pride.


“You won’t make the Owl’s mistake —! You shall stay true and faithful — and obey — the law of Kline !”

“I’m afraid that thought is academic, Nelson… you can’t… and as long as you’re mine, you’ll never think on your own again. From this day forth — you are an agent of the Assassin !”

“Soon, the very shape of our future world will be changed, master… and the history that will make you the sole occupant of the Earth twelve thousand years from this date will be destroyed !”

“Speak all you will ! It was that kind of useless talk which caused the end of the human race. When men should have thought, the only spoke ; when they should have acted, they only wailed !”

“Your flight us useless ! Baal is supreme — and the Assassin is Baal’s sole and perfect agent !”

“The time for Stark to be removed — has now arrived. So speaks Kline. So speaks the Assassin ! Aye ! Now stands the master revealed. Indeed, I am an android — and the truest irony is yet to be given you, Mikas. Prepare yourself — and them — for the hour of Doomprayer !”

DC Universe History

The obscure Professor Menace, a early 1960s Wonder Woman and JLA foe, could be used as the base for a DCU version of the Assassin. He already has robot duplicates of contemporary villains that could be used. For instance Mikas the Soulfather could be an evolution on his Doctor Destiny android duplicate, based on whom Doctor Destiny will become decades later.

His 1960s forays against the Amazing Amazon and her friends as “Professor Menace” could have been but a stepping stone toward a more complex plan during the 1970s as Mister Kline, based on the Marvel story and targetting… Wonder Woman and Aquaman, or something along those lines.
