Warning: SPOILERS for Tiger Division #2Marvel's many superhero teams seemingly fight robots, androids and artificial beings more than any other enemy, but the Korean version of the Avengers finally reveals why the synthetic lifeforms are the ultimate enemy - and the best. Superheroes tend to fight certain enemies more than others, and zombies, demons, and fascists like the Red Skull immediately come to mind. But Tiger Division #2 specifies precisely why robots, out of all foes, are used again and again.
Multiple types of robots exists in the Marvel Universe. LMDs, or Life Model Decoys, are particularly notable in that they appear as a lifelike version of a human or humanoid (She-Hulk memorably battled dozens of Nick Fury LMDs at once). Technically the Eternals are also robots, but they are highly advanced creations rather than the classic metal framed-models like Ultron - another type of android who constantly seeks to upgrade himself. Good androids exist too, such as Vision and Jim Hammond, the original Human Torch.
In Tiger Division #2, written by Emily Kim with art by Creees Lee, the titular team is surrounded by robots after falling into a trap in the previous issue. "They're just robots!" shouts Tae-Won, who proceeds to smash through the torso of a robot. When another team member questions why he's happy that their opponents are just robots, Mr. Enigma responds "Meaning there's no people inside, so we can rip limbs without fretting over fragile human bones." With that, the team goes to work, and the robots are eliminated within three pages; the General is wounded, but as he is the only member of the Korean Tiger Division who is also a mystical giant totem, he recovers quickly.
Robots: The Greatest Superhero Enemies
Mr. Enigma's name may be a mystery, but his line is considerably more transparent. Marvel editorial prefers robots to living beings when it comes to major fight scenes; this allows the Avengers, X-Men, Fantastic Four and other teams to show their full powers without holding back. The reader, being human, identifies with living beings far more than androids like Ultron and Vision, and so is less disturbed by violence happening to robots than the same happening to humans. Artists can depict rather gratuitous violence this way, so long as the victims are simply androids.
The MCU in particular is wise to this trope, and multiple films depict heroes fighting robots (especially the climax of Avengers: Age of Ultron). Additionally, robots can resurrect, in a sense; an android's consciousness can simply be transmitted to a new robotic body, allowing superheroes to destroy the same foe without said foe dying in battle. The Tiger Division may be a relatively new superhero team, but they are already engaging in one of the oldest superhero tropes: punching through a hoard of robots.
