This is the Cube Man, always carrying a cube and acting alongside the Riddle Man, a monster.
To call him a monster is because his strength is simply too powerful.
The devices of mankind stand no chance against him.
The appearance of Cube Man alarmed the fifth level.
With the FBI's call for help, the Evolution District dispatched dozens of B-level test subjects, and even included a few A-level ones.
This was the first time Lincoln Fortress had deployed such a number of test subjects for a single criminal.
In a sense, these test subjects are the superheroes of this fortress.
Although behind these superheroes, there are groups of scientists who have little regard for morality.
But, it's evident Lincoln Fortress's officials underestimated Cube Man's strength.
This monster, who seemed to be pondering some cosmic puzzle while fiddling with his cube, easily annihilated all the test subjects.
And being in league with Riddle Man made his whereabouts extremely elusive.
