His sword glowed red and grew in length.
He swung it at the guards, destroying their upper torso into pieces. This was his special ability.
Strength continued to walk and kill bystanders, bashing their heads and destroying their legs.
Durability ran through the halls, he glowed blue, he then smashed some dudes with his sword with an overarching swing onto the ground.
From his sword blue orbs came out, the number of orbs depending on how many people he killed, and targeted and killed other scientists and guards. This was his special ability.
An absolute blood bath, whoever walked in their way was killed on sight.
One guard with a katana tried to fight Speed, they clashed swords and did a quick battle, but the guard got his arm sliced off and then his head bashed into giblets by Strength.
Durability also arrived.
They walked through the halls, covering everything in blood and pieces of flesh.
A sort of juggernaut stood in their way and Strength took him on.
The juggernaut initially stopped his sword, but Strength pushed him away, hit him a few times with his sword and used his special ability, snapping the juggernaut in half horizontally and then bashing his head in with a vertical slash.
Durability didn't have much action but continued to summon blue orbs to target other people.
Speed ran through the halls, even going backwards, making sure everyone was killed.
He swiftly slashes whoever he met while running, always with a crazy grin on his face.
Those who survived Speed’s quick death, were met with Strength's dull sword.
It was quick, but for those who watched, it was a nightmare.
Friends and maybe family getting blown to pieces by a sword…
Those who tried to run were met with Durability's orbs that bashed into people, making holes in them and usually blowing them to pieces.
All of this happening with blaring alarms and this epic music playing, and red light everywhere.
I ain't kidding, the music is canon. It plays from an unknown source.
And finally, when they reached the end of that now forgotten laboratory, their swords disappeared and their eyes changed color to gray. They went on their own paths.
Estimated people living and working in the laboratory: 1,250,000
Survivors: 0
If I'd have to paint a picture of the least bloody hall in that lab, I'd have to use so much red paint that I'd run out of it.
Pieces of flesh, organs, bone everywhere.
These three men grew in that lab, seeing other humans torture them with tests and experiments.
