HuMan is the only creature on the whole planet, maybe Universe???

That can think up an idea of a masterfully well created Trap.
Then with due diligence and expertise in design and fabrication, make said Trap.
Having made said efficient, carefully well constructed Trap,...
... then out of sheer ego, HuMan then knowingly falls in too its own Trap!

The most deadly and dangerous fictional character is Sylar due to following attributes:

He can become Stronger, Faster, and Smarter everytime he kill his victims by slicing their heads then he assimilate their brains
he has unfair advantage over everyone else
if he have rapid cellular regeneration, his version have lightning fast rate advanced enough to survive all the injuries even the most deadly ones
Any physical attacks nothing more than just making him laugh
if he got right Powers, abilities, and skills he will completely unstoppable to anyone else even if you are Superman you simply can't stop him
