Angron is even more Badass than Duke Nukem. he started the First War of Armageddon by rushing around the galaxy with millions of Khorne workshippers. in under 5 years, he conquered 50 planets and slaughtered the population. when he finally got to Armageddon, he was only defeated by an entire company (100 men) of Grey Knight Terminators (1 of those can kill a Greater Demon alone) rushed him. what happened? he slaughtered 97 of them before 1 of the lucky bastards forced him through a dimensional rift. and do you know what? he will probably do it again. and his army killed off 90% of all life on Armageddon (thats about 10 million men).
Edit: oh, i forgot to say his sword is 8 meters long.
