Darkseid is an oft enemy of Superman and the Justice League. Deathstroke is an enemy for the Teen Titans, but shares billing with the Bat family. Due to this, he has something of a special enemy for Nightwing.
The original proper Hydra popped up just around the ends of WWII as the remnants of the Axis powers, notably Nazi Germany and Imperial Japan. The primary factions are concerned with world domination, either through large strikes or subterfuge or just general terrorism to throw off the balance and make events favorable to them.
Hydra had been around before that though as different, intermittent, and more mystical societies. But their general goal has remained the same.
The marvel universe (General bystanders, and other heroes) view on the Winter Soldiers, Task Master, Deadpool, Frank Castle, and DareDevil. Good, Bad, something in between?
The Winter Soldier isn't well liked at all. Though he went to space for some time and now he's hanging out with the Thunderbolts. He's still not very liked.
Taskmaster was seen as a hero like figure ONLY during Civil War. Aside from that he's seen as a terrorist or criminal.
Deadpool is generally seen as a criminal or a nuisance, though his inclusion on the Avengers (and the real world's feelings about him) have alleviated quite a bit of this.
Frank Castle is seen as a straight psychopathic killer to the vast majority of the Marvel universe. To the point several heroes only team up with him as absolutely necessary.
Daredevil is something of an oddity. Most think of him as a hero, though some see him as something more leaning of a vigilante.
How well did you think William Dafoe and JK Simmons pulled off the Green Goblin and Jameson (respectively) roles in the movies?
What are your favorite comics that don't involve superheroes/villains?
The Wicked + The Divine
I'm pretty torn up, because I also wanted to add Y: The Last Man, Bitch Planet, Love and Rockets (guilty pleasure), Red Sonja (the non-Marvel one), and a few others.
They should have also added Spider-Man vs. the Public Opinion.
