What it's about: Several hundred years ago, humans were nearly exterminated by Titans. Titans are typically several stories tall, seem to have no intelligence, devour human beings and, worst of all, seem to do it for the pleasure rather than as a food source. A small percentage of humanity survived by walling themselves in a city protected by extremely high walls, even taller than the biggest Titans. Flash forward to the present and the city has not seen a Titan in over 100 years. Teenage boy Eren and his foster sister Mikasa witness something horrific as the city walls are destroyed by a Colossal Titan that appears out of thin air. As the smaller Titans flood the city, the two kids watch in horror as their mother is eaten alive. Eren vows that he will murder every single Titan and take revenge for all of mankind.

Where to Watch: 59 episodes (98%) are available to watch free online (Adult Swim, Crunchyroll & Tubi TV). 59 episodes (98%) are available to stream on a popular subscription service (Netflix, Hulu & Crunchyroll). 47 episodes (78%) are available to stream on a TV everywhere service (Adult Swim). 59 episodes (98%) are available to rent or buy from $0.99 on 5 services (iTunes, Google Play & 3 others).

What it's about: Saitama is a hero who only became a hero for fun. After three years of “special” training, though, he’s become so strong that he’s practically invincible. In fact, he’s too strong—even his mightiest opponents are taken out with a single punch, and it turns out that being devastatingly powerful is actually kind of a bore. With his passion for being a hero lost along with his hair, yet still faced with new enemies every day, how much longer can he keep it going?
