I'm gonna go with Tiger and Bunny. It's name is a total lie, for one thing. It's an animê about people called NEXT, who are basically humans with superpowers. It's sort of a classic superhero story, with a veteran hero getting threatened to be replaced unless he partners up with an upstart rookie. Once you get past that, though, this animê takes some turns. The final arc before the ending is really dark, and the segundo season as a whole is an emotional rollercoaster. The animê deals with a lot of heavy concepts like meaning of justice, revenge, and family, but also overlooked ones like how far you go for ambition, and being okay with your sexuality/gender (see the segundo Tiger and Bunny movie. It's a feels fest.) It's a really great animê and I hope mais people watch it. I recommend the dub, as I really don't think the original voice for Tiger does him justice, but it comes down to personal preference.
Oh, and it has one of the most genius ways of doing product placement in the history of everything.
Ragnarok the Animation, an animê which is based on an MMORPG game titled Ragnarok Online. Well, obviously for Ragnarok players this is a recommended anime. Places, classes/jobs and costumes are similar to ones shown in the game. Who's not excited to see their favourite jobs got animated? Non-players who like adventure animê should also watch this.
