Tiger and Bunny, a Japanese Anime set in a future New York City in which the media and corporate sponsors play roles in the hero business. While it may have aired in 2011, it just now came out on Netflix as a new release.
Not only are the costume designs phenomenal (I especially like Fire Emblem's cape and Sky High's retro-futuristic look) but it really makes you think about how hero's would probably evolve in a media-driven world like we have.
I recommend watching the first episode, at least, to stimulatify your thinkizing.
Here's a trailer on youtube:
Trap Spider - the little spider rides a big robot
Thunderbird Priest - conduit of the Thunderbird spirit
Lovebot - programmed to love man, gives tough love to mankind
Schwarzchild - singularity-manipulating time traveller is lost
