The intro for Attack on Titan is crossing up more often than Daigo. Naturally, a lot of those crosses coincide with videogames. This Super Mario Bros. 3 mash up might lack a certain panache, but it's a nicely done animation all the same.
There's no giant Resetti menacing folks, but it's good. Have a favorite of your own to hold you over until the next episode? I'm rather partial to the Christoper Walken x Attack of Titan. Hopefully they use that for the upcoming Attack on Titan 3DS game.
