"Pic of the day. Long before the game release, we revealed new fighters with videos. The video quality of online streams is not always the best, though. Luckily, you can watch them as they were meant to be in Movies mode on the Wii U version.
You can even re-watch videos that play after you clear Classic mode and Allstar mode. This is a list of videos which are unlocked when you clear certain things. They tend to be short, but you’ll get a lot of information if you play them all in one sitting."
