I wasn't sure about the level of detail for tagging in an image with that many characters, I tried to tag features that appeared in more than one character, or prominent ones like the starters.

The characters grouped next to each number were released on the event that happened at the respective anniversary, except for the 5th one, that hasn't happened yet.

Or be like me, tag all of them (like post #5022581).
