We should have a "Santa versus our characters" special event that's like "defeat the godmodder" or whatever it is. Each year someone else gets to be Santa who won the winter tournament. Santa's abilities can be interpretted by however is controlling him, from having ice powers to duel wielding giant candy canes to time controlling powers (which he obviously must have to deliver all the presents). He will likely be very OP but has to have some exploitable weaknesses.

I'm planning on another "main" character who can control points, which are basically small points in space that can destroy less powerful things coming in contact with it. He can make the points bigger and move them around as he grows in skill. They will of course be visible, but could be hidden within other objects. Think very slow moving bullets that you don't want touching you. He may be able to repel or attract things to it, which makes it seem similar to gravity magic but it's not truly (in before, "but it is gravity magic, you liar!!!"). He'll have good synergy with others, like attracting Evvie's fire around it to send out fireballs. Every main hero always needs a good scene where they can combine powers with their friends to dramatically defeat the boss, preferably while they're all shouting.

My character a day will be rebooted starting next year. They will get new numbering and such and I won't actually post one a day, but I'll get them done in a much more timely manner. It will be more like a regular database filled with characters I can actually care about.
