At Mortal Kombat 11's reveal event today, series creator Ed Boon showed off new character customization options the developers have added this go-round. You'll be able to "create, modify, and collect multiple versions of every character," Boon explained. This starts with different skins, or outfits, for each character, and the characters also have three costume pieces. In Scorpion's case, that's a face mask, katana, and his "get over here" spear.

Your customization will show up in battle, and it seems like there's also more than just cosmetics at play here. Each piece of equipment has three "augment sockets" you'll be able to do something in.
