User blog:Lover of the Muse/Free for All

Free for All (フリー・フォー・オール, furī fō ōru): allows for the sharing of other people's quirks. Before the user can access another persons quirk they first need to establish a 'link' by making physical contact.

If the Free for All user then links with second person, then not only will the user be able to acess both of his targets quirks but his targets will also gain access to each other's quirks as well. The same principle applies if user links with three or more people.

Although Free for All needs to touch somebody to establish a connection, the user can choose to sever that connection at any time. Free for All also has a limited range (20 meters/65.6 feet maximum) and if you go outside of that then the connection is broken. In order to reestablish a link, Free for All would need to touch you again.

The transmission of power between people that Free for All is linked with is automatic and isn't something the Free for All user can control. Unless you happen to be a One for All holder then it's not possible for you to prevent you're own quirk from being transmitted (this is due to the feature of One for All which prevents it from being forcibly stolen). Quriks are physical abilities and Free for All is no exception. Maintaining a link requires physical effort and induces stress. It's like carrying a weight and the more people the user is connected with the heavier it becomes.

Free for All can technically be used in single combat and to access the quirks of opponents, but it works best when it's being used on team so that teammates can share each others quirks.
