The Othersiders is an AU 130k dead fanfic, in which every Undersider has a different interpretation of another Undersiders power. For example Lisa has a Thinker power mapping all nerves in a body which shows her where to strike to exploit all weaknesses, Taylor has unlimited multitasking, etc. The trigger events are different, so differing backstories, personalities and group dynamics. Alec is leader. I haven’t read it yet, but I hear it’s quite good. Major spoilers for you, of course 🙂
Interesting. It’s not quite what I was talking about re: the Othersiders (as defined in 15.2) presumably being a recurring fanfic trope, but it does sound pretty cool!
