In Teenage Mutant Ninja Turtles by IDW Publishing, issue #101 begins an unnamed story arc that continues with issues #102, #103, #104 and #105. It is the first complete story arc of the main ongoing series to be written by Sophie Campbell, who became the incoming lead writer for the series after the departures of Kevin Eastman and Tom Waltz from the role. It is also the first complete story arc not to be given a title; some individual issues earlier in the ongoing series were also untitled, but were not part of story arcs except by virtue of being part of the series itself.
