The Arachnid And The Terrapin

May "Mayday" Parker is new to New York, since having moved with her parents, Peter and Mary, from the UK so Peter could pursue his new job in the establishment TCRI and help Mary expand her acting career.

Soon, May starts at a new school in Manhatten. Feeling slightly isolated, she meets April and they quickly become friends, hanging out, sleepovers, studying. May finally feels like she belongs.

However, one night when walking home with April and her dad, they're kidnapped by robots controlled by aliens called "The Kraang" alongside meeting four turtle brothers, who save the two girls, they all work together on the missions and mysteries surrounding the capture of April's father, Peter's job at TCRI, and conflicting feelings between the girls and the turtles, especially May and Leo.

May seems to spend most of her time with Leo, being more than close friends is apparent to most people over time, but neither say how they feel. Especially with the arrival of Karai and her father, the Shredder, there's no time to admit feelings or even denying what's really going on in their hearts.

One day on a school trip to TCRI with special access, courtesy of Peter, the turtles see it as a perfect opportunity for April, May and their new friend to investigate without being detected. When watching the animals and insects being experimented on, a spider laced with the same mutagen that affected the turtles bites May, causing her to faint and call the mission a bust.

After May regains her strength, she discovers her new abilities, which soon become hard to control. With the help of Leo and the other turtles, she becomes a new vigilante, known as Spiderwoman.

Now that the Kraang and Shredder know about Peter Parker's work, he unknowingly becomes a tool to help their plans...

Each day is a new mission and struggle. Defeating new mutants alongside working out the Shredder's plan to destroy the turtles, May helps out, no matter the cost...
