Nobody really took account for how dangerous Leo's portals could be when he used them. Nobody asked how they worked, if they go much further than just teleporting around a city. So when the four turtles were training and Leo used a portal to jump his younger brother Mikey from behind and didn't come out, a panic arose. I think the cover is by unknown plants on tumblr, this is a temporary cover bc I just wanted to write something on a whim. I hope you enjoy!! &ltsdhfo
