Teenage Mutant Ninja Turtles Shredder (2025) #3

Plot

The Shredder’s quest to find the rogue Foot soldier “the Mourner” takes him to Europe, where she is rumored to have procured some top-secret technology from a very distant place — Dimension X — to use in the mysterious device she’s constructing. For what purpose, only the Mourner knows for sure, but it’s one the Shredder is determined to undermine at all costs.
