Marvel United: Return of the Sinister Six

Buy this first

Our take: BGG posters in a 2023-2024 cross-season ranking thread name it the best Season 1 expansion (seven villains, a distinct mode); r/MarvelUnited posters repeat it. BGG rates it 8.66 from 725 ratings, the highest of the Season 1 boxes. It is a Kickstarter exclusive, so it is out of print and costs a premium on the secondary market; it adds no heroes.
What you need first: Needs a Marvel United core box: the original Marvel United, or another Marvel United core box such as Marvel United: X-Men.

What it adds: Six new villains: Doctor Octopus, Electro, Kraven the Hunter, Mysterio, Sandman and Vulture. Each can be fought alone, or all six together in the Sinister Six Mode.
