From the World of Minor Threats: The Alternates

Mary the Multi-Monster! The Tripper! Crab Louie! Kid Curious! Persona! Formerly the offbeat b-list superheroes, The Alternates, who seemingly sacrificed themselves to stop an invasion from another dimension. Instead they were transported to a mirror reality where they lived complex lives in a more four-dimensional existence--expanding both their powers and consciousness. Five years later they've returned to Twilight City, struggling to reacclimate to their old lives in a traditional two-dimensional superhero world--in withdrawal from the vivid ones they left behind. When elements from this alternate reality turn up as a dangerous new street drug, some of the heroes band together to destroy it, while others succumb to its temptation.
