From the World of Minor Threats: The Alternates TP

Spinning out of the world of the hit Minor Threats superhero series created by Patton Oswalt, Jordan Blum, and Scott Hepburn comes a new tale of costumed underdogs—featuring a support group for superheroes, struggling to reclaim their mediocre lives after tasting their true potential.
Mary the Multi-Monster! The Tripper! Crab Louie! Kid Curious! Persona! These offbeat b-list superheroes, formerly known as The Alternates, 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.
Collects The Alternates #1–#4.
