Ants in Pants!
Betty, Queen of the Ants, leads the ants of the City in revolt - it loses its major defender when the Tick is thoroughly creeped out and checks himself into Captain Sanity's Superhero Sanitarium. Betty and her minions capture the other heroes and lock them up in a giant People Farm, then collect enough glass to build a giant magnifying glass and use sunlight to fry them. Fortunately the Tick regains his (normal) sanity in the nick of time and saves the day.
