How has it taken DC Comics nearly six years to have its current iterations of Batgirl and Supergirl meet? It seems like a no-brainer to team up the two superheroines most heavily associated with DC’s biggest franchises, and it’s finally happening in next week’s Batgirl Annual #1. After tracking a villain to Supergirl’s home turf in National City, Batgirl finds herself in a tricky position as the wiser, older hero who is asked for assistance on a mission that isn’t very well advised. Supergirl wants Batgirl to help her break a potentially Kryptonian psychic prisoner out of a Cadmus black site lab, and while there are a lot of ways this can go wrong, Batgirl would rather offer the teen Kara support than let her do this on her own. Written by regular Batgirl scribe Hope Larson with art by Inaki Miranda and colorist Eva De La Cruz, this Batgirl Annual team-up sets the stage for a new friendship that will be carrying over to the main Supergirl title, which welcomes Batgirl for its new arc beginning next month.
