Supergirl’s upcoming crossover with The Flash could prove the TV superhero event of the season, but CBS isn’t about to unleash the “Worlds Finest” just yet. See the first official teaser for the March crossover event, full of … logos!

Entertainment Weekly debuted the first official teaser for the Mach 28 episode, which doesn’t appear to feature any actual footage of the team-up, rather recycling footage from their respective CBS and CW series. Still, fire trails around the Supergirl logo! Logos are still cool, right?

So reads the official March 28 synopsis, which confirms a villainous teamup we glimpsed on set earlier:

Kara gains a new ally when the lightning-fast superhero The Flash suddenly appears from an alternate universe and helps Kara battle Siobhan, aka Silver Banshee, and Livewire in exchange for her help in finding a way to return him home.

We’ll find out more on the road to March 28, so stay tuned for more “Worlds Finest” details of the big Supergirl-Flash crossover!
