‘Arrow,’ ‘The Flash,’ ‘Supergirl,’ ‘Legends of Tomorrow’ Crossover Spoilers: Kara, Heat Wave’s Dynamic Teased In New ‘Invasion!’ Trailer

Heat Wave (Dominic Purcell) is seemingly not a fan of Supergirl (Melissa Benoist).

In a new trailer for next week’s crossover event between “Arrow,” “The Flash,” “Supergirl” and “Legends of Tomorrow,” Heat Wave, a.k.a. Mick Rory, lets Kara Danvers know that he doesn’t like her superhero name, Supergirl.

“I’m not gonna call you Supergirl. [It’s] stupid,” the heat gun-wielding Legend tells the Kryptonian in the promo clip.

“How did you get the name Heat Wave?” Kara asks him in response.
