DC Super Hero Girls LEGO shorts S01 E04 Trading Places

Bumblebee and Killer Moth battle over LexCorp. Supergirl, Batgirl and Wonder Woman look to join the fight, but Lena has built a power-nullifying machine to keep them out. After gloating over her still unnamed contraption (she can't decide on a name), Lena declares she'll unleash it onto Super Hero High as soon as it's completed.
