CBS and WBTV have released this new trailer for Supergirl called A Hero Will Rise. A lot of the footage we've seen in other trailers, but the line "Earth doesn't have just one hero anymore…" which we know is Superman… so that puts the shared universe with Arrow and The Flash seemingly off the table.

But if that wasn't enough to crush your hopes… here is a tweet from Gary Levin who is covering the Television Critics Association event for USA Today and posted this in response to things said by Nina Tassler during the CBS presentation.

Don't look for crossovers between #Supergirl and #Arrow, on sibling networks. But they'll run promos for each other. #TCA15 — Gary Levin (@GaryMLevin) August 10, 2015

But where we won't get the Scarlet Speedster and Emerald Archer… we are likely to get two other recognizable characters… General Zod and Red Tornado.

Red Tornado and General Zod are among characters popping up in the #Supergirl universe. @cbs #TCA15 — Gary Levin (@GaryMLevin) August 10, 2015

Update – Levin is quoted as saying General Zod, but the official Supergirl twitter account is confirming Red Tornado and mentioning General Lane… so it is possible that Levin misheard Zod.

CONFIRMED at #TCA15: These @DCComics characters are coming to #Supergirl! Livewire, Reactron, Red Tornado, Non, and General Lane. — Supergirl (@supergirlcbs) August 10, 2015

Supergirl premieres October 26th.
