'Supergirl' Spoilers & Updates: More Connections With The Flash, Arrow, Legends Of Tomorrow & Hawkgirl; Who is Cyborg Superman?

It looks like the "Supergirl" series had been dropping major spoiler as well as big and exciting hints. Fans may have already know about the crossover of "Supergirl",  Barry of the "The Flash", Oliver Queen of "Arrow" , and the heroes "Legends of Tomorrow" , and new superheroes might be joining the fun too, let's say Justice League's Hawkgirl and Hawkman?

The upcoming crossover of the major superhero series will be on November 28, Monday. The latest episode of "Supergirl" though had lots of hints that would fascinate the minds of the fans. Cyborg Superman had entered the show, Hank Henshaw had a few upgrade and ended up calling himself as Cyborg Superman.

Henshaw had used the blood of "Supergirl's" Kara to get the necessary information that Superman has about the Project Medusa. Also, Jeremiah Danvers, played by Dean Cain, is also back for a short time to save Kara and Mon-El escape the Project Cadmus. From the Project Cadmus the major hint, the word 'Thanagar', got "Supergirl" fans to trace the connection to one major superhero world.

From the last episode of "Supergirl", Mon-El mentioned to Supergirl (Melissa Benoist) that she won't be able to break the cage as it was made from Nth, which is a Thanagarian metal. Supergirl wasn't surprised and so some viewers had just look passed it but actually, this is a major thing. Thanagar is the home planet of Hawkgirl and Hawkman. From this, those two may be involved in the series or this just points to the importance of "Supergirl" in "Arrow".

The "Supergirl" series alone have heated up its sleeves and with the crossover with "The Flash", "Arrow" and "Legends Of Tomorrow", the crossover event will be like watching "Avengers" and "Justice League". Although Supergirl had a bad start with HeatWave the heroes would seek help from each other and form a team to defeat the enemy that may be the strongest of all they could ever meet.
