Legends of Tomorrow really cleaned house at the end of their first season.
Some of those new possibilities include the arrival of Rex Tyler/Hourman, a member of the Justice Society of America, who had been sent through time to save the Legends from certain death.
Introducing the JSA was a bold move for Legends of Tomorrow and hopefully broadening their DC character base will serve to retain a more invested audience.
The Flash season 3 will premiere Tuesday October 4th at 8pm on The CW, Arrow season 5 will premiere in the same time slot on Wednesday October 5th, Supergirl season 2 on Monday October 10th, and Legends of Tomorrow season 2 on Thursday October 13th.
