The CW had a big weekend at San Diego Comic-Con. Here are just a few highlights and trailers.

• "Supergirl"
"Supergirl" is making history with the first transgender superhero. Transgender activist and actress Nicole Maines was cast in Season 4 as Nia Nal (aka Dreamer), described as "a soulful young transgender woman with a fierce drive to protect others." Other new series regulars were announced Saturday: April Parker Jones (as Col. Haley) and David Ajala (as Manchester Black). "Supergirl" returns Oct. 14 at 8 p.m.

• "The Flash"
"The Flash" Season 5 is adding Chris Klein -- remember him, from "American Pie"? -- as the new villain Cicada. According to The CW's press release, "next season’s scourge of Central City" is a "grizzled, blue-collar everyman whose family has been torn apart by metahumans." And he's looking "to exterminate the epidemic — one metahuman at a time." "The Flash" returns Oct. 9.

• "Riverdale"
"Riverdale" Season 3 cast Penelope Ann Miller in the recurring role of Mrs. Wright, the district attorney prosecuting Archie Andrews for murder. She's described by the CW as “savvy and eloquent,” and “with a conviction in mind, she will weave together disparate moments of Archie’s young life to portray him as a dangerous, violent sociopath who is capable of committing a heinous crime.” "Riverdale" returns Oct. 10.

• "Arrow"
The "Arrow" panel confirmed that the Longbow Hunters will be introduced in Season 7. According to EW, the Longbow Hunters are a legendary group of assassins Ricardo Diaz (Kirk Acevedo) recruits to get back at Team Arrow. The three assassins are Red Dart (Holly Elissa), “a ruthless and precise killer"; Kodiak (Michael Jonsson) “a beast of a man with brute force”; and Silencer (Miranda Edwards), a master of stealth. Bronze Tiger (Michael Jai White), Derek Sampson (Cody Runnels), and Danny “Brick” Brickwell (Vinnie Jones) all returning this season as well. "Arrow" returns Monday, Oct. 15.
