Username WonderWoman tweeted photos of Team Flash consisting of Barry Allen/The Flash (Grant Gustin), Wally West/Kid Flash (Keiynan Lonsdale), Jesse Wells/Jesse Quick (Violett Beane) and Cisco Ramon/Vibe (Carlos Valdes) in a CG fight between Gorilla Grodd and season 3's main villain Savitar.

The BTS photos sees Cisco now wearing his full superhero Vibe costume during their fight and recruiting both Jesse and Wally would mean that Flash will need all the help he can get to beat them. Their also another interesting factor in the BTS images as two unknown characters are present during the shoot.

First is an unknown woman wearing an all-black outfit and it is unknown if this person is a villain, a metahuman from the Flashpoint timeline or an ally of Team Flash. The second character is speculated to be another speedster as the Twitter page of YRRShoots tweeted an image of the individual who has the striking resemblance to the "Justice League 3000" version of The Flash. With the concept of the multiverse already present in the show, perhaps this speedster will help Barry fight Savitar and Grodd.

In other news, it seems that a death of a main character is teased in the second haft of "The Flash" season 3 as Barry's love interest Iris West (Candice Peyton) could be in danger very soon.

Twitter username The Flash Brasil posted photo of Barry holding what appears to be the lifeless body of Iris with a mocap person on the background, which could be Savitar himself.

Savitar made it a point to target Barry and his friends during their encounter with him throughout the show, with the help of Doctor Alchemy, who is eventually revealed to be Julian Albert (Tom Felton), ComicBookMovie reported. Could Iris be the latest casualty in their fight against Savitar and Alchemy?

The winter finale of "The Flash" season 3 will feature Barry travelling to Earth 3 and seek the help of Jay Garrick (John Wesley-Shipp) in his fight against Savitar and Alchemy.

"The Flash" returns on Tuesday 8pm ET on the CW Network.
