More than likely the teaser is for Hellfire, and honestly I would much rather have Ghost Rider in the MCU than on TV, but Agents of SHIELD has teased a flaming chain for Comic-Con.
The SHIELD Twitter account released a pic of a San Diego train adorned with SHIELD art with a flaming chain.
Hellfire has already appeared in the series using said chain and was involved in the Marvel Comics Secret Warriors comic book storyline.
It's possible Hellfire could have a larger role for Agents Of SHIELD season 4.
There has been lots of talk surrounding Ghost Rider as of late because the rights to the character are back with Marvel. Norman Reedus said a big "f' yeah" to playing the character, and even X-Men's Shawn Ashmore said he would like to play the Spirit of Vengeance.
We'll find out more next month when Comic-Con takes place July 20-24.
