The debate is now over, however; Robbie Reyes and Ghost Rider are confirmed for season 4.
There’s been a lot of speculation in the past several weeks about whether Ghost Rider (and specifically, the Robbie Reyes “All-New Ghost Rider” variant) would appear in the fourth season of Agents of S.H.I.E.L.D. when it returns this fall.
Agents of S.H.I.E.L.D. season 4 airs on ABC Tuesday nights at 10/9c, starting on September 20, 2016.
Only time will tell, but Ghost Rider is looking good so far.
