The team will deal with a very powerful Eli Morrow in the upcoming episode of "Agents of S.H.I.E.L.D." season 4.

In episode 7, Eli Morrow will have already acquired the Darkhold and the team must think fast to prevent him from threatening and mercilessly killing people.

Episode 6 focused largely on the origin story of the Ghost Rider. The episode followed Robbie Reyes a.k.a. Ghost Rider as he took down Lucy Bauer. However, his uncle Morrow seemed to have gotten much stronger after taking advantage of the Darkhold to facilitate his mystical plans.

The promo video for episode 7 shows that Morrow will be the biggest threat that the team will have to face next.

The 10-second teaser clip says that the Spirit of Vengeance will continue his demonic quest and that the team has to gear up for a lot of dangers, especially now that Eli is keen on destroying everything that will attempt to get on his way. The previous episode revealed that the person behind the Momentum Laboratory was actually Morrow, after Coulson and the others initially thought that it was either Lucy or Joseph. As it turned out, it was Morrow who ordered the attack against Joseph and had the scientist beaten up for refusing to disclose any information about the experiment.

The end of episode 6 saw Morrow covered by white energy in chamber. As episode 7 opens, viewers can expect him to have already gained the power to create carbon out of nothing. Capable of killing anyone without remorse, the team must find a way to take down the pure evil that he has become.

"Agents of S.H.I.E.L.D." season 4, episode 7 airs on Nov. 29 on ABC.
