The MCU just quietly introduced one of Marvel's most popular heroes

The MCU subtly teased the appearance of a hero we’ve been dying to see on the big-screen again.

If you’ve been watching Agatha All Along, the sequel to WandaVision, you’ll likely be watching each episode with baited breath in the hope your favourite supernatural hero/villain gets a cameo of reference.

In the most recent episode we finally, finally got a name-drop for one of Marvel’s biggest bads, Mephisto, but that seemingly wasn’t all.

Some of the most dedicated Marvel fans have dug a little deeper, and decided the Mephisto tease opens the door for another character to join the MCU at a later date, one of my personal favourites too, Ghost Rider.

The Ghost Rider is a spirit of vengeance who’s taken many forms over the years, but his most popular is that of Johnny Blaze, who rides a flaming motorcycle and was played by Nicholas Cage in two live-action films.

Many predicted he'd appear in Doctor Strange: Multiverse Of Madness, and concepts for Deadpool & Wolverine show him fighting alongside the two heroes in the Void.

In the third episode of Agatha All Along it’s said Agatha’s son was traded for the Darkhold by the witch, and could now be an agent of Mephisto.

Why’s this important? Because the person who says this is Jennifer Hale, another Marvel character who’s a descendant of Noble Kale, a Ghost Rider of old.

The Danny Ketch version of Ghost Rider is a descendent of Noble Kale too, hence why he eventually becomes one of hell’s servants later down the line.

Now there’s no guarantee this is all leading up to some sort of climactic Ghost Rider showdown later in the series, but if Mephisto is to become one of the dominant forces in the MCU it’s safe to assume Ghost Rider isn’t far behind him.
