Thanks to Eric Kripke, Supernatural lives on.

It would be strange to compare two shows as different as The Boys and but here we are. Eric Kripke, the creator of both projects, hid several Easter eggs and wove images from Supernatural into the adaptation of the notorious superhero satire.

The appearance of is not the first and far from the only reference to the legendary show.

The most obvious reference is, no, not Jensen Ackles, but Robert Singer, the US Secretary of Defense. He was played by Jim Beaver, who also portrayed veteran hunter Bobby Singer on Supernatural. Moreover, the name of the friend of the Winchester family refers to producer and screenwriter Robert Singer.

Some fans even believe that Robert could be another version of Bobby; after all, Chuck created a multiverse, and who knows, maybe The Boys live in one of the universes.

Besides, Robert's hometown is Sioux Falls, South Dakota, the same place where Bobby lived. Is it just a coincidence?

Eric Kripke personally confirmed that the appearance of Jensen Ackles' character was clearly inspired by Castiel's first acquaintance with Dean and Sam. Castiel reveals himself in the barn, opening the doors wide and showing the shadow of his invisible wings.

It made a huge impression on the audience, and Eric Kripke wanted to achieve the same effect with Soldier Boy.

It seems that it was a smart move, considering Jensen Ackles' nude appearance now ranks as one of the most memorable scenes in the whole show.

In Supernatural, in addition to Sam and Dean, there was another main character – a 1967 Chevrolet Impala.
