Warning: This article contains minor spoilers for The Punisher Season 2, now streaming on Netflix.

Even though Stan Lee passed away a few months ago, tributes to the legendary Marvel creator are still pouring in on a regular basis from the real world and the various corners of the Marvel Universe.

While Lee never had the biggest role in Marvel's Netflix series, the last episode of The Punisher Season 2 ends with a brief tribute to the writer, editor and comics ambassador. At the end of  the 13th episode, "The Whirlwind," Jon Bernthal's Frank Castle begins shooting into a crowd of criminals and lets out a primal yell. As the screen fades to black and the show's guitar-driven score kicks in, a brief card reading "In loving memory of Stan Lee" fills the screen.

Given The Punisher's uncertain chances of being renewed, the Stan Lee tribute could very well be the last moment of the Marvel Cinematic Universe series.

This simple, somber tribute is similar to the ones included in Spider-Man: Into the Spider-Verse and Marvel's Runaways Season 2, it's worth noting that Lee didn't play an active role in creating the Punisher, who was created by Gerry Conway, Ross Andru and John Romita in 1974's Amazing Spider-Man #129.

Despite Frank Castle's numerous appearances on film and TV, Stan Lee's only cameo in a Punisher production was in The Punisher Season 1, where he could be seen on a recruitment ad for the United States Marine Corps.

While he didn't make an appearance here, Lee reportedly filmed a few more cameos for Marvel films before he passed away in November.

The Punisher Season 2 stars Jon Bernthal as Frank Castle, Ben Barnes as Billy Russo, Amber Rose Revah as Dinah Madani, Deborah Ann Woll as Karen Page, Jason R. Moore as Curtis Hoyle, Josh Stewart as John Pilgrim, Floriana Lima as Krista Dumont and Giorgia Whigham as Amy Bendix and is now streaming on Netflix.
