Invincible Season 4 comes to an end after a run filled with explosive dangers, cosmic-level threats, and intense action. It was a long, grueling war, but at the end, Mark and his father, Nolan, survived. However, as hinted in the final episode of the show, it seems the battle is not over. The Scourge Virus, which previously caused massive destruction and nearly wiped out millions of Viltrumites, appears to have evolved. 

The mid-credits scene pulls us into a crucial scene involving Allen and Thaedus, suggesting that the Scourge may now be even more deadly than before.

The mid-credits scene in the finale of Invincible shows Telia bringing a message to Allen and Thaedus, explaining that a new and improved version of the Scourge Virus has been developed. The dead Viltrumite, who had recorded the message only for Allen in case he did not survive, reveals a crucial detail about the virus. And that is, it can also kill species genetically similar to Viltrumites. That said, the virus could be deadly to humans as well. 

He further added that while Nolan was aware of the virus, he likely did not know about this enhanced version and just how it could be lethal to humans, too. At the end, he urged Allen to use the virus to kill the viltrumites. Considering the devastation it previously caused to the Viltrumites, the Scourge Virus is already quite deadly. 

And now, the virus, which is one of the few things capable of killing the Viltrumites, poses a serious threat to Earth, too. But whether the virus will be used or not is something that can be found out in the next season. And fortunately, fans might not have to wait long for it.

A new season of the show, which was announced, has a release window, too. 

The animated adaptation of Invincible will return for Season 5, as announced by Prime Video in 2025, even before the premiere of Season 4. The new season is already in the works and is expected to arrive sometime in 2027. However,  an official release date is yet to be confirmed.

Meanwhile, Robert Kirkman, who is the creator of both the comics and the show, confirmed in an interview with Polygon that the series is planned to run beyond five seasons. While nothing is set in stone, there are discussions about expanding Mark’s story across at least seven to eight seasons. It is an intriguing update, but it also suggests that even greater dangers and challenges lie ahead for Mark.
