Robert Kirkman, creator of the "Invincible" comic, confirmed at the Annecy Festival that Jack Quaid, known for "The Boys" series, will join the cast of the fifth season. He will voice Gravitator — a talented engineer capable of controlling gravity. During the panel, an exclusive clip featuring the new character was also shown to the audience, but it has not yet been released publicly.
In the original comics, Gravitator initially acts as an antagonist to Mark Grayson, but later switches sides and begins collaborating with the Pentagon.
The fifth season is expected in 2027. Aaron Paul will also return, once again voicing Powerplex. Additionally, Prime Video has officially renewed the series for a sixth season.
