The plans for Marvel animated shows have gotten a bit smaller it seems. Both the Howard the Duck and Tigra & Dazzler series have been canceled by Marvel before they even aired.
Hulu announced plans for four Marvel-based animated series in Feb. 2019: Howard the Duck, Tigra & Dazzler, Hit-Monkey, and M.O.D.O.K. The four series would eventually crossover in a series called The Offenders after their respective first seasons.
In Dec. 2019 it was revealed that the entire writing staff of Tigra & Dazzler has been dismissed over creative differences, and a new team would need to be assembled. It seems, however, that was just the start of the adjustments as two of the series are officially dead.
For a long time the Marvel films and TV series put on a public face that they were all connected, but the films (Marvel Studios) and TV series (Marvel Television) were different divisions. While the TV side would occasionally reference the films, it was never a two-way street. Last Oct., that changed as Kevin Feige became the Chief Creative Officer of all things Marvel and not just the films. Since that time he has been cleaning house a bit.
The planned Ghost Rider series was canceled prior to production, but the upcoming Helstrom has survived the ax for now. Cloak & Dagger was canceled at Freeform, Runaways met its end at Hulu, and New Warriors never got past the pilot stage at Freeform.
While cancelations seem to be happening at a brisk pace, Marvel is definitely not done with television. There are multiple series in various stages of production over at Disney Plus, so there will still be Marvel on your TV in the future, it will just be in a very different form than years past.
