Recently, at The Cosmic Circus, they have revealed that fan-favorite monster Man-Thing is expected to appear in the Werewolf By Night Halloween special. The report states that his appearance will only be a cameo for the 1-episode special.
This comes off long-rumored reports that Werewolf By Night was expected to appear in the Moon Knight Disney+ series. However, with only one episode left, it is unknown if that will happen. A cameo by actor Gael García Bernal as Werewolf By Night would help solidify Moon Knight into the larger MCU. The series has yet to have a single mention of any other heroes beyond Moon Knight himself. Finally, the report states that both Werewolf By Night and Man-Thing will use both practical and CGI effects for the characters.
