In early January, TFW2005 revealed to the fans that Decepticon Barricade is prominently featured in licensed merchandise for the upcoming Transformers: Bumblebee movie. This hinted toward a possible appearance of the character within the movie itself.
Sure enough, Jess Harnell (the voice of Live Action Movie Series Barricade), who spoke during a panel at London ComicCon 2018, has confirmed his involvement with the new film and reprising his role as the Decepticon enforcer.
Barricade is also listed as a toy for the Bumblebee movie Energon Igniters gimmick line.
