There's been no shortage of guest stars in this season of
Marvel's Guardians of the Galaxy: Mission Breakout! and ahead of the season finale tonight, Marvel has announced one more. Legendary actor Henry Winkler (
Happy Days) is set guest star as Peter Quill's grandpa in at least one of tonight's episodes.
While we have no other details about his role in the show, tonight will feature a three-part finale that will finally conclude the Guardians' ongoing battle with The Serpent. This epic story arc has been ongoing for a few weeks now, dating back to Guardians' fight against the Darkhawks (which The Serpent was responsible for) which began in May.
Tonight's episodes will not only conclude this arc, but the third season of
Marvel's Guardians of the Galaxy: Mission Breakout! as well. Marvel has released a new clip from one of the episodes, but it sadly does not feature a sneak peek at Winkler as Quill's grandpa.
“Breaking Stuff is Hard to Do” (9:30 – 10:00PM ET/PT)
With reinforcements gathered, the Guardians and their friends head out to find the fragments of Dragonfang – a legendary weapon that will finally be able to defeat The Serpent forever.
“Killer Queen” (10:00 – 10:30PM ET/PT)
The Guardians team up with Loki and Iron man and travel to the castle of the evil Hela to seek her aid in fighting The Serpent.
“Just One Victory” (10:30 – 11:00PM ET/PT)
The Serpent is using the power of Asgard to siphon energy from the galaxy, destroying planets one by one. With the Nova Corp defeated and the fate of the entire universe in jeopardy, the Guardians must turn to an unlikely ally to stop the Serpent.
Marvel's Guardians of the Galaxy: Mission Breakout! airs tonight on Disney XD and DisneyNOW! starting at 9:30 p.m. ET/PT. Have you been watching the animated series?
