‘BoJack Horseman’ Spoilers: Season 4 To Feature A ‘New’ BoJack

"BoJack Horseman" is finally back.

After waiting for over a year, "BoJack Horseman" Season 4 is finally airing this week. But its main character BoJack Horseman (Will Arnett) will be missing in the first episode and will be seen in a different light when he returns.

In this promo clip, Diane (Alison Brie) is talking about BoJack's absence. According to her, she has never heard from him for three months. A lot of things have changed without him and things become crazier. Series creator Raphael Bob-Waksberg confirmed to Slash Film that the main protagonist will be kept hidden in the first episode. That is why they are marketing the phrase "Where's BoJack."

"It felt like a fun thing to try, to have a show called BoJack Horseman and have no BoJack Horseman for an episode," Bob-Waksberg said. "Yeah, that's the kind of thing we do. Let's go for it."

BoJack's absence will give him some time to find himself. According to Den of Geek's review for "BoJack Horseman" Season 4, BoJack will evolve as a character.

The series is about BoJack, a self-loathing horse who dwells in his misery that he becomes toxic to everyone around him. The titular character is an epitome of the anti-hero. But things might change in the new season.

In the clip, Hollyhawk arrives and is looking for BoJack, whom she claims is her dad. BoJack will reportedly segregate himself from Hollyhawk and his mom who has always been there for him. Without any support system, he will see how the other characters move on easily without him. Sadly for him, he will realize that he needs them more than they need him.

The new season will cover the topic of family and repairing one's foundation not only in BoJack's case but to some other characters in the series as well. This will be explored in different ways.

Although that sound dramatic, the series is a sitcom, so there will always be something that will surely make the viewers laugh. Bob-Waksberg teased that there will be celebrity jokes in Season 4.

"There are definitely jokes throughout the run of the show, even in season four, that I go, 'Oh, that's a little mean. That was a low blow' But if it makes me laugh, I'll put it in," he explained. "I don't know. If someone came to me and said, 'Look, you made that joke about me and that really hurt my feelings,' I would feel bad. That is not our intention with a lot of these celebrity jokes."

"BoJack Horseman" Season 4 premieres on Friday, Sept. 8 on Netflix.
