The 2023 San Diego Comic-Con is a considerably pared-down affair for the usually massive fan event. With ongoing strikes for both the Writers Guild of America and the Screen Actors Guild, most of the major studios decided to cancel their SDCC participation.

But even without Disney, Universal, Netflix, and Sony, there were still plenty of new trailers debuted for upcoming shows and movies. Here are some highlights, which we’ll be updating throughout the weekend.

Adventure Time: Fionna & Cake

This Adventure Time spin-off follows the gender-swapped versions of Finn and Jake — Fionna and Cake. After first appearing in a episode of Adventure Time’s third season, they appeared in four additional episodes and quickly became fan favorites. This is the third series in the Adventure Time franchise, following Adventure Time and the limited series Distant Lands. Madeleine Martin and Roz Ryan return to voice Fionna and Cake.

Harley Quinn season 4

One of television’s raunchiest comedies, we last saw Harley Quinn going out with a bang in the extremely horned-up “A Very Problematic Valentine’s Day Special.” Now Harley, Ivy, Clayface, and the rest of the gang return for more zany antics. Previous showrunners Justin Halpern and Patrick Schumacker are working on the spin-off Kite Man: Hell Yeah, so writer and producer Sarah Peters is taking over showrunning duties starting with this season.

Project K

With less American studios attending this year’s event, Kalki 2898 A.D. broke through as the first Indian movie ever to be presented at SDCC’s Hall H. It’s also the most expensive Indian movie ever made, breaking RRR’s previous mark, and the trailer shows off the big budget sci-fi world and a cast of superstars.

The Marvels

Carol Danvers, Nick Fury, Kamala Khan, Monica Rambeau, and Goose the cat are back in this sequel to Captain Marvel. In this trailer we got a glimpse at the movie’s villain, and how the respective Marvels end up connected through their light powers. From The Candyman remake director Nia DaCosta, The Marvels is slated for a November 10 release.

Teenage Mutant Ninja Turtles: Mutant Mayhem

The new Teenage Mutant Ninja Turtles movie from Seth Rogen and the team behind The Mitchells vs. the Machines comes out in early August, and the latest clip gets across the tone in the movie’s writing and animation. In this clip, we see Jackie Chan’s Splinter as the turtles try to sneak out to a movie.

Tiny Toons Looniversity

Want to feel old? The Tiny Toons are going to college.

A reboot of Tiny Toons Adventures, Looniversity follows their zany adventures at Acme Looniversity, and will premiere this fall on Cartoon Network and Max.

Gen V trailer

This spin-off of The Boys follows younger aspiring heroes at a college for superheroes. It’ll be set at the same time as the fourth season of The Boys, and is expected to release in September. The cast includes Jaz Sinclair (The Chilling Adventures of Sabrina), Chance Perdomo (also Sabrina), Shelley Conn (Bridgerton), Arnold Schwarzenegger’s son Patrick, and The Boys cast members Jessie T. Usher, Jensen Ackles, Colby Minifie, and P.J. Byrne.

Invincible S2 trailer

Robert Kirkman and showrunner Simon Racioppa’s adaptation of Kirkman’s comic returns for a second season after the explosive finish to the first. Steven Yeun, Sandra Oh, and J.K. Simmons are back as Invincible and his troubled parents. Considering the shenanigans the show got into in its first season, expect many more colorful guest stars and gruesome deaths.

Rick and Morty: The Anime

After experimenting with two shorts, “Rick and Morty vs. Genocider” and “Summer Meets God (Rick Meets Evil), Tower of God director Takashi Sano is back with a full-length season of Rick and Morty anime. Animation for the series will be handled by Telecom Animation Film (Shenmue the Animation, Tower of God), and much like Rick and Morty season 7, won’t involve creator/voice-over artist Justin Roiland.

Star Trek: Discovery season 5 trailer

It’s a good time to be a Star Trek fan, with plenty of new shows airing new seasons nearly year-round. This will be the final season of Discovery, bringing the adventures of Captain Michael Burnham (Sonequa Martin-Green) and her crew to a close. Star Trek legend Jonathan Frakes is back — as a director — and Battlestar Galactica’s Callum Keith Rennie joins the growing cast, which now also includes David Cronenberg.
