Comic Con Revolution 2027
May 22 – May 23, 2027 Ontario Convention Center, Ontario…

Somewhere in the artist alley there is a table with your favorite book on it, and the person who drew it is sitting behind it, waiting for someone to say the right thing. That is the whole reason to go. The Inland Empire's comic weekend stays small enough that you can actually reach that table — no wristband lottery, no line that eats your morning, no security walking the queue with a clipboard. Panels run all day for the people who want to hear how the work actually gets made. The exclusive merchandise moves early, which the regulars know, which is why they walk the floor before they do anything else. Pop culture at large is here too, but comics are still the spine of it. Ontario Convention Center, in Ontario. Bring the friend who has been quietly drawing in the margins since middle school and has never shown anyone.

West Coast Card Show — TCG Edition Ontario 2026
May 28 – May 31, 2026 Ontario Convention Center, 2000 E …

Pokemon, One Piece TCG, Magic: The Gathering, and sports cards all in the same building for four days. The West Coast Card Show TCG Edition at the Ontario Convention Center brings live grading services, influencer appearances, competitive tournaments, and a vendor hall drawing sellers from across the West Coast. The Ontario edition is distinct from the larger Anaheim show - it has a sharper TCG identity and a more competition-focused energy. If you are hunting specific singles, looking to grade a collection, or want to compete in open-bracket formats across multiple card games in a single weekend, this is the show that makes the trip worthwhile. The Ontario Convention Center is easy to reach from across the 909, LA, and the South Bay. Free-to-attend areas are available throughout the show floor, and competitive registration varies by game and bracket. Most of these vendors and graders work the Anaheim edition and the rest of the circuit too, so the stranger you end up elbow to elbow with over a quarter bin is someone you will see again three shows from now.

Comic Con Revolution Ontario 2026
May 16 – May 17, 2026 $20-35 2000 E Convention Center Way, Onta…

At the big conventions you queue for a photo. At this one you sit down across from the person who drew the thing, and they have time. The floor is built around direct creator access — meet artists and writers face to face, commission original work while you wait, pick up independent titles shelved next to the mainstream publishers, and dig through a dealer room genuinely packed with back issues, figures and collectibles. Cosplay runs the whole weekend without anyone treating it as a competition. Saturday draws the bigger crowd. Sunday moves slower, which is when the browsing gets good and the conversations get longer. Ontario Convention Center, 2000 E Convention Center Way — off the 10 and the 60, parking on-site. Weekend passes are the better value if you are coming both days. Bring cash and a list. You will leave with something signed by a person whose name you now know.

Comic Con Revolution
May 18, 2024 Ontario Convention Center, 2000 E …

The Inland Empire does not usually get things like this, which is exactly why people drive in from across the region and treat a Saturday in Ontario like a holiday. A comic convention out here is not a scaled-down version of the big one down the freeway. It is the one where you can actually reach the artist tables, actually get a question in at a panel, actually stand in front of a guest long enough to say the thing you rehearsed in the car. The floor is walkable. The lines end. Nobody is fighting you for a badge, and nobody is too cool to talk about the run they have been collecting since middle school. Exhibitor booths, panels, special guests, and a full day of it at the Ontario Convention Center on Convention Center Way. Bring the kid who is just old enough to start having favorites. This is where a person finds out their thing has other people in it.
