Marvel Rivals knows how to keep things fun, even when the action gets intense. After dropping the Venom twerking emote, NetEase is back with another wild twist: A limited-time mode called Giant-Size Brain Blast. Here’s your complete guide to the upcoming Marvel Rivals Giant-Size Brain Blast mode that’s turning heroes into bobbleheads.
What Is Marvel Rivals Giant-Size Brain Blast?
Giant-Size Brain Blast is a new limited-time mode coming to Marvel Rivals on April 25th, 2025. As the name suggests, all heroes in this mode will have comically oversized heads. While the mode’s end date remains unknown, it’s sure to bring plenty of fun during its run.
This fun mode arrives as Marvel Rivals continues its Season 2, which recently introduced Vanguard Emma Frost to the roster. The upcoming 2.5 update will also bring Ultron to the game, expanding the character lineup even more.
Giant-Size Brain Blast Rewards
One of the biggest draws of participating in the Giant-Size Brain Blast mode is the exclusive rewards you can earn. These come in two main forms:
1. Title Rewards

At the end of each event round, players will receive title rewards based on their ranking with specific heroes:
Rank | Title Reward |
---|---|
Top 10 | Planet-Sized Brain (Hero Name) |
Top 100 | Monster-Sized Brain (Hero Name) |
Top 500 | Giant-Sized Brain (Hero Name) |
These titles will be a great way to show off your skills with your favorite heroes long after the event ends.
2. Brain Blast Emote

Perhaps the most exciting reward is the Brain Blast emote. By simply completing 10 matches in the Giant-Size Brain Blast mode, you’ll earn one permanent Brain Blast emote that can be used in standard Marvel Rivals games. The emote will allow your chosen hero’s head to temporarily balloon to a large size, even after the event is over.

How to Make the Most of Giant-Size Brain Blast Mode in Marvel Rivals
With the enlarged head hitboxes, certain heroes might have a natural advantage in this mode:
- Hit-scan Heroes: Characters like Hawkeye and Blak Widow are great at precision aiming. So with bigger heads, landing headshots will be easier for them.
- Spider-Man: His high mobility and larger target area could make him even stronger in this mode.
- Moon Knight: With easier headshot chances, his ranged attacks could hit harder.
- Venom: His aggressive play style could get even more dangerous with the bigger head targets.

Unlike past modes like Clone Rumble (which let teams use the same hero), Giant-Size Brain Blast doesn’t change the core gameplay. The big heads are just a fun visual twist, but they do make landing headshots easier. If you’re looking for a break from the stress of ranked matches or want to enjoy some silly fun, this mode is a great way to relax while still earning special rewards.
Will you be jumping into the big-headed action when Giant-Size Brain Blast launches? Log in to the game on April 25 when the first round kicks off, and don’t forget that you’ll need to complete 10 matches to secure your permanent Brain Blast emote!
