Extinct Matteo is one of the rarest Secret Brainrots in Steal a Brainrot, and for many players, it's a flex item as much as it is a generator. It was only available during the Extinct Event, and because of that limited-time window, very few players managed to obtain it. If you've ever seen someone place one, you'll notice it instantly—it has a look and vibe that stands out from most other brainrots.
This guide covers what makes Extinct Matteo special, how players originally got it, its value in today's economy, and a bit of trivia worth knowing if you're aiming to complete the Extinct set.

Extinct Matteo has a rugged, explorer-like design that fits the event's archaeology theme. He wears a big black hat, a full brown beard, and a black eyepatch, giving him a mysterious, old-world adventurer look. His outfit resembles worn explorer clothing with a brown coat and pants, and pieces of white bone-like textures are visible across the body, suggesting he has been through some harsh survival or excavation conditions. The overall appearance feels like someone who's been digging through ruins for decades and came back with stories—and scars.
It's definitely one of the most visually memorable brainrots in the game.

Extinct Matteo's limited availability means many players still look for alternative ways to complete their collections. If you ever decide to buy brainrots online from U4GM, just make sure to compare values and trade safely so you don't overpay for something that's already rare.
Because it is a Secret rarity, spawned only during a limited event, and had a very low appearance rate, Extinct Matteo is considered one of the highest-value collectors' Brainrots in the game.
Factors affecting its value:
Overall, Extinct Matteo's value is driven more by prestige and collection importance than pure income per second.
Extinct Matteo is one of three exclusive Brainrots that could spawn during the Extinct Event:
These three can be given to Archaeologist Sammy to spawn La Extinct Grande, a powerful special result.
Out of the three, Extinct Matteo is the rarest, making him the hardest part of the ritual set.
Because many players couldn't get him, he is often considered the main bottleneck for unlocking La Extinct Grande.
Extinct Matteo is one of the most sought-after Brainrots in Steal a Brainrot. With its Secret rarity, limited availability, and unique role in summoning La Extinct Grande, it's both valuable and iconic. Even though its income rate is not the highest, its collection importance and rarity make it a must-have for dedicated players.
If you ever see someone with one, they either have great luck—or they were there grinding during the event.
