In MLB The Show 26, quirks are special abilities that give players unique boosts in certain situations. 

Diamond Dynasty

In Diamond Dynasty, quirks are tied directly to the player cards.

• Active Quirks: These are in-game boosts like Dead Red, which increases exit velocity on fastballs, or Outlier, letting pitchers throw over 101 mph.
• How to Get Them: You can't add quirks to a card yourself. The only way to get them is by acquiring cards that already have them—through packs, the Community Market, or special Programs.
• Top Players: High-rated stars like Aaron Judge can come with as many as ten quirks, making them really powerful on the field.

If you want to quickly build a top-tier Diamond Dynasty team loaded with powerful quirks, the fastest way is to focus on acquiring the right cards—high-rated stars like Aaron Judge already come packed with multiple quirks, giving you huge in-game advantages. For those who want to save time grinding, you can rely on trusted sources like SHANNENG to buy MLB 26 Stubs online, letting you unlock the cards and quirks you need without the wait.

Road to the Show (RTTS)

For your created player, quirks work a little differently—they show up more like perks.

• Passive Quirks: Your player can unlock descriptive quirks like Bomber or Sniper automatically when attributes hit certain thresholds (like 80+ Power for Bomber).
• College Rewards: Picking certain colleges in the RTTS path can give you one-time perks, like a boost to your power.
• Equipment & Perks: You can also manually improve performance by equipping perks and gear in your loadout—diamond-tier gear or perks like Clear for Takeoff can increase exit velocity.

Franchise Mode

In Franchise Mode, quirks are mostly fixed.

• Natural Development: Most generated prospects won't develop active quirks like Outlier over time. Players who start with quirks keep them, but there's no manual way to add new ones.
• Workarounds: Some gamers tweak prospect ratings to try triggering passive quirks based on high attributes, but this isn't an official feature and results vary.

Full List of All 19 Available Quirks

There are 19 Active Quirks in MLB The Show 26, each providing situational boosts that can significantly impact gameplay. Unlike standard passive quirks (like "Bomber"), these active versions grant tangible attribute bonuses during specific conditions.
