Basculegion looks average on paper at 530 BST. But Adaptability is why it sees play — build around that and it pulls its weight. A-Tier tank on our tier list.

What is Basculegion weak to?

Basculegion's biggest threats include Manectric (Electric), Roserade (Grass), and Aegislash (Ghost), all carrying super-effective STAB moves. Dark-type attackers are also a problem.

How do you evolve Basculegion?

Basculin evolves into Basculegion through a special method. Basculegion is the fully evolved form. At 530 BST, it's got solid stats to work with.

What is the best ability for Basculegion?

Basculegion gets Adaptability, Swift Swim, and Mold Breaker. But Adaptability is the one that matters — it's the centerpiece of every viable set. Build around that.

What role does Basculegion play in battle?

Basculegion is a physical attacker with base 112 Attack. Enough bulk to take a hit or two, too. But the speed tells the real story — base 78 Speed is workable — faster than some, slower than many. Fits the tank role.

What games is Basculegion in?

Basculegion can be found in Scarlet & Violet and Legends: Arceus.

Free switch-ins on Normal and Fighting moves make Basculegion useful in any team that needs that coverage. Adaptability boosts same-type moves from 1.5x to 2x damage. It needs some investment to avoid getting outsped. Known as the Big Fish Pokemon.

The stat line revolves around HP. Percentage recovery gets extra mileage here. Attack backs it up, though Defense doesn't pull its weight. Worth 3 HP EVs on a medium-fast 1M XP curve to max out.

Prediction matters here. Choice Scarf means Basculegion can't change moves after clicking, but the payoff is speed patching through item lock. Max Attack and Speed EVs with Adaptability back that up. The remaining moves prevents free switches.

Most of Basculegion's flexibility comes from TMs. Same-type output runs through Wave Crash and Hydro Pump, but Normal and Dark and the rest of the TM pool push it from predictable to genuinely threatening.
