Stats & Training
Attack and HP carry most of Zweilous's stat budget. Speed's the obvious dump stat. Tough to catch and yields 2 Attack EVs. Follows a slow 1.25M XP grind.
The two heads do not get along at all. If you don’t give each head the same amount of attention, they’ll begin fighting out of jealousy.
The two heads have different likes and dislikes. Because the heads fight with each other, Zweilous gets stronger without needing to rely on others.
Zweilous Weakness
Type-wise, Zweilous takes extra damage from Fairy, Ice, Fighting, Bug, and Dragon. Watch out for Fairy attacks, those deal 4x damage. Psychic moves do nothing thanks to a full immunity. With 6 resistances, the defensive profile is strong.

Zweilous Guide
Zweilous is meant to evolve into Hydreigon. At 420 BST, the stats aren't there for competitive play yet. Pre-evolution Pokemon rarely hold up against fully evolved threats.
In Ultra Sun & Ultra Moon, Zweilous's biggest threats include Gardevoir (Fairy), Kyurem (Ice), and Machamp (Fighting), all carrying super-effective STAB moves. Gardevoir is the most dangerous since Fairy moves deal 4x damage. Bug and Dragon-type attackers are also a problem. With 5 weakness types, most competitive teams carry at least one counter.
Hustle is the go-to ability for Zweilous. It strengthens physical moves to inflict 1.5× damage, but decreases their accuracy to 0.8×. It's Zweilous's only ability.
At base 58 Speed, it won't be moving first often. On offense, Zweilous is a physical attacker with base 85 Attack. Defensively? Enough bulk to take a hit or two.
Game Availability
Zweilous joined the series in Black & White and has been available in 8 titles so far. With 6 generations of appearances, it's established itself despite the later start.
