X & Y Evolution
Partway through Deino's chain. Zweilous still has another evolution ahead before reaching Hydreigon. For breeding, takes forever to hatch with a decent partner pool via one egg group. HP has grown the most so far (+20), but there's still another 180 stats to gain in the final evolution. View every chain in the Evolution Chart.
How to Evolve
Breeding
Breed with Zweilous to get Deino eggs using 50 partners from the Dragon egg group. Notable egg moves include Assurance, Astonish, Dark Pulse and 7 more.
X & Y Zweilous Best Moveset
Hustle and Eviolite give Zweilous staying power beyond its evolution stage. Adamant nature boosts Attack, max Attack and Speed EVs set the spread, and the pre-evolution bulk actually works here.

Moves
The egg pool carries weight here. Assurance and Astonish aren't available any other way for Zweilous, and they meaningfully change what it threatens. Stack those on top of Draco Meteor and Outrage for solid options.

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 X & Y, 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.
