Hydreigon is a powerful Dark and Dragon type Pokémon. It's a great Pokémon to add to your roster, especially in Pokémon Go. Capturing the unique creature is a lot more complicated than just acquiring it. Hydreigon is the final evolution of Deino, so you have to start with the first form before you get the third and final form of Hydreigon.
You have the chance to meet Deino in the wild and capture him in 10 kilometer eggs. For those who are fully invested in trying to catch this Pokemon, you might want to empty all your incubators and start throwing all your 10 kilometer eggs there. Because he's a Dark and Dragon type, you have a chance to meet him at night, in movie theaters, in cities, and on golf courses. When you locate Deino in a particular location, try to find a PokéStop nearby to use a decoy, and try to catch more.
You need 25 Deino Candy to transform him into Zweilous, then 100 Candy to evolve him into Hydreigon. He has a max CP of 3, offense of 625, defense of 256, and stamina of 188. He has an incredible attack power threshold, but he's slightly lacking in defense, so you might not want to. use it as your first option in a battle.
For those who are considering using Hydreigon against other trainers, you want it to know Dragon's Breath, Dark Pulse, and Dragon's Pulse. He can learn gun flash, but given the alternatives, you'd better forgo that as a suitable option. When you face Pokémon in raids or in gyms, you want it to know the Dark Bite and Pulse, Dragon's Breath and Dark Pulse, or Dragon's Breath and Dragon's Pulse. Dragon's Breath and Dark Pulse might be the more appealing option as they cover two different types.
When it comes to adding a Hydreigon to your collection, it's all about taking the time to be patient and keep looking for them. If you know you can't locate a Deino in your town, try acquiring 10-kilometer eggs from PokéStops to make sure you still have a chance to capture it.
