In Pokémon GO, the primary goal for many players is to earn the daily allowance of 50 PokéCoins. To do this, you must place your Pokémon in a Gym and hope they stay there long enough to accumulate value (1 PokéCoin for every 10 minutes). However, with millions of trainers actively playing, holding a Gym is easier said than done.

If you place a weak Pokémon in a Gym, it will be defeated in minutes. To maximize your chances of lasting several hours—or even days—you need to understand the mechanics of "tankiness," type resistances, and motivation decay. In this guide, we will break down the best defenders for Gyms in Pokémon GO and the strategies you should use to keep your territory secure.

1. Blissey: The Undisputed Queen of Gym Defense

If you have spent any time playing Pokémon GO, you have likely seen a Blissey at the top of almost every Gym. There is a simple reason for this: Blissey has the highest HP stat in the entire game.

The "Time-Out" Strategy

In Gym battles, the attacker is fighting against a clock. Blissey’s massive health pool makes it a "Time-Out" defender. Even if an attacker has powerful Pokémon, it takes a significant amount of time to chip away at Blissey's health. Most attackers use Machamp or Lucario to deal super-effective damage, but even then, a high-level Blissey is a massive obstacle.

Best Move Set for Blissey

To make your Blissey even more annoying, ensure it has Zen Headbutt (Psychic) and Dazzling Gleam (Fairy). Both of these moves are super-effective against the Fighting-type Pokémon that players usually use to attack Blissey.

2. Chansey: The Low-Maintenance Strategy

You might wonder why you would use Chansey (Blissey's pre-evolution) when you could just use Blissey. The answer lies in the "Motivation Decay" mechanic.

Why Chansey is Better for Long-Term Defense

In Pokémon GO, Pokémon with higher CP (Combat Power) lose their motivation faster. A 3000+ CP Blissey will lose its motivation and become easy to defeat in just a few hours. A Chansey, which usually stays below 1200 CP, loses motivation much slower. This makes Chansey the perfect defender if you are placing a Pokémon in a rural area or a Gym you don't plan on visiting for several days.

3. Snorlax: The Versatile Tank

Snorlax is the classic defender. While it doesn't have as much HP as Blissey, it has higher attack stats, meaning it can actually hurt the attacker while it’s being hit.

Coverage with Body Slam

The best move for a defending Snorlax is Body Slam. It is a three-bar Charged Move, meaning Snorlax will use it very frequently. This forces the attacker to dodge constantly, slowing down their progress and making the battle much more tedious.

4. Togekiss: The Fighting-Type Punisher

Most people attack Gyms with Fighting types like Machamp, Hariyama, or Lucario because they are strong against Normal types (Blissey, Snorlax, Chansey). To protect your Gym, you need a "Fighting-type Counter," and Togekiss is the best in the business.

The Fairy/Flying Advantage

Togekiss is a Fairy/Flying type, which means it double-resists Fighting moves. If an attacker isn't paying attention and keeps their Machamp in against a Togekiss, their Machamp will be knocked out in seconds by Togekiss’s Charm fast move. Placing a Togekiss immediately after a Blissey in a Gym is the smartest way to drain an attacker's resources.

5. Metagross: The Steel-Type Powerhouse

Metagross is an excellent defender because it is a Steel/Psychic type, giving it a massive number of resistances. It is particularly good at stopping attackers who try to use Fairy or Ice types to clear a Gym.

The Threat of Meteor Mash

A Metagross with the Community Day move Meteor Mash is terrifying. It hits extremely hard and comes out quickly. Even if the attacker brings a Fire-type counter, Metagross can usually land one or two hits that significantly drain the attacker’s health.

6. Milotic: The Pure Bulk Choice

Milotic is a pure Water-type, which is a great defensive typing because it only has two weaknesses: Grass and Electric. Many players don't carry strong Grass or Electric attackers in their primary "Gym clearing" team.

Dragon Tail and Surf

By giving Milotic Dragon Tail, you can deal significant damage to Dragon-type attackers (like Dragonite or Rayquaza) that players often use as generalists. Combine this with Surf, and Milotic becomes a very consistent, high-health defender that requires effort to remove.

7. Understanding Motivation Decay: Why CP Isn't Everything

To be a master of Gym defense, you must understand how motivation works. When you place a Pokémon in a Gym, its CP will slowly drop over time. This is "Motivation Decay."

  • High CP (3000+): Loses about 10% of its max CP per hour. These are great for busy city centers where you only need to hold the Gym for an hour or two.
  • Low CP (Under 1500): Loses motivation much slower (around 1-2% per hour). These are best for holding Gyms overnight or in quiet parks.

If you want those 50 PokéCoins, sometimes placing a 1400 CP Wobbuffet is actually smarter than placing a 4000 CP Slaking.

8. Pro Strategy: The "Golden Razz Berry" and Pokémon Order

Even the best Pokémon will eventually fall if an attacker is persistent. Here are two pro tips to keep your Gym standing:

The Golden Razz Berry Trick

If you receive a notification that your Pokémon is "hungry" or "needs a treat," you can feed it a Golden Razz Berry remotely. This instantly restores its motivation to 100%. If an attacker has almost beaten your Blissey and you suddenly pop a Golden Razz, they have to start the entire process all over again. Most attackers will give up after one or two refills.

The Order of Placement

Gyms can hold six Pokémon. A well-organized Gym should alternate types to force the attacker to switch Pokémon constantly. The Perfect Sequence:

  1. Blissey (Normal - weak to Fighting)
  2. Togekiss (Fairy - strong against Fighting)
  3. Snorlax (Normal - weak to Fighting)
  4. Metagross (Steel - resists almost everything)
  5. Chansey (Normal - weak to Fighting)
  6. Milotic (Water - only weak to Grass/Electric)

Conclusion

Defending a Gym in Pokémon GO is about more than just picking your strongest Pokémon. It is about choosing defenders like Blissey and Chansey to waste the attacker's time, using Togekiss and Metagross to counter common attackers, and understanding the nuances of Motivation Decay.

By using the "Golden Razz Berry" strategy and coordinating the order of Pokémon with your teammates, you can ensure your Gym stays your color long enough to get those coveted daily PokéCoins. Remember, a good defense isn't just about power—it's about being too much of a hassle for the attacker to bother with!
