How to Solo Mega Garchomp in Pokémon GO: Mega Mewtwo Y Strategy Guide

Soloing a Mega Raid in Pokémon GO is the ultimate test of a trainer’s dedication, resource management, and mechanical skill. Mega Garchomp, a powerhouse Dragon and Ground-type boss, is a formidable hurdle for any solo player. While the community often relies on Ice-type attackers to exploit Garchomp’s double weakness to Ice, the raw, unadulterated power of Mega Mewtwo Y offers an alternative, high-skill path to victory.

This guide breaks down the precise requirements, strategies, and execution needed to take down Mega Garchomp solo using the sheer force of Mega Mewtwo Y.

The Mathematical Reality of Soloing Mega Garchomp

To solo a Mega Raid, you are fighting two distinct battles: the raid timer (300 seconds) and the boss's HP pool. Mega Garchomp is a "Tier 4" equivalent in terms of raid difficulty, meaning it has a massive health pool that demands high Damage Per Second (DPS).

Mega Mewtwo Y is chosen for this task due to its staggering Base Attack stat—the highest of any Psychic-type in the game. By using Mega Mewtwo Y, you aren't just relying on type-advantage; you are relying on "neutral" DPS that is so high it outpaces many super-effective options. However, because you are not hitting for 2x super-effective damage (like an Ice-type would), your margin for error is razor-thin. Every missed second of attacking is a step toward a "Time Up" screen.

Preparing Your Mega Mewtwo Y for Peak Performance

You cannot walk into a Mega Garchomp raid with a standard-issue Mewtwo. To stand a chance at a solo victory, your Mewtwo must be optimized to the absolute limit.

1. Leveling and IVs

Your Mewtwo should be at Level 50. The difference in stats between Level 40 and Level 50 is significant enough to alter the outcome of a solo raid. Aim for a 15/15/15 (hundo) or as close as possible, with a focus on the Attack IV.

2. The Mandatory Moveset

Fast Move: Confusion. While Psycho Cut generates energy faster, Confusion provides the raw damage output necessary to burn through Garchomp’s health.
Charged Move: Psystrike. This is non-negotiable. Psystrike is widely considered one of the best moves in Pokémon GO. It has a high damage-to-energy ratio, allowing you to cycle through your energy bar efficiently.
Legacy Requirement: You will likely need an Elite Charged TM to secure Psystrike if you haven't already. Do not attempt this raid with Psychic or Shadow Ball; the DPS drop is too steep to clear the clock.

Mastering the Mechanics: Dodging and Re-lobbying

When soloing, "fainting" is your enemy. Every time your team wipes, you lose roughly 10–15 seconds to the re-lobby animation. This is time you cannot afford to lose.

The Art of the Dodge

You must learn the "dodge rhythm." Mega Garchomp’s charged moves (such as Earth Power or Outrage) have distinct visual tells. Watch the boss's model closely. When the boss performs its charged move animation, swipe to the side.

Why dodge? A successful dodge reduces damage taken by 75%. This allows your Mega Mewtwo Y to survive 2–3 additional cycles of Psystrike, which translates to thousands of points of extra damage.
When not to dodge: If you are hovering at the 30-second mark and the boss is at 5% HP, stop dodging. Prioritize raw damage output to finish the fight before the timer expires.

Team Composition for the Cleanup Phase

Even a perfect Mega Mewtwo Y will eventually faint against the relentless pressure of a Mega Raid boss. Your team must be structured to maximize the "Mega Boost."

Slot 1: Mega Mewtwo Y. This is your primary damage dealer.
Slots 2–6: High-DPS support. If your Mega Mewtwo Y faints, you need high-tier attackers to finish the job. Because your Mega Mewtwo Y provided a psychic damage boost while on the field, consider running other high-level Psychic types like Shadow Mewtwo or Gardevoir (which also deals Fairy damage to pressure Garchomp’s Dragon typing).

Pro Tip: If your Mewtwo faints, don't waste time selecting a new team. Use a pre-made "Raid Party" that you’ve saved specifically for this encounter. The game will prompt you to rejoin, and if your party is pre-set, you can be back in the fight in under five seconds.

Don't ignore the variables that can swing a close raid in your favor:

Weather Boost: Look for Windy weather. This boosts Psychic-type moves by 20%. This is the single biggest "cheat code" for this solo attempt. If it is Windy, your DPS output increases to a level where the solo becomes significantly more achievable.
Friendship Bonuses: Even if you are soloing, raiding with a "Best Friend" present (even if they are just sitting in the lobby or not attacking) provides an attack bonus to your Pokémon. If you have a friend who can join the raid and then immediately back out, you gain the "Friendship Damage Bonus" for the duration of the encounter.

Common Mistakes to Avoid

Over-dodging: Some players dodge every single fast move. This is a trap. You lose too much attack time. Only dodge the high-damage charged moves.
Ignoring the Clock: If you reach the halfway point of the raid timer and the boss has more than 50% HP remaining, you are likely failing the DPS check. In this scenario, it is better to quit, revive your team, and try again rather than wasting the full 300 seconds.
Low-Level Counters: Do not fill your remaining team slots with "recommended" Pokémon. The game often recommends high-HP, low-damage tanks. You need pure glass-cannon DPS.

Conclusion: Is the Solo Worth It?

Soloing Mega Garchomp with Mega Mewtwo Y is an exercise in extreme optimization. It is not an efficient way to farm Mega Energy, as it requires massive resource investment in Mega energy, Candy XL, and Elite TMs. However, as a skill-based challenge, it represents the pinnacle of solo PvE content in Pokémon GO.

If you succeed, you have effectively mastered the core mechanics of the game. If you fail, use the raid log to analyze where your DPS fell short and adjust your team accordingly. Remember: in Pokémon GO, the meta is always shifting, but high-level preparation and mechanical mastery remain the keys to success.
