What to Prioritise
Mega Gyarados is the star of this raid event, and it's a solid option for your team. With its Water/Dark typing, it offers unique resistances and a powerful offensive presence. Focus on gathering a strong party of Electric and Fairy-type Pokémon to counter Mega Gyarados effectively. Pokémon like Zekrom, Raikou, and Togekiss can turn the tide in your favor. Remember to stock up on Revives and Potions, as you'll want to maximize your chances of taking it down efficiently.
Bonuses Worth Using
This event doesn't feature specific bonuses, so you'll need to rely on your typical raid strategies. Use a Lure Module or a Star Piece right before you engage to maximize your catch potential post-battle. Prepare for a chance at a shiny Mega Gyarados; with two shiny forms available, this is one of the more exciting aspects of the event. If you’re lucky enough to snag one, you'll want to power it up for both raids and PvP battles.
Is It Worth Your Time?
Engaging in these Mega Raids is worth it for the potential shiny catch and to strengthen your roster with a solid Pokémon. Mega Gyarados can be a valuable addition for both raids and GO Battle League, especially against certain meta threats. If you're a competitive player looking to expand your team, this is an event to participate in. However, if you're not particularly invested in Mega Gyarados or its shiny form, consider if your time might be better spent elsewhere in the game.
