Pokemon GO: Max Monday - Dynamax Wailmer Max Battle Guide

In Pokemon GO, Max Monday is a weekly event involving Max Battles, a unique in-game battle type that revolves around local spots on your map known as Power Spots. Much like traditional Raid Battles, Max Battles feature oversized monsters that players can take on to earn various rewards, as well as an encounter and a chance to capture the featured Pokemon, so long as they emerge victorious from the battle.

The latest Max Monday to take place during the Delightful Days season features none other than the iconic Gen 3 Water Type, Wailmer. If you’re aiming to make the most of this opportunity and potentially even capture your own Dynamax Wailmer for your collection or battling purposes, this guide has you covered with all relevant information you’ll need to prepare, such as key weaknesses and resistances, and some of the best potential counters/choices for this battle.

Pokemon GO Dynamax Wailmer Max Monday Battle Guide

The Max Monday Wailmer event is available for players to participate in on July 14, 2025, specifically taking place in-game between 6 PM to 7 PM local time. During this event, every single Power Spot on the in-game map will be taken over by Dynamax Wailmer, enabling players to farm multiple encounters/battles with the boss if they’re looking to capture multiple copies or collect as many rewards as possible within this one-hour window.

Wailmer Weaknesses & Resistances

Wailmer is a pure Water Type monster in Pokemon GO, meaning it has fairly straightforward weaknesses and resistances to consider. Wailmer is resistant to Pokemon and moves of the Fire, Ice, Steel, and Water Types. Players will want to avoid using such specimens during these Max Battles, and instead focus on utilizing Pokemon that have a Typing or powerful moves of the Electric and/or Grass Types, as these are Wailmer’s key weaknesses.

Dynamax Wailmer Counters

Players will want to consider Wailmer’s key weaknesses when selecting Pokemon to bring into Max Battles. However, Trainers also have more restrictions than the average Raid Battle, as Max Battles can only utilize Dynamax Pokemon. Regardless, there are still a few options that present themselves as most viable for this matchup, based on the previous Dynamax releases for the game.

Dynamax Bulbasaur/Ivysaur/Venusaur
Dynamax Grookey/Thwackey/Rillaboom
Dynamax Toxtricity
Dynamax Zapdos
Dynamax Raikou

Can Dynamax Wailmer Be Shiny in Pokemon GO?

In Pokemon GO, Shiny Wailmer already exists in its regular variant. This means that yes, Shiny Dynamax Wailmer will be available for players to obtain during the Max Monday Wailmer event, and in other future instances in which Dynamax Wailmer can be encountered.

If players want a shot at encountering shiny Dynamax Wailmer, they will need to take part in and complete multiple Wailmer Max Battles. After defeating the Wailmer, players will get a chance to capture the boss, and it is at this time that lucky Trainers may meet the shiny odds and encounter the shiny variant of this monster. However, there is no guarantee that you will encounter one, as shiny Pokemon are generally a rare occurrence in Pokemon GO.

If you’re unable to encounter a shiny Dynamax Wailmer through battles, trading is another possible option to consider. However, you will be restricted to connecting with other nearby players who already have the shiny, as Global Trades are not a thing in Pokemon GO. Online communities for the game, such as the various Subreddits available, are a decent place to search for and find trusted traders and other local players for these purposes.
