Trainer Tips

Shellos is a Water-type Pokemon with a stat total of 391. With its bulk spread of 105 Defense and 183 Stamina, Shellos has solid survivability in battles.

Watch out for Electric, Grass-type moves when using Shellos. These types deal super effective damage that can cut into Shellos's performance.

Shellos's moves get a damage boost in Rainy weather. Take advantage of weather conditions to maximize your DPS in raids and gym battles.

Unlocking a second charged move costs 50,000 Stardust and 50 Candy. With 3 charged moves available, a second move gives Shellos much better coverage in PvP battles.

Verdict

Collector's Pick
Shellos is a Water-type Pokemon with base stats of 103/105/183 (Atk/Def/Sta) and a max CP of 1,284. While it doesn't currently rank among the top raid attackers or PvP contenders, every Pokemon has its place in a trainer's collection. Shellos may shine during specific events, in limited-format cups, or when new moves are added in future updates. For now, hold onto a good IV specimen but save your Stardust and Candy for more impactful investments unless you're a dedicated fan of this Pokemon.

Frequently Asked Questions

What is the best moveset for Shellos in Pokemon GO?
Shellos has multiple viable movesets depending on the battle format. The ideal moveset varies based on whether you are using Shellos for raids, gym battles, or PvP — check the moves section above for a full breakdown of each move's DPS, energy cost, and coverage.
What are Shellos's weaknesses in Pokemon GO?
Shellos is weak to Electric, Grass-type moves. On the other hand, Shellos resists Fire, Ice, Steel, Water-type attacks, so avoid using those types against it. To counter Shellos effectively in raids and gyms, build a team using its weakest type matchups and pick attackers that have STAB moves of those types.
What is Shellos's max CP in Pokemon GO?
Shellos's maximum CP is 1,284 at level 50 (with XL Candy), or 1,136 at level 40. Reaching level 50 requires XL Candy, which is only available to trainers level 31 and above — earning XL Candy involves catching, hatching, transferring, and walking Pokemon. Shellos's CP is calculated from its base stats: 103 Attack, 105 Defense, and 183 Stamina. Powering up from level 40 to 50 requires a significant investment of XL Candy and Stardust, so plan your resources carefully. A 100% IV Shellos caught from raids or eggs (level 20) will have 649 CP, or 811 CP with weather boost (level 25).
What CP is a 100% IV Shellos?
A perfect 15/15/15 IV Shellos has the following CP at key levels: 486 CP at level 15 (research encounters), 649 CP at level 20 (raid and egg catches), 811 CP at level 25 (weather-boosted raids), and 1,284 CP at level 50 fully powered up. If you catch a perfect IV Shellos, it is worth investing Stardust and Candy to power it up, especially if Shellos ranks well in raids or PvP. A 100% IV (also called a "hundo") is the rarest IV combination, so tag and favorite it to make sure you don't accidentally transfer it.
How to get Shellos in Pokemon GO?
Shellos can be found in the wild, though it may be rare depending on your biome and current events. Shellos can also be obtained through trading with other trainers.
Can Shellos be shiny in Pokemon GO?
Shiny Shellos's availability depends on whether Niantic has released its shiny form. Not all Pokemon have their shiny forms available yet. Check the current events page and Community Day announcements for any updates on shiny Shellos availability and boosted shiny rates during special events.
