InPokemon GO, the game brings new Seasons and events on a timely basis as part of the live-service format it tends to follow, many of which include new or recurring Raid Bosses. Raids are a way for Trainers to go up against powerful Pokemon in battle to defeat them for rewards and XP, or even capture a specimen to add to their Pokedex, upon successful defeat. There are quite a variety of different Raids available with 1 - 4-Star Raids featuring basic forms and evolved forms of Pokemon often or sometimes found in the wild, while 5-Star Raids are reserved for Mythical and Legendary species, Shadow Raids involve Shadow Pokemon, and Mega Raids are a chance to battle against Mega Evolutions.
As more significant Raids such as 5-Star, Mega, and Shadow Raids involve some of the most powerful Pokemon specimens in the game, it is important that Trainers take the time to prepare for them in advance, offering themselves the best chance at success. Duringthe Dual Destiny Season, both the Attack Forme and Defense Forme of Deoxys are available in 5-star Raids, meaning plenty of Trainers will be making the most of this opportunity and seeking them out. To help them effectively prepare for battles against these bosses, a guide referencing the key weaknesses and resistances, as well as best counters, has been included below.

Pokemon GO: Deoxys Attack Forme / Deoxys Defense Forme Weaknesses & Resistances
InPokemon GO, both the Defense and Attack Formes of Deoxys are purePsychic Type monsters, meaning they have relatively straightforward weaknesses and resistances to keep in mind when going up against one in battle. Deoxys is resistant to Pokemon and moves of theFighting and Psychic Types, so Trainers should avoid utilizing such monsters so as to not put themselves at any disadvantage in battle.
In contrast to those resistances, Deoxys also has three core weaknesses:Dark Types, Ghost Types, and Bug Types- so players should instead prioritize building a team that utilizes strong Pokemon and moves of these same attributes. Lastly, players may want to keep in mind that due tothe Weather Boost mechanic, Deoxys will receive a boost in power when fighting in Windy Weather, so Trainers may want to avoid Deoxys Raids under such circumstances, if possible.

Pokemon GO: Best Counters For Deoxys Attack Forme & Deoxys Defense Forme
InPokemon GO, the best way to take down Deoxys' Defense Forme or Attack Forme is by utilizing a team of suitable counters. These counters should target Deoxys' core weaknesses through their Type or powerful moveset combinations, whilst also having decent enough stats to withstand hits from Deoxys and out-damage or outlive it in battle.STAB - Same Type Attack Bonusmay come in handy for such battles, as this mechanic introduces additional damage dealt when a Pokemon’s Type and the Type of the move it uses are the same.
