Dialga

Using Dialga in a Playthrough

Dialga is a single-stage Steel/Dragon Legendary with an exceptional 680 base stat total, combining base 150 Special Attack, 120 Attack, 120 Defense, and 100 HP with one of the most useful defensive typings in the series. In Generation IV, Steel/Dragon gives it a Poison immunity, numerous resistances, neutrality to Ice and Dragon despite being a Dragon-type, and only Fighting and Ground weaknesses; later generations remove Steel's old Ghost and Dark resistances but add Fairy resistance, which cancels Dragon's Fairy weakness into neutrality. Dragon Pulse, Flash Cannon, Earth Power, Aura Sphere, Thunderbolt or Thunder, Draco Meteor, and Stealth Rock make special or utility sets easy to build, while its base 120 Attack also supports physical or mixed coverage. Roar of Time is spectacularly powerful but normally forces Dialga to recharge on the following turn, making a safer Dragon move preferable whenever the extra power is unnecessary. Origin Forme, accessed through the Adamant Crystal in modern games, shifts 20 points from Attack into Special Defense while retaining base 150 Special Attack and 90 Speed, making it an even stronger special tank; Modest, Calm, or Quiet can all be useful depending on whether the player emphasizes offense, special durability, or Trick Room.

Dialga in Competitive Pokémon

Dialga was a foundational DPP Ubers Pokemon because Steel/Dragon typing, nine resistances plus a Poison immunity in that generation, excellent 100/120/100 bulk, and base 150 Special Attack allowed it to perform offensive and defensive jobs that few other Dragons could combine. Smogon documented support sets using Stealth Rock, Roar, Thunder, Earth Power, and Dragon STAB, mixed wallbreakers using Draco Meteor with physical coverage, Choice sets, Bulk Up, and even Trick Room variants that deliberately exploited Dialga's relatively modest base 90 Speed for an Uber. Unlike most Dragon-types, Dialga was not weak to Dragon or Ice in Generation IV, making it much easier to use as a defensive pivot against the tier's many powerful Dragons while still threatening them offensively. It has remained an Uber across subsequent generations, although increasing power creep and the loss of Steel's Ghost and Dark resistances reduced some of its old defensive dominance. Origin Forme introduces a different modern tradeoff by converting 20 Attack into Special Defense, producing a 100/120/120 defensive profile without sacrificing the 150 Special Attack that defines Dialga's best special sets, so contemporary use tends to favor its specialized special offense and utility rather than attempting to replicate every DPP role at once.

Dialga in Nuzlockes

If legendary Pokemon are permitted, Dialga is one of the safest offensive choices available because Steel/Dragon provides a huge resistance list, immunity to poison, excellent 100/120/100 bulk, and enough Special Attack to end many battles before repeated damage becomes relevant. Fighting and Ground are the main conventional weaknesses, and both are common coverage types, so Earthquake, Close Combat, Earth Power, and similar moves still need to be identified rather than assuming legendary bulk will absorb everything. Roar of Time is especially dangerous under permadeath rules because the forced recharge gives the opponent a guaranteed opportunity to act after the attack, while Draco Meteor's Special Attack drop can also create an awkward second turn if the target survives or another Pokemon immediately enters. Dragon Pulse, Flash Cannon, Earth Power, and Aura Sphere are generally safer when they already secure the knockout. Origin Forme further increases special durability by trading unused physical Attack for Special Defense, and Calm can reinforce that advantage, but many Nuzlocke rulesets exclude cover legendaries entirely, so its practical eligibility depends first on the player's rules.

Dialga is the legendary embodiment of time in Sinnoh mythology and is said to have hatched, along with Palkia and Giratina, from eggs created by Arceus at the beginning of existence. After the universe formed, Dialga withdrew into its own dimension, where time is described as flowing at different speeds and even in different directions; because it lives outside ordinary space-time, direct observation of its natural behavior is exceptionally difficult. Dialga can accelerate, slow, reverse, or completely stop time, travel between past, present, and future, and create or destroy an entire universe either independently or alongside Palkia. Legends say that time itself began moving when Dialga was born and continues to flow as long as its heart beats. The ancient Diamond Clan worshipped it as 'almighty Sinnoh,' mistakenly identifying Dialga with Arceus, and Dialga is capable of communicating telepathically through humans such as Adaman.
