Dialga Meta-Analysis

Being able to see Dialga after its stat rework and 9% nerf is certainly disheartening. While it may have the resistances of Steel typing to make it somewhat prominent, the lack of a good move pool and the nerf really drop it from its expected usage.

Now seeing what Dialga has, it is almost as bad as it could have been. Draco Meteor is somewhat serviceable, being comparable to Outrage, but being worse on the aspect of a single bar charge move that opens up chances for lost energy. Meanwhile, Dragon Breath is a straight out nerf, it is worse than Dragon Tail in every way, so the ‘mons with Dragon Tail have a default leg up on the Time God. Palkia with Dragon Tail and Draco Meteor, as well as Garchomp with the glorious Dragon Tail and Outrage it has, will almost certainly do better.

Meanwhile, its Steel usage is pretty nice, to be honest. As predicted, it has the high energy gain Metal Claw, as well as the nice Iron Head to make for a decent charge move. This will easily place it among the top Steel types. However, it will not be the best, as Metagross with Meteor Mash eclipses Dialga.

Finally, it needs to be said that the Steel typing in combination with Dragon of Dialga makes is a resistant powerhouse. It is only weak to two types, Fighting and Ground, while boasting 10 resistances, with 2 double resistances to Grass and Poison, as well as being a Dragon not weak to Dragon. While this does open up Dialga to get smashed by Groudon and Machamp armies in a raid, it also allows it in gym battling to be almost unrivaled, boasting huge power and a wide number of resistances to tackle any potential gym defender. Not to mention it is a Dragon that is not weak to dragons, making it extremely viable in raids.

That being said, a Tl;Dr for this day can be that unless they decide to change Dialga around, this Legendary Dragon is going to play second fiddle due to bad Dragon moves and Metagross getting Meteor Mash.

Weather Influences:

The biggest weather to look out for is Windy and Snow weather where Dialga as a raid boss gets boosted, while also looking to fight one in either Sunny or Cloudy where Groudon and Machamp will walk all over it.

Dialga
WEAKNESS Fighting Ground	BOOSTED BY Windy Snow
Supreme Counter Machamp Counter Fighting Dynamic Punch Fighting It is a fact of life for Pokémon GO, if something is weak to fighting, Machamp will rear its head and go out swinging, boasting the highest neutral weather time to win over any other available counter to Dialga, save Breloom against non-Steel movesets. Excellent Counters Breloom Counter Fighting Dynamic Punch Fighting Breloom is a glass cannon and should be kept to the lead slots in the fight. In any case, where Dialga does not have Steel moves, it will have a faster time to win than even Machamp at the cost of more faints. Hariyama Counter Fighting Dynamic Punch Fighting Fat Machamp is never far behind, with a very similar time to win compared to Machamp and Breloom, with usually fewer deaths than either counter. Lucario Counter Fighting Close Combat Fighting For those lucky enough to hatch Riolu and get it up to a high-level Lucario, this is your time to show off. Lucario has managed to fit in around Blaziken’s spot in the fighting meta, with this being a scenario where it improves on the fire chicken due to its resistance to both Dragon and Steel Heracross Counter Fighting Close Combat Fighting Toxicroak Counter Fighting Dynamic Punch Fighting Groudon Mud Shot Ground Earthquake Ground Groudon’s usefulness cannot be understated here, in fact, Groudon actually has as high, if not higher, times to win against Dialga when the weather is Sunny, and even placing in the top 6 when it isn’t, all while fainting significantly less than any other counter. Groudon is very worthwhile to use against Dialga. Good Counters Time to win rises considerably from here, and these Pokémon are best kept to B-teams or used when a large group is active. Like almost any boss, it sometimes comes to strong generalists like Rayquaza and Salamence, although this becomes dangerous if it has a dragon moveset.

Shiny Dialga

Shiny Dialga will most likely not be available at launch, but it is reasonable to assume it will be in the game at some point. Basically, Shiny Dialga just gets a little more green-tinted all over.
