I understand that a lot of people look forward to my post and I hope you'll agree with me that the wait was worth it. My reputation is not always easy to sustain, people have high expectations of me and I want to live up to them. Decide for yourself and me if I lived up to my name. I am going to do this a bit differently this time to make this post more receptive and engaging. You'll figure it out : ) enjoy
This may come as a surprise to you since it's gone under the radar ever since it was introduced. Many of you might not even recognize this Pokemon(Dialga-Origin). A staggering 680 BST with good enough distribution for any tier. Dialga-O has great coverage and useful stab combination that allows it to hit fairies and blow up Pokemon who don't resist Dragon. If you can look past it's strengths, it has major flaws holding it back. As a certified doctor, I feel confident to diagnose this Pokemon with FMSS. Another major flaw, Dialga-O is item restricted., meaning it can't change it's item. Simialr to Ogerpon forms but it's item only boost it's stab moves by 1.2x. Dialga's main role would be a bulky offensive Stealth Rocker. Similar to Mega Tyranitar, Dialga hits very hard and is very tanky which allows him to trade well verses offensive Pokemon that'd normally threaten your defenisve core. Dragon Steel is generally a good typing if it's backed by strong offensive stats, it's not 4x weak to anything, it has a lot of great resist that all teams can appreciate and it's capable of living most unboosted neutral and x2 hits when it's healthy.
*technical difficulties*
These calcs are here for reference to help give you an idea how well it's stats hold up verse relevant meta pokemon.
Longevity? Hazards are the most improtant and easiest way to make progress in most 6v6 singles metagames. dialga-O not only lacks the ability to neutralize hazards by wearing boots or mitigating damage with leftovers, but it also has no reliable recovery to compensate for it's hazard weakness. It is worth noting that Dialga-O is immune to toxic which grants it one form of immunity to chip damage. This attribute doesn't make up for it's lack of recovery and hazard weakness, therefore I am giving it a C for longevity.
Unique Traits? Dialga has a bad ability due to the fact it's longevity is poor, generally you aren't going to be stalling pp as a wincon. It has a Generation1 movepool, no notable signatures. Flamethrower, Ice Beam, Thunderbolt, Stealth Rocks, Thunderwave, Toxic, Eartquake and Earthpower. However, it's move slots are limited due to Stealth Rock being mandatory, you're forced to sacrifice certain matchups based on what you pick. Ice Beam and Thunderbolt will most likely be dropped unless they're used over flash cannon which makes Draco Meteor less threatening against teams with Fairies. I am not doing + or - for these tiers, just S being the highest and D being the lowest. That being said, B for Unique traits.
Versatility? Dialga-O is not versatile at all. It doesn't have viable setup moves like Calm Mind or Nasty Plot and you can't run items on Dialga which removes Choice sets, Z moves out of the equation. I think it would be fairly effecient at what it does anyways so this isn't as critical as the other categories. This is easily it's worse trait, D tier.
Splashable? This section is more theoretical so it shouldn't be taken serious but a Pokemon's splashability contriubtes to it's viability greatly. I mentioned earlier that this Pokemon is comparable to Mega-Tyranitar without Pursuit. Melmetal is perhaps a better comparison (s/o xurk) with Stealth Rocks. All these Pokemon are very good at trading, primarily used on Bulky Offense and Balance. C tier for splashability.
MetaGamerGRRRR? This section is based off how well this Pokemon matches up verses the metagame. I think I speak for everyone that more Steel types ar always welcomed into the tier. Additional Tapu Lele checks and potentially more options for Balance outside of Ferrothorn is more important now than ever because of the recent suspect test results. Dialga-Origin is capable of checking Wellspring similarlly to Ferrothorn but trades Longevity (and Spikes) for a more aggressive Stealth Rocker. Dialga-Origin matches up well verse every Defogger and Rapid Spinner. It can get Stealth Rocks up for it's team and trade well into Great Tusk, Landorus, (Non Z-Fight Torn)Tornadus-Therian, Zapdos, Corviknight etc. I give it S for this section.
Compatible? The section focuses on overlapping slots and team synergy whereas splashability focuses on which types of teams Dialga-O fits on. Ex; rain, screens, balance, stall. It's never bad to have Stealth Rocks available, more often than I'd like to admit, I find myself trying overly compressing my Stealth Rockers with moves such as Toxic, Thunder Wave, Defog, Taunt and then most of the time thes Pokemon are locked into two slots already which makes it difficult to choose which move I want. Ex: Landorus Earthquake and U-Turn, Tornadus-T Hurricane and U-Turn + Knock or NP + Coverage. Many top tier Pokemon woud appreciate it's presence, freeing up moveslots for them and maintaining an important role on it's team. (S/O gamer but swag) Anonnymous person brought to my attention the potential for Dialga-O + Alomomola. If we look past the obvious, Dialga-O deals with some Pokemon that usually exploit Alomomola which consist of, Wellspring, Ursaluna and generally any strong breaker that Dialga-O can threaten by outspeeding or teraing to eliminate it. Dialga-O has earned another A for this section.
Longevity: C
Unique Traits: B
Versatility: D

Overall: B+
