Sword & Shield 1v1 has been a change of pace from previous generations of 1v1. The removal of Mega Evolutions and Z-Moves wildly changed common strategies and meta threats, and freed up itemslots for most of the metagame. In addition, a generational mechanic banned for the first time, and a large range of Pokemon were also actively removed from the metagame starting out, and even more challenging was that many of these Pokemon were reintroduced in massive bursts with not just one, but two DLC drops. As such, SS 1v1 as a tier went through several key phases, with several Pokemon excelling in some but falling flat in others. This makes the evaluation process for the tier's Top 10 titans a very unique experience compared to previous iterations of this project.
With the unique nature of Gen 8 1v1 put on the table, there's clearly quite a bit to discuss, and a shocking range of Pokemon that could be feasibly nominated here. The big question that we will try to answer with this thread is, which of all the Pokemon were the 10 most influential throughout the entirety of Gen 8?
From July 31st to August 13th, you will nominate Pokemon that will be voted on for the top 10 most influential Pokemon throughout Gen 8. After that, you will all evaluate all the nominations and individually rank the Pokemon from 1-10 by vote. Of course, all the nominations will count as long as they're reasonable and fit the criteria. Please keep in mind that we're not ranking Pokemon based on how good they are, but we're ranking Pokemon based on how influential they've been. When nominating Pokemon, consider their influence not just in the current Crown Tundra format, but in the Isle of Armor, Home, and Pre-Home metagames as well (if they were there, of course)!
Please use the format below to frame your posts or we won't count them!

:ss/pokemon:
What effect did this Pokemon have on the metagame?
Explain how the Pokemon effected the metagame as whole, and how the metagame adapted around it. A brief description of which Pokemon it countered and which Pokemon it did well against would be good here as well. Be sure to consider their impact in previous iterations of SS 1v1 as well if they weren't removed.
How was this Pokemon used?
Explain what sets the Pokemon ran frequently, and how it differentiated itself from its competition. Additionally, feel free to elaborate on how it broke past its traditional answers with unique sets.
What caused it to have a significant impact?
What exactly made this Pokemon have such a large impact on the metagame? Was it its stats, ability, useful resistances, amazing synergy, or the ability to sweep most of the metagame very easily? Did a certain Pokemon cause it to become that much better when it was partnered with it?
How do/did you deal with this Pokemon in 1v1?
What are the best checks/counters to this Pokemon? How does the metagame adapt to this Pokemon?

What effect did this Pokemon have on the metagame?
Aron proved itself as a menace in almost all eras of SS 1v1, and is well deserving of its slot in the Top Ten Titans. It heavily warped the meta, forcing the usage of Mold Breaker Haxorus, Urshifu-Rapid-Strike, or a Ghost-type on any remotely competitive team, and single-handedly ruining the viability of opponents which could not take it down, like Darmanitan-Galar.
How was this Pokemon used?
Aron frequently lowered its level, and then equipped Endeavor, Spiky Shield, Sandstorm, and Toxic with a Berry Juice. This enabled it to lower the opponents HP to the single digits with Endeavor, heal back to full, and chip down its opponent with one of the other three moves. Its incredible ability in Sturdy guaranteed that it would survive two turns, giving it plenty of time to take out the opponent. Additionally, Choice Band overwhelmed opponents who weren't ready to take physical attacks, like Blissey.
What caused it to have a significant impact?
An incredible combination of movepool, typing, and ability blessed Aron. Sturdy and Endeavor let it lower opponents HP easily and safely, while three different options to chip down opponents in Spiky Shield, Sandstorm, and Toxic let it finish off a variety of opponents. Additionally, its Rock / Steel typing gave it an immunity to Sandstorm and Toxic, letting it pull off its strategy on opponents like Tyranitar.
How do/did you deal with this Pokemon in 1v1?
Many opponents relied on multihit moves, such as Surging Strikes, to break through Aron. Additionally, Ghost-types, which could not be damaged by Endeavor, served as a fairly consistent counter. Finally, other methods of breaking through Sturdy such as Necrozma's Photon Geyser and Mold Breaker Haxorus were adopted to deal with Aron.
You're allowed to reserve nominations, but make sure to finish them in 24 hours, or they will be back up for grabs! Also, you can only reserve one nomination at a time. This is to make sure that your reservation gets done before you finish another. If you pick a Pokemon that has more than one form, be sure to clarify which it is.
