Aerodactyl

The lead metagame in SS Ubers is quite a crucial factor, with few prominent Magic Bounce users and limited opportunities to remove entry hazards due to the tier's fast-paced nature. However, Stealth Rock's effectiveness is hindered this generation due to the introduction of Heavy-Duty Boots and its frequent use by Ho-Oh and Yveltal. Spikes is a far superior choice due to bulky threats such as Groudon, Eternatus, and Zygarde taking minimal damage from Stealth Rock. Regardless, Aerodactyl stands out from other hazard setters due to its high Speed stat and decent Attack, threatening other leads such as Galvantula, Froslass, and the aforementioned Ho-Oh and Yveltal. Aerodactyl also outspeeds most multi-hit move users, bar Triple Axel Pheromosa, that would otherwise break its Focus Sash before it has the chance to even set up Stealth Rock. With these decent traits, Aerodactyl manages to carve a solid niche as the fastest Stealth Rock Lead in Ubers.
