Heatran and Garchomp were the last remaining members of the Old Gen OU crew after Skarmory and Tyranitar fell in Gen 8. As for the other older members of OU, Keldeo fell in Gen 8, Breloom fell in Gen 7, Excadrill fell in Gen 8, Gengar fell in Gen 7, Gyarados fell in Gen 6, Hydreigon fell in Gen 7, Jirachi fell in Gen 8, Lati@s fell in Gen 7, Magnezone fell in Gen 8, Mamoswine fell in Gen 7, and Salamence fell in Gen 7. If you count Dragonite regaining OU status in Gen 4, it's the longest serving member of OU other than Lando.
Anyways, Ferrothorn is going to be the last man standing.
