Galar
Solrock (Pokemon Ruby)
Lunatone (Pokemon Sapphire)
This pair of defensive Pokemon (who happen to share an evolutionary line!) have never finished a generation below UU. Even more interestingly, they never exist in the same tier at the same time (one is always OU while the other is UU, or vice versa)

Liquidation
Spikes
Golisopod (SM UU)
Sparkling Aria
Sparkling Aria was originally exclusive to Primarina (Gen 7) but was later also given to Lapras via Breeding (Gen 8)
Pokemon regions tend to be based on real-world locations! This region goes one further, and actually shares the same name as the place it is based on!
Kanto (based on the Kanto region of Japan)
Sawk (Pokemon X)
Throh (Pokemon Y)
These twins from Hoenn finished every generation in the same tier until Gen 7, when one of them was banned from the tier the other finished in.
Latios & Latias (Ubers Gen 3 and 4, OU Gens 5 and 6)
Latios finished Gen 7 in UUBL while Latias finished UU (Megas were also different)
Note that Latias is now legal in DPP OU but it finished the generation in Ubers.

Hoenn
Magmar (Pokemon Green)
Electabuzz (Pokemon Red)
This pair of Legendary Pokemon from the same generation completely dominated the Ubers tier during Generations 6 and 7 (as well as VGC 2016 and VGC 2019). Before that point, only one of the two in the pair were actually relevant in either Ubers or VGC.
Primal Kyogre & Primal Groudon
Rapid Spin
Drain Punch
Mach Punch
Throat Chop
Hitmonchan (SS PU)

Sinnoh
Oranguru (Pokemon Moon)
Passimian (Pokemon Sun)
It's not common for a Pokemon to stay OU forever. These two Kanto classics gave it their best shot. One a Ghost type, the other a Water type, these two stayed OU together until they finally fell to UU in Gen 7.
Gengar & Starmie
Boomburst
Heat Wave
U-turn
Sleep Talk
Swellow (XY NU)
Powder

Every year (except 2020 because Covid LUL) a new VGC World Champion is crowned at the World Championship along with the 6 Pokemon they used to win it all. Which region has the most representation amongst Champion teams?
Unova (16 out of 70 World Champion Pokemon came from Unova)
If you care, 15 / 70 come from Hoenn and 14 / 70 come from Sinnoh. The rest come from everywhere else kekW
Gothita / Gothorita / Gothitelle (Pokemon Black)
(You don't need to guess the entire evolutionary line)
Solosis / Duosion / Reuniclus (Pokemon White)
In Gen 7 UU, these two Pokemon were the ultimate glue of the tier. Both were considered nearly required to check or counter the other. (Hint: both Pokemon have mega evolutions, but only one of the two in the pair was actually a Mega in UU)
Mega Altaria & Scizor
