Hello community! AUGHBAR here: frequent lurker, first time poster. I tried my hand at one of the categories that didn't have a record yet, and this is what I managed to come up with.
That's a 28 win streak in the Battle Factory (PLATINUM, Open level, Doubles). Lost to these.
804 | Rhydon | Adamant | Quick Claw | Earthquake | Stone Edge | Megahorn | Horn Drill | HP/Atk
945 | Registeel | Adamant | Shell Bell | Iron Head | Hammer Arm | Earthquake | Curse | HP/Def/SpD
The team I had was subpar consisting of Articuno, Flygon, and Floatzel.
Flygon used EQ, taking Rhydon to < 50% and Registeel to ~60%. Rhydon then OHKOs Articuno with Stone Edge. How did Rhydon outspeed Articuno you ask? I used Avalanche -.- worst play ever. Registeel used curse.
In comes Floatzel, who promptly gets OHKOed by a quick claw'd stone edge. Flygon KO's Rhydon with EQ and knocks Registeel to < 20%. Registeel then crits Flygon with Hammer Arm and that's the end of the streak! I didn't get to see the third pokemon since Flygon fainted the same turn it knocked out Rhydon.
