BW OU
Kabutops is never going to be anywhere close to a top-tier threat in BW OU, but it does carve a niche as a counter-style option vs Rain that also has access to Rapid Spin. This is reminiscent of Sand Rush Excadrill on Rain teams when it was briefly allowed, which put sand teams in really difficult positions regarding the weather war. It goes without saying that Kabutops is nowhere near as good as Excadrill - its significantly weaker, its frailer and has less useful defensive typing, and it struggles against 2 common pieces against the archetype you want to counterstyle (Ferrothorn and Keldeo), but nonetheless it might be able to fit on some highly specialised sand, or DragMag teams in place of Starmie.

Beaten super hard by Ferrothorn so Magnezone support is near essential if you want any shot at actually beating rain. If you're already going Kabutops + Magnezone, you might as well go with DragMag and forego Starmie. From there, you have a decent rain match-up if you can get rid of Ferrothorn. Kabutops can spin in a few particular situations where Starmie can't, for example in the face of Scarf Keldeo or Latios in Rain, therefore removing rocks for something like Multiscale Dragonite. Against sand, Kabutops' lack of Pursuit weakness means it gets more longevity against Tyranitar. Its
very niche but might work if you're opponent is a known rain-lover. Rock Gem is needed if you want the clean OHKO on defensive Politoed, but Life Orb does the job with rocks up and is generally better. Breloom rain is tougher but +2 LO Kabutops in Rain does 86%+ to 252/0 Breloom, so its not insurmountable.

- Aqua Jet / Low Kick
This is a more balls to the wall approach. By dropping Rapid Spin, Kabutops can find room for Aqua Jet which makes it actually match-up decently vs some sand builds. Aqua Jet dissuades Landorus-T from revenge-killing, which can be an issue for those double ground, Tyranitar / Ferrothorn / Rotom-W / Landorus / Excadrill / Latios-type teams. Magic Guard sand teams are an issue, however, as doesn't consistently beat Reuniclus unless its Rock Gem
and Adamant (you need Jolly for standard Excadrill), and Sash Alakazam duh. Obviously still requires Magnezone support, unless you're willing to drop something for Low Kick.
Kabutops' biggest issues are:
1) Frail and prediction-heavy - Kabutops doesn't seem like it gets many safe opportunities to spin or SD, as its defensive typing and stats don't lend itself to generating safe turns vs the common rain teams. Every time you go for an SD or Rapid Spin has a risk attached to it, because unlike Starmie, Kabutops can't just spin in front of defensive waters and expect to survive the rain-boosted scald. Against sand, your best shot is HP Ice-locked Lando-T or Superpower/EQ-less Tyranitar, otherwise you're just praying they switch out.
2) 4MSS - you have to pick the defensive Pokemon that you're going to lose to. Kabutops can technically break through Ferrothorn with +2 LO Low Kick (116% minimum vs 252/0 ), but it can't really find the room for it. Dropping Stone Edge means you can't break Politoed or Tentacruel, and dropping Waterfall sucks vs everything. This basically necessitates Magnezone support, but because you actively
want rain to be up, you probably need to use Specs Magnezone rather than Sunny Day, which makes Zone easier to take advantage of. Any Kabutops set without Aqua Jet is limited to one KO at best before Landorus-T comes in, which is just not good enough for a frail Pokemon like Kabutops that rarely generates safe turns to SD already.
Something like this can work in theory if you want to counterstlye rain, but its slower and clunkier and Starmie is far away the better choice the vast majority of the time:
