+1 252 Ribombee Hidden Power Ground vs. 252 HP / 188+ SpD Heatran: 232-276 (60.1 - 71.5%) -- guaranteed 2HKO after Leftovers recovery
+1 252 SpA Ribombee Hidden Power Fire vs. 248 HP / 200 SpD Scizor: 308-364 (89.7 - 106.1%) -- 37.5% chance to OHKO
Note that the Scizor set i listed lives a hit, but doesn't actually kill you back on a switch in, even without defense investment on the Ribombee.
