I mean, we all know Dragalge and Sharpedo are buds, and people keep trying to make GligarPass a thing, but this little pinecone is Sharkeisha's real pal:
Forretress @ Leftovers
Ability: Sturdy
EVs: 252 HP / 252 Def / 4 SpD
Relaxed Nature
- Rapid Spin
- Spikes
- Volt Switch
- Gyro Ball
Mega-Pedo is one of the best sweepers available for hazard offense, as it's a triple threat - it revenge kills early game, it wallbreaks midgame and it straight up sweeps late game when the opposing team is softened up by entry hazards. Spikes in particular work well with the shark, allowing you to reliably 2HKO bulky Waters with Crunch. Forry offers more than just Spikes, though - Rapid Spin support is also essential for a good hazard offense team, and Forry can easily switch into bulky fairies like physically defensive Florges who give Sharkeisha trouble. That slow Volt Switch is also great, as it combines with Pedo's decent power pre-evo to revenge kill a lot of offensive threats.
It combines well with any Mega-Sharpedo set, but I'm particularly fond of using Jolly Mega-Sharpedo with Protect/Crunch/Waterfall/D-bond and a backup sweeper like Puff or Luke or Gatr on hazard offense.
