As an Electric-type, Ampharos fills a straightforward role. Only weak to Ground. Known as the Light Pokémon. Introduced in Gen 2. Relies on priority moves or Scarf to keep up.
Sp. Atk and HP carry most of Ampharos's stat budget. Speed's the obvious dump stat. Tough to catch and yields 3 Sp. Atk EVs. Follows a 1.06M XP medium-slow curve.
When it gets dark, the light from its bright, shiny tail can be seen from far away on the ocean’s surface.
Ampharos Weakness
GoodGround-type moves hit Ampharos for super-effective damage. Few weaknesses and 3 resistances make the typing clean. With 90 HP and balanced defenses, Ampharos can afford to eat a neutral hit or two.
- Dark and Steel types added — Fairy does not exist yet
- Moves are Physical or Special based on type, not per move
- Special stat split into Sp.Atk and Sp.Def
End of the line. Ampharos caps a three-stage chain that started at Mareep. Breeding produces the base form, and eggs are average hatch time. Sp.Atk grew the most through evolution (+50 over Mareep), and Ampharos peaks at 510 total stats.
How to Evolve
Breed with Ampharos to get Mareep eggs easily using 66 partners from the Ground and Monster egg groups. Notable egg moves include Body Slam, Reflect, Safeguard and 3 more.
Start with flexible EVs EVs. A nature nature gives Ampharos the right balanced lean, Leftovers adds passive recovery each turn, and an ability works in the background. Thunderbolt is the main damage option.

Without breeding, Ampharos misses out on Body Slam and Reflect. That's 6 egg moves adding depth that the base kit lacks. STAB comes from Zap Cannon and Thunder, with Normal and Fighting coverage and more rounding things out.

Watch for Rhydon (Ground) when using Ampharos. They all hit it super-effectively with STAB. Only 1 weakness means fewer dedicated counters to worry about.
At base 55 Speed, it won't be moving first often. On offense, Ampharos is a special attacker with base 115 Sp. Atk. Defensively? Enough bulk to take a hit or two. Best used as a wallbreaker.
