"Details" opens Mega Gengar's per-move damage against that boss, its breakpoints and its energy cycle — the same drawer the boss page opens.

22 more placings not shown.

Mega Gengar places nowhere with Shadow, Mega and Legendary attackers hidden, so the table above is the everything-on ranking. With everything switched on it places on 37 bosses (best #4 vs Mew). Points follow pokebattler.com's published rule — 5 for a first place, 4 for a second, 3 for a fourth, 2 for an eighth, 1 for a sixteenth, weighted 10x at Tier 5 / Mega, 4x at Tier 3 and 0x at Tier 1. Level 40, 15/15/15, no weather, no friendship, no dodging. Snapshot generated 2026-10-08.

Type matchups

Every one of the 18 attacking types against this typing. GO multipliers: 1.6x super effective, 0.625x resisted, 0.390625x doubly resisted.

  • Weak (4)
  • Neutral (8)
  • Resists (5)
  • Double resists (1)

Every tile and chip is a link: it opens the Pokedex filtered to that type, so a weakness leads straight to the attackers that exploit it. Pokebattler lists only the weaknesses; the eleven types that do neither matter as much to a raider deciding what to bring, so all 18 are shown with the exact multiplier.

Same typing, same matchups

Released ghost / poison forms with the highest attack — they share every weakness and resistance above.
