What This Matchup Means
This selection has 3 damaging type weaknesses and 7 defensive resistances or immunities. Prioritize any 4x weakness first because both defending types amplify that attack.
Type effectiveness is the foundation of the matchup, but abilities, stats, moves, items, and battle format can change the best decision. Check whether the rest of your team can safely switch into the attack types listed as weaknesses above.

Pokemon Type Calculator FAQ
How does the Pokemon type calculator handle dual types?
It multiplies the effectiveness against both defending types. Two weaknesses create 4x damage, while a weakness and resistance cancel to 1x damage.
Why does a Pokemon have a 4x weakness?
A 4x weakness occurs when the same attacking type is super effective against both of the Pokemon's defending types.
Do abilities change Pokemon type weaknesses?
Some abilities add immunities or reduce damage from particular types. This calculator shows the standard type chart, so ability-specific effects should be checked separately.
Can I check weaknesses for a complete Pokemon team?
Yes. The Pokemon team calculator analyzes up to six team members and highlights repeated weaknesses, resistances, immunities, and defensive coverage gaps.
