Lightningrod forces all single-target Electric-type moves used by foes to target the Pokémon with this Ability. Electric-type moves used by foes will never miss the Pokémon with this Ability, unless it is in the semi-invulnerable turn of a move such as Dig or Fly (Thunder will never miss it if it is in the semi-invulnerable turn of Fly or Bounce).
If another Pokémon becomes the center of attention, Electric-type moves will be directed to it instead of the Pokémon with Lightningrod.
Lightningrod now also forces all single-target Electric-type moves used by allies to target the Pokémon with this Ability. Electric-type moves used by allies will now never miss the Pokémon with this Ability, unless it is in the semi-invulnerable turn of a move such as Dig or Fly (Thunder will never miss a Pokémon in the semi-invulnerable turn of Fly or Bounce).
Along with its previous effects, Lightning Rod also gives the Pokémon immunity to all Electric-type moves, and raises the Pokémon's Special Attack by one stage whenever it is hit by an Electric-type move. Electric-type multi-strike moves (such as multi-strike moves affected by Electrify or Electric-type moves affected by Parental Bond) will only activate this effect once. If the Pokémon is protected from the move or immune to the move due to being Ground-type, its Special Attack will not increase.
If a Pokémon with Lightning Rod is holding a Cell Battery, Lightning Rod absorbs the move, so the Cell Battery's effect is not triggered.
In Triple Battles, Lightning Rod cannot redirect Electric-type moves if the Pokémon is out of range.
Generation VII onward
Even if the Pokémon would be immune to the move due to being Ground-type, Lightning Rod activates and boosts the Pokémon's Special Attack.
Outside of battle
In Pokémon Emerald, Trainers registered with the PokéNav's Match Call function will call twice as often if a Pokémon with Lightningrod is in the first place in the party (even if fainted).
In Pokémon Sword and Shield, if a Pokémon with Lightning Rod is in the first place in the party, there is a 50% chance the game will force an encounter with an Electric-type Pokémon, if one is possible. It shares this effect with Static.
A Pokémon with Lightning Rod draws in all Electric-type attacks used within the same room without taking any damage, and since Gates to Infinity also increases the Pokémon's Special Attack. Unlike the main series, Lightning Rod also attracts multi-target Electric-type attacks.
Dungeon enemies that have the Ability Lightning Rod can also negate the Lightning Rod of the player's team member(s).
Draws Electric-type moves from nearby foes, absorbs them, and raises Special Attack.* The Electric-type moves of enemies in the room are drawn to the Pokémon and absorbed, which also raises its Special Attack!*
When Togedemaru's opponent uses an Electric attack, the attack changes direction and hits Togedemaru instead, who takes no damage from that attack. Togedemaru can then use the absorbed electricity to power up its own Electric-type moves.
In Riddle Me This, Pikachu is able to defeat Blaine's Rhydon by aiming its electric attack at the Rhydon's horn, with it being stated that the horn acts as a lightning rod, apparently allowing Pikachu to overcome Rhydon's normal immunity to Electric attacks. However, in Generations III and IV, it didn't affect type immunity at all, and nullifies Electric damage in Generations V and on.
