I cant defeat hannah please help I cant beat her 9 months (please use simple english because I dont know english so much :D)

you can use google translate :

 

you can beat her first pokemon with whatever way then use lightning rod ability seaking to sweep the rest

 

seaking, ability: Lightning Rod, nature: modest

iv: only require spatk iv 26+, the rest is doesn't matter

moveset: surf, ice beam, rain dance, agility

holding item: mystic water (can be bought in johto azalea town shop for 2k)

 

her second pokemon will use thunder punch to your seaking

but lightning rod seaking is immune to electric move

and seaking's spatk would raise for 1 stage

keep using agility to wait for spatk raising 6 stages

then use rain dance when the spatk is max

sweep with surf unless the opponent is weak to ice move

 

ps. you can use electric move to test the goldeen whether it's lightning rod or not

it helps saving money for poke balls

lightning rod seaking is good to beat some other bosses too

I used Flygon with dragondance , dragon claw, earthquake, crunch as moveset, leftovers as item,

 

use dragon dance 2x then use full restore, then dragon dance, if houndoom raises his sp atk, before you get 3 off just die and restart.

 

then use earthquake on everyone except talon flame (use cruch or dragonclaw) talon will take 2 hits, everything else with die in 1 hit except the mega sharpedo, he had about 1/10 of his heathbar so change to a pokemon with suckerpunch type move to finish I used archanine extreme speed
