i think the hardest gym leader for me was the first gym leader(forgot her name)because i started with torchink i know it learns doubble kick at lvl 16 when it evolves but i acidently stopped the evoloution so that my story

They where all to easy to beat. I owned all of them and I didnt get hurt exept for brawly. hardest was brawly but he was stil easy.

Tate and Liza.....they are pretty tough unless you use surf or something like that

For me it is always Wattson because I never have any Pokemon that are strong against electric so I have to go catch one and raise it to a high enough level

To be honest the one I had the most trouble with was the first one (I er, don't remember the name offhand) and it's been like that in ALL the games for me. I have a tendancy to use the fire starters, so I always have trouble getting past the rock types in the first gyms. Nosepass really, really pissed me off.

wallace is hard...escpecially his milotic, but i found a good grass type can do the trick lol

the toughest gym leader for me was wionna as i had a lot of pokemon weak to flyers the rest were just pushovers

flannery becouse here torkoal that did know overhoat and 1 hitted me and and other Pokemon all time=\

I thought the twins were hardest!! i almost lost to them! i had like 1 pokemon left. i had 6. but i fought them a long time ago so i cant remeber acttacks or anything rly...

definitely TATE and LIZA

hardest for me it was winona cos her kept on usin dragon dance then aerial ace/earthquake on my , and !!

not sure probaly wallace

I chose Juan. He's tough . I can't seem to defeat him!

I chose jaun. i have a strong team of all dragons and Dragons reak against ice type. But My latios defeated him. And my salemance was a big help too!

none of them

The twins, Liza and Tate, were the hardest for me to defeat. They had a great strategy, and few of my attacks were super-effective against them. My Pokemon were ill-suited against theirs. They were also the only gym leaders that I lost against.

i think there all easy with the right pokemon

i think there all easy with the right pokemon

norman was the hardest for me, liza and tate always died against a sharpedo + anything combo

Tate & Liza...
I spended 3 days of training with my fellows
toi stand a chance and it was
really hard battle.

The only one problem i had when it came to gyms was Juan.not only is he stronger than wallace but his kingdra is more annoying than wallace's milotic.
just my opinion

for me it would have to be T&L. the combo of and is just amazing. will be the distraction while makes itself stronger and crushes you with one psychic attack in the end.

Tate & Liza. Their combos were powerful and well-timed. I had one hell of a time trying to beat them

I play Sapphire and there Norman was the hardest to defeat. I think it's because there is no story or trainers between Flannery and Norman, so you don't have a chance for lvling up your team.
