Toughest Gym Leader

[ThousandDragon]

Mine were Bugsy and Whitney!
Bugsy because I chose chikorita as my partner and her Scyther was a massive pain.
Whitney because Stomp, Milk Drink and it's high Def.
I manged to beat Bugsy with Unknown while spamming potions and Whitney because of Elekid I go of the Pokewalker.

[Snigeln]

For me it must have been Pryce.
When i came to his gym i realized i didn´t have a single super effective move against ice. Ended up in starting to level a larvitar who later became part of my main team.

[Gen_Hen]

Blue, the only guy who really use some tactics not just brute force.

Clair is tough but that is only because her pokemons are powerful.

[Kutie Pie]

If it's not Whitney, then it was Blue. Trick Room really threw me off, I had to level-grind for a bit before facing him again.

[Arcanine724]

Definitely Whitney! Her Miltank's attract got me angry and when I couldn't attack, and she used stomp. Grrrrrrrrrrrrrr!

[Elysian]

I had a hard time beating Lt. Surge this time...

[Shadow♠]

Sabrina, she's the only one I actually lost to iirc. I didn't level up my team enough.

[G50]

Whitney was the toughest Gym Leader for me. Her Miltank always gives me trouble in these ganes. During my Cyndaquil runthrough however, Clair really gave me problems.

A lovely tie between Clair and Whitney

[Dawn and Piplup]

If Red doesn't count then Claire. Piplup vs .... Hard battle. Difficult battle.

[Blazethehaze6]

Depending on your team, Chuck, Claire, or both

[Cremia]

Anybody who doesn't say Whitney is wrong! hehe (:

But Clair was also a challenge too :P

[Cloud_Arcanine]

Whitney. Used my male Quilava, not good when Miltank uses the combination of attract and rollout, followed by having thick fat as an ability *facepalm*

[Sietse23]

Whitney
10char.

[Elisa]

Toughest for me was Jasmine. Whitney is just plain annoying.

[fasola91]

When I was younger Whitney. I hated her and Milktank, but this time it was Clair because I didn't have anyone on my team good against her. I just went and got a Poliswine and killed her.

[Meowth City]

I didn't find any of the gym leaders particularly hard to beat. In the past, Clair was always the toughest for me. However, since my Feraligatr knew Ice Fang in SS, it was a breeze for once.

[Qmaz246]

Clair was the toughest of them all, but after that it was whitney for a close second. She catches all that are off guard and can think they can win with their starter pokemon.

[G50]

Clair was also really difficult, her Dragon types can be a pain with Cyndaquill or Totodile as the starter.

[JustifiedTerrakion]

Probably the hardest gym for me is Whitney.Her Miltank is stupidly powerful with it's Milk Drink and Stomp.I hate Miltank.
