The Electric-type Gym is located near the south-west of Vermilion City. After acquiring the Chop Down secret technique from the Captain of the S.S. Anne, you can slice the skinny tree blocking the entrance. Inside, there’s a puzzle that you must solve to challenge the Gym Leader.
Now, you may have noticed the red and blue-coloured bins. Those are actually red herrings (uh, is one of them a blue herring?). The bins you actually want are the middle bin along the top row, followed by the bin directly below it, in that exact order. Check those two bins in the right order and the electric fence will vanish.
If you’re smart, you can actually reach the two bins without battling any trainers. To do so, we recommend going around from the right side, then approach the first bin from the top or sides. Next, without going below the first bin, position yourself so you’re standing to the right of it.
Then go down towards the Sailor below, but don’t speak to him obviously. While standing above him, inspect the second bin from its right. That way, you won’t be seen by the trainer towards the left, who’s looking your way. But you may want to battle the trainers anyway for the experience and for the glory!
From bottom to top:
By now, you’ve probably seen your fair share of Magnemite. Thanks to its Steel-type, it takes a heavy 4x damage from Ground-types. You could probably shake the ground near it and it’d faint. Fire and Fighting-types are also good.
Honestly, it can’t get much simpler than this. Well, actually, the first Voltorb can use Self-Destruct, which can deal some hefty damage. It’s fast too, so don’t be surprised if it uses it. The second one isn’t so bad.
This Pikachu doesn’t have any Electric-type attacks for some reason, but it can use Thunder Wave to cause paralysis. So you should still use a Ground-type if possible.
