You will arrive in Vermillion city after from Olivine. Lt. Surge, the electric gym leader, is here.
Go to the gym in Vermillion City in Kanto and battle Lt. Surge, the Gym Leader. He'll give you the 9th Gym Badge after you defeat him.
you'll get lt surge phone number at the power plant but put pikachu in your team first
After going to Luciva city in Pokemon Dark Cry, a person must fight the gym leader, Surge. Dark Cry is a non-official Pokemon game.
LT. Surge has a level 28 Raichu and that's it.
The electric type gym leader in Pokemon heartgold and soulsilver is lt. surge of vermilion city, kanto, who uses a lvl. 51 raichu, two lvl. 47 electrodes, a lvl. 53 electabuzz and a lvl. 47 magneton.
To fight Lt. Surge, you need to find the two keys. Look around in the little containers. If you find one key/whatever, the other one should be right next to it. You need two items to get to Lt. Surge. I made it through this gym without battling the trainers.
He is in Vermilon city
talk to the trainers and lt surge
To trade Pokemon with gym leaders, you must find them around the cities. Some will be standing in random cities at random times looking for trades. Lt. Surge, for instance, awaits at the magnet train in Saffron City.
Lt. Surge can be found outside the Power Plant in the Kanto region every day between 9 AM and 12 PM which is the time in which you can interact with him in order to get his number registered in your Pokégear however you can only find him outside the Power Plant after you have captured the Legendary Pokémon that is known as Zapdos.
After you've beaten all the previous gym leaders(Brock, Misty, Lt. Surge, and Koga), and have obtained the tea from celadon, you can fight Sabrina, whose gym is in Saffron. Your Pokemon should be lv.'s 40+.
