This guide will let you know how to find & defeat team GO Rocket Leaders in Pokémon GO.
You will need equipment named Super Rocket Radar to locate the Team Go Rocket leaders.
You have to defeat six members of Team Rocket, and you will get one piece of the radar after defeating each of them. Then combine all six parts to make a Super Rocket Radar.
Team rocket leaders are primarily located in the maps with daytime. So teleport yourself there and then use the radar to find their location.
You can defeat only one team leader using the radar and collect the radar parts again to locate and defeat the next one. You must have space in your bag to collect the radar parts.
It is quite difficult to defeat team leaders as they are very powerful and smart. Try to use different pokemon to defeat them.
