you have to beat Candice at her gym then team galactic will smash a hole in it to get to spear pillar
There's no such thing as "team team galactic". If you think you can join Team Galactic, you can't. The only Game where you play as a semi-bad guy is Colosseum.
Team Galactic's Boss' name is Cyrus.
the team galactic boss gives it to you at the team galactic hideout!
you cant you have to beat sunnyshore's gym
You will need Galactic key and this how to get Galactic key you will need to talk to a Galactic team mate by the Galactic HQ.
Team Galactic as a whole last sees you in the Veilstone Headquarters but the last time any Team Galactic personnel is seen is in Stark Mountain.
