Galactic emperor is the final boss you verse.He'll throw tons of attacks like when he fires ice cubes at you and uses AA turrets shaped like cats,so dont use a jet.Use Proto eagle in your team,he can thow out some damage at him. NEVER use a dragon/tank they wont work on him cause he will just fire a lasor and your gonna die. Try using either G-red/Neo G-Red and a victory king/baron.They can give some damage if you put them in the right order.
