Dread Our Coming, Suffer Our Presence, Embrace Our Glory (Solonavi War Cry)
The question is while using the Leader rules out of the TI3 Rules if you capture a enemy leader do you get the benefit from that leader.
No, you put captured leaders on your race sheet (or somewhere similar). You do not get any benefits of them, though you can execute them or give them to other players (including the owner). Note, though, if you have a captured leader, every time someone successfully invades one of your planets, there's a chance they may find one of your captured leaders and take it from you.
