The Day of Black Sun (1): The Invasion was a perfect and very entertaining episode of Avatar The Last Airbender. I really enjoyed watching this episode because it was the first part of the invasion of the Fire Nation. I thought the Fire Nations Gate's of Azula were pretty cool. I enjoyed seeing Sokka's new invention which was ingenious! It was also cool to see some familiar faces that have come to help. Zuko has been fighting himself internally for some time now, and it seems he has made a decision, but as to what exactly is left unknown for now. I look forward to watching the second half of the invasion of the Fire Nation!!!!!!!
