Birds are the Light Side and the Rebel Alliance, pigs are the Dark Side and the Empire. As such, Darth Vader is a pig-equivalent. Behold the trailer:
At 31 seconds in, the gameplay footage clearly demonstrates Darth Vader's pig-itude.
Additionally, at 23 seconds in, this adorable "unboxing" video of Hasbro's Angry Birds Star Wars toys shows the packaging labels Darth Vader as "Darth Vader Pig":
Moreover, the game only includes levels that feature:
- Tatooine
- The first Death Star encounter
- Hoth (eventually via a free update)
- Dagobah (via in-app purchase)
Meaning it stops around halfway though the plot to The Empire Strikes Back. If there is an eventual redemption for the Darth Vader pig or a twist ending regarding his true nature, it's not in this game, or at the very least, not in this game yet.
You should only ask practical, answerable questions based on actual problems that you face.– Matthew Read Nov 8 '12 at 21:42If your question generally covers things such as... Plot and characters in games …then you are in the right place to ask your question!If this is not a question about plot/character, feel free to close/delete it. – mmdanziger Nov 8 '12 at 21:45
