While I'm not a huge fan of the character design of the Chitauri for the Avengers movie, the figure is a pretty good representation of a scaled version of this design in action figure form. If the price is right and you're trying to collect the Avengers line of figures, then I think it's most definitely worth getting.
What's the problem with most action figure lines today? Plenty of heroes but no one to fight. Well this guy gives you a great start to an alien invasion that could cripple the world without the help of the avengers.
