Despite being the weakest Avengers Movie, the Age of Ultron Pop line was actually really good.
You have some fantastic Marvel Pops here, such as the blast-off Iron Man, The classic Hulk and one of the best Captain America Pops here.
Also the Avengers Age of Ultron Funko Pop collection feature some great characters which don’t have many Pops at all. For example, Scarlet Witch, Hawkeye and Vision only have 2 variants in the whole of the Marvel Funko Pop collection (edit: Hawkeye has received much love from the Avengers End Game wave).
Plus the Age of Ultron Pop list has possibly the best Black Widow Pop of all – at least in my opinion of course!
