Even since Robert Downey Jr. suited up Tony Stark and became Iron Man, the Marvel character has never proved more popular. Part of his allure is the fact that he's an inventor at heart, with his Iron Man suits being the crowning glory. The suits have also gone through many different iterations, and Stark has a number of them to fit specific scenarios, as we saw in the final battle of 2013's Iron-Man 3. 

But how many Iron Man suits does Tony Stark in fact have? It's one of those questions that has plagued the mind of many a geek, and one that Marvel aims to answer with Stark Week fast approaching (10-17 August). 

To this end, Marvel has begun a YouTube series chronicling each and every Iron Man suit ever made, regardless of the media it has appeared in. The first of this animated series appeared on Marvel's YouTube channel earlier this week, with the grey Mark I, classic yellow and red, as well as War Machine being detailed.
