Wasn't too sure which Forum to use, but I figured there might be more of an impact here in Imperial Assault land.
I was looking at some DK Star Wars Rogue One books, one of them was a visual guide to the movie (contained some photos of the shooting of the film as well as the bits and pieces in the film); in the book we saw the home that Jyn Erso had when she was a child, and then the book did a break down of her toys and the names she gave them.
Mr. Stormie was the storm trooper; she had some wooden hand made toys of a Star Destroyer, Light Cruiser and a Clone Wars jedi cruiser.
One of her 'toys' in her possession was a tall lanky metallic droid she called Mr. Iggy. Looked a lot like IG-88 series. Could her Dad have built these droids? Imagine having a special action/ability: 'IG-Series immunity: No IG model of Assassin droid can target you for an attack if there was another target on the board.'
Of interest or not?
