You are getting just the two outfits as pictured.  The bear is not included, nor are any other accessories.

This lot includes two Build-A-Bear Workshop outfits, featuring the iconic Dark Knight and Bumblebee Transformer designs. These yellow jumpsuits are perfect for any fan of the franchise, and are sure to make your bear stand out in any collection. The clothing style is a combination of costume and classic, making it versatile for any occasion.

The set includes both outfits, perfect for expanding your bear's wardrobe. The clothing type is specifically designed for Build-A-Bear bears, ensuring a perfect fit. The lot is being sold as-is, and would make a great addition to any collection.

You are also getting the red cap/hat/mask. It's the same size as a Build a Bear hat but can't find any information on it.  Looks a little like an Iron Man hat, but doesn't match ant pictures I've found.
