So, it's been debated a few times that Bleez's wings may or may not be constructs. Not extensively, because I care about Bleez more than any other living human, apparently. I am here, however, to prove that....
First off, here is Bleez. Little bitty fluffy Bleez, with her feathery angel wings.
Those are, essentially, "bird wings". Agree? Well then.
This is what the skeleton of a bird's wing looks like:
None of these examples, however, are what Bleez's skeletal wings look like:
These wings are clearly skeletal bat wings, meaning they are of her own design. Meaning that she created them.
"But Bleez can't make constructs!" you exclaim.
Yes she can.
"I'm still not convinced! I irrationally believe that those are still her natural wings!"
I rest my case.
