Do fallen angels lose their wings?

Yes and no. They wings may shrivel and fall off. Or the wings may turn demonic and resemble bat wings. Do not hate bats because of this similarity.\

Answer

The term "Wings" when refering to angels is but a symbolic term. It sugests the power to move from one place to another. The bible talks about cherubims having wings but this only refers to the protection cherubims can give. It also says "I will bare thee up on eagles wings" Again sugestiing the power of movememnt from one place to another. I am sorry but angels do not have wings.
