”不細工な皮で包み…" is this a metaphor?


So I'm reading part of a book, and one of the characters says this;

> 「不細工な皮で包みやがって」

When I tried to translate it and understand what it means, it didn't make too
much sense to me "Hiding behind ugly skin" (?) leading me to believe this may
be some sort of metaphor?

Context: character A is going towards B, about to launch an attack on him.
Character B is defending himself behind a barrier he built using the lifeforms
he created. I believe it is character A who then says the above line before
aiming to attack B in order to make his barrier disappear.




特にメタファーなどはないと思います。「a barrier he built using the lifeforms he
created」が実際どのくらい「不細工」なのかはわかりませんが、それを指して、侮蔑的に・さげすんで「不細工な皮」と言っていて、文字通り「不細工な皮で（自分を）包みやがって！」あるいは「不細工な皮に隠れやがって！」と言いつつ、「こんなもの剝いでやる！」「こんなもの、破ってやる！」といったような気持ちだと思います。"What
an ugly skin you're hiding yourself behind!" という感じだと思います。
