It's funny that almost ten years after its base model's initial production the Byalant custom is still considered a prototype.

Is it possible to have a "custom" prototype?! Don't you need a mass production or a base model before you're just another variant?

they may have used spare parts that were intended to replace any damaged or malfunction parts from the original, scrap it all together with a touch of modern tech and *ta-dah* a custom model

When I saw that episode, I kept wondering who the heck piloted that thing. It was kicking tons of ass.

I found the artist account on pixiv, check it here http://www.pixiv.net/member.php?id=339474&lang=en
