I was going to give her a giant robot as external skeleton. But that's just cliché. If I'm really going to develop this character into a comic series, I would make her fight ridiculous giant robots instead, as her real size!
...somehow the big drill reminds me of gurren laggan... but I love this one!! after looking at her color code I think this one will become a very great character... and since she's a princess...may be a royal dress will become a great additional to her design
