Following up on my last post, it turns out that Poor Yorick did design a cutie mark for Blueball Blitz, so that is the one I will be using in the future, if I need to show her mark.

The Shadowbolts in my tumblr are pretty much PoorYorick’s versions, give or take a few creative liberties. I am not sure what he had planned for their cutie marks, and truth be told I have not designed my own marks for all of them yet, although I have designed Blueball Blitz’s. It’s a robin egg being cracked by a bolt of lightning, which I think suits her personality and backstory well (see attached image). Nightshade will probably have an actual nightshade blossom as her cutie mark, though I am toying with the idea of putting either a black heart or a broken heart behind it. The rest I still need to brew some ideas for.
