Man I really, but really need someone who normally posts about ships to answer this:
Is Brambleclaw x Cloudtail a bad, good or weird ship????
It's not a ship I've thought about that much, but I think it's good! They have some obvious chemistry from both being Firestar apprentices. I could see Cloudtail being especially supportive to Bramblepaw/claw if any cats still give him shit about being Tigerstar's son, since Cloudtail would be especially aware that your parentage doesn't define the sort of warrior you are. And they're both big fluffy guys!
Cloudtail is a little bit older than Brambleclaw, which fits my general preference of older tom partners for Bramble. Cloudtail is more experienced in life and love and Brambleclaw is very eager to learn.
I don't see this happening instead of Cloudtail/Brightheart (especially because I always hc Cloudtail as trending rather straight), but I've been pretty vocal about imagining Brightheart being enthusiastically in favor of Cloudtail having a tom to fool around with. I bet Brightheart acts really motherly toward Brambleclaw in this scenario. I can see the three of them all curling up together :3
So tl;dr it's good, anon!
