Perhaps the only evidence to the Great Hero's existence was the Bracelet, but inside the relic lurks an unknown entity manifested from all the magic. Taking on the form Iron Tail is most comfortable with, she is simply named 'Bracelet' by the young Hero - though that in itself speaks volumes of what she might be capable of. Only Iron Tail can see and speak with her though but her existence has been proven from all the magic granted to the boy. She seems to share Iron's personality and appearance to an extent (proven that she adopts these depending on her owner), but her true alignment is debatable. If there's one thing that's certain though: if it wasn't for her magic, Iron Tail wouldn't be the Hero he is now!
Here's one character I was first unsure of but learned to like, but mostly because of both her potential as Iron Tail's biggest support, and Iron Tail's biggest threat. Why is she a threat? Because she's not exactly a 'Hero'. She only follows/adopts Iron Tail's personality, but if I have to describe her, she's more close to an animal: she doesn't have much moral judgement but is instead guided mostly by instincts. A possibility is that Bracelet could easily take over Iron Tail's body (refer to the previous 'Overtaken' picture) but it's either she doesn't want to, or she just doesn't know she could. The Overtaken form is most definitely Iron Tail's strongest form (despite the fact his mind is taken over by Bracelet), but even Ashes warns Iron Tail not to use it too much because she secretly fears Bracelet will one day take over him completely. She's possibly one of the strongest characters in the story due to the fact that she is the Bracelet itself.
In her revamped version, she can appear outside of the Bracelet, but Iron Tail is still the only one who can see and talk to her (via his mind), and she can only go as far as three feet away from him. You can either sympathize with her or be afraid of her, but she's definitely the one that makes Iron Tail the hero he is now.
