Obsidian
History and Lore
For the longest time, the only two black cats known in The Bushes Subcolony would be Dusk and Band-Aid. Obsidian would ease their way into streams casually, almost not even being noticed. Band-Aid and Obsidian appear similar, but Band-Aid has an older scruffier appearance while Obsidian is more youthful with other iconic features.
As for their origin and why they would not be present on the channel for over a year before showing up is completely unknown or even acknowledged for the most part.
Personality
Obsidian originally was much more skittish in nature, but not completely shy and uncomfortable with Apo's presence. They have been more prominent and noticeable in more recent streams, including another black cat similar in appearance and showing up at the same time.
Appearance
Obsidian is an all black cat but varies wildly from Dusk and Band-Aid, the two most known black cats here, and especially Bagheera's panther like features. Obsidian has short slick fur rather than frizzier fur, with large green eyes. They seem much younger than the other cats, and their appearance has even been likened to Mooki.
Obsidian, Mooki, and the third unnamed black cat have all appeared around the same time and are similar in appearance hinting at a deeper connection between the trio.
