>>5540653It's my take on some concepts that didn't really get fleshed out from their source material (Churai from DBO) or didn't leave the cutting room floor as it got revamped from scratch (Beerus's original role in BoG before Toriyama took over).
To summarize, Kurai is the sentient heart and soul of Darkness, comprised entirely of dark energy. A unique energy source that originates from the Demon Realm. Like the components she or it is comprised of, it embodies the malevolent and negative forces of the cosmos. Thus, Kurai is capable of corrupting and converting people into members of the Demon Clan, similar to how Babadi makes someone into a Majin Warrior. Though her method acts more like Cumber's Evil Aura since it's the same kind of virus-like invasion/possession.
Like her energy source, she can utilize negative energy and manifest shadow dragons by infecting dragon balls. In many ways, she has a kinship with the Ancient Evil Saiyans and demonic entities like the Makyans as well as the Demon Clan Namekians. I guess you could also say the same with Janemba and Majin Buu since it's the same vibe.
Most importantly, she's the stand-in for
>>5537729 since like I mentioned before, I'm not using the Super storyline where Beerus is the one who seeled Elder Kai for this universe (Universe 0/13). Thus, I thought it fitting to make her carry the original role of Beerus. Essentially, a villain who was said to have infected the saiyans with their evil like a virus and gave them their ruthlessness (Note: I'm not going to use this as a scapegoat for the saiyans since even without it they're not good people. Most of them anyway. Only enhance/amplify their downward spiral.)
