Another idea I have is that I've always seen Danny as a Tutelary. Specifically a Lar, even more specifically a Lar Praestite, which is a Greco-Roman ghost. There are several ways to define it, but universally, it's a protector or guardian. Some are the ghosts of dead heroes that wish to continue protecting people, while others are straight up Hero Ghosts.
Some are referred to as Household Gods, which are minor gods under the Goddess of the Home & Hearth, Vesta/Hestia. They are meant to protect places & people, sometimes within a house or family, a.k.a. Lares Familiares, others a section of a road or crossroads called Lares Viales (I HC that crossroads within the territory of a powerful enough tutelary can’t be visited by Crossroad Demons; instead the local tutelary senses the attempted breach & is urged to deal with whatever idiot thought it was a smart idea to bring such a dangerous being to a protected area in whatever way the guardian deems pertinent), or communities/neighborhoods, Lares Compitalicii. There were those who protected the military, Lares Militaris, those that protected seafarers, Lares Permarini, & those that protect the fields, Lares Rurales.
As a Lar grows stronger, their area of influence does too, sometimes expanding to cover the range of an entire city-state, which are Lares Praestites.
I imagine that those allied with a Lar have ever so slightly better luck than otherwise, that Lares have a protective aura that only affects those who call the Lar their patron & are in distress. It wraps them in this blanket of "I'm here," "I'll be right there," "I'll fix it," or "Just keep calm, stay safe, & help wherever you can." Neutrals simply don't feel the aura, while enemies of a lower power or will than the Lar feel like they're being watched & it makes them antsier than usual.
Like, I imagine Tutelaries as being one of the few types of ghosts that don't go vengeful &, for the life of them, hunters can't figure out why the heck that is. Granted, Lares & other tutelaries typically keep their territory safe in more subtle ways, but normally Lares & other tutelaries also don't have physical bodies to interact with the physical plane with because they're usually just Earthbound Spirits.
Most ghosts have to feed on human energy when outside of the Zone, Spectra doing so by feeding directly on a person's misery causing them to sink even deeper into despair, thus making her a Wraith.
I see Danny, after coming into his own, being something like her antithesis in that he feeds indirectly off of the ambient positive energy in an area. He then replaces that energy with passive positive energy which humans feel & causes their moods to elevate slightly.

In a way, the more people who believe in Danny or have faith in him as a hero, the more they trust him & feel grateful for him & his services to the community, then the stronger his desire to protect &, retroactively, he himself will become. By ‘believe in,’ I don’t mean how one would believe in a god. More so how you trust doctors to heal you, firefighters to save you from fires, & policemen to save you from criminals. This also affects his area of influence, causing his aura & protection to stretch farther along with the boundaries of his territory.
Good things (as in luck-based) will be more likely to happen within these boundaries, but it won't stop bad things from happening. It's just part of life that you have to take the good with the bad & this is no different.
Lares also have a tendency to instill and/or amplify a sense of community, synergetic cooperation, & civil duty within an area & the people living there. Of course, even though these things are more likely to happen, it means nothing if people don't choose to act on them.
Tutelaries are just... Basically all-around, good things for a town or city. What's sad is a Lar whose been utterly rejected by the people their trying to protect. Those are the weakest sorts & generally don't have long to remain on Earth before fading.
Worse is a Lar that has lost their Pillars of Inner Strength in a tragic manner. The individuals that the Lar wished to protect above all others. Without these pillars, a Lar can become a regular ghost.
However, the worst of all is when a Lar not only loses it's Pillars, but is also rejected. It's at this point that they are susceptible to corruption. Turning them into the opposite of what they were meant to be. A horrible specter, like a hybrid between a poltergeist & a wraith, hellbent on chaos & destruction. Like a rabid animal that needs to be put down. It's no less sad than ever.
Basically, how Dan came into existence. Of course, there's more to it than just that, but this is the basics. Plus, the fact that Danny is not only half-ghost, but (at least in my HC) also completely alive rather than dead, half-dead, or a member of the Undead Legion(tm) also helps keep these bad things from happening.

Another thing that helps with my theory is the fact that Lares are typically depicted as sitting upon a throne with a dog resting at their feet (dogs being associated with watchfulness), wearing a chlamys or military cloak & crown, & wielding a Greek dory (spear), a Roman pilum (javelin), or a lance.
I tend to go with King!Danny, which would give him both a throne & a crown, as well as give him his own military. Not to mention that Danny has Cujo, which could end up bonding them & giving Cujo new powers of his own.
Cujo possibly being a Cú-síth (Pronounced: coo-she). Which are part of Irish & Scottish folklore. They are described as large dog-like creatures that have shaggy, green fur & are known to be as large as a small cow. They are also known for taking dying souls to the afterlife. So, they are a type of Psychopomp themselves.
However, he does not wear a chlamys or use a lance of any kind.
