Divine Wolves

These are the wolves born from Fenrir's intermingling with other divine beings like the moon and sun goddesses or the nature deities. Fenrir is quite the womanizer being the son of Loki with a tiny bit of Asgarian blood which gives him his own devilish charms. Divine wolves are more powerful than the rest and they can only be killed by celestial or chaos weapons.

Example: Skoll and Hrod (chases the moon and sun to keep them on time)

Wolgriff

The winged wolves that are created when Fenrir mated with a griffin. They are excellent at aviation and experts at stealth. They are used primarily as aerial scouts but they are not as strong and as durable as the other wolves.

Example: Lyubim (serves as Ruby's courier for her messages to Martis)

Centaur wolves

Centaurial Hybrids are one of the most unique species of wolves that have interbreed with other Centaurial kinds to propagate. They are very powerful and skilled in warfare. They can be very violent and ferocious but their loyalties are unparalleled.

Example: Fragarax (The first Centaurial wolf to acquire a name given by Ruby) 

Arctic Fleet Wolves

Arctic wolves are Fenrir's children with other Frost giantesses. They are born and raised in Jötunheim so they are fit to survive in harsh and desolate frozen environments. They cannot handle the heat of the Abyss so Ruby had to create a spell with the help of the Druids to create a rune that would give them eternal frost to comabat the heat.

Example: Alaska and Runa (She-wolves that serves as Ruby's caretakers)

Direwolves

They are mostly descendants of Fenrir's descendants so they are more like regular wolves except bigger and more intelligent. They can understand the human tongue as well as the language of the forest.

Hellfangs

Hounds that are made of fire and stone. They are partially Muspel, meaning that they have fire giant blood in them.

Warewolves/Wolfmen:

Wolves that can transform into humanoid form. They are not typically Fenrir's children but they are born when female humans bred with divine wolves and other wolf spirits.

Druid Wolves

Warewolves that can perform magic, mostly runic.

Hopes that this helps you to imagine Ruby's Wolf Babies!
