The Loud House + The Owl House = The Lowl House! In this, their family name will be "Lowl". No palismans drawn. Sorry.
Lori Lowl: Her tracks would be Illusions for flair, Healing for when her siblings get injured, and mixes Healing with Potions to make healing potions to aid her when she's stressed or feeling depressed. She would have a lion palisman named Helios because the lion symbolizes leadership, fitting for her bossiness.
Leni Lowl: Her track would be Illusions for fashion shows. Her palisman is Pepper the dolphin, who symbolizes joy.
Luna Lowl: Her tracks would be Bard and Illusions for the most epic rock shows! Her palisman is Saber the tiger, who symbolizes power and energy.
Luan Lowl: Her track would be Illusions as well for her performances. Her palisman is Paw the parrot, which symbolizes our ability to go about our lives with energy in a playful manner.
P.S. I thought about giving her hyena, but eventually realized that hyenas only laugh at jokes. I needed an animal that could tell jokes.
Lynn Lowl II: Her track would be Construction so she can earthbend constructs for more intense competitions. Her palisman is Juggernaut the rhino, which symbolizes steadiness ans sure-footedness, just like earthbending!
Lincoln Lowl: His tracks are Potions and Construction for his plans and schemes. His sly and scheming palisman is Fennec the fox, which symbolizes cunning.
Lucy Lowl: Her tracks are Oracle and Abominations for the horror and occult themes they bring to the table. Her palisman is Fangs the bat, which symbolizes death and rebirth. They are the guardians of the night.
Lana Lowl: Her tracks are Beast Keeping and Abominations for her love of animals and how she's not afraid to get dirty. Her palisman is Chomp the alligator, which symbolizes wisdom, primal instincts and other dynamic traits.
Lola Lowl: Her tracks are Illusions and Healing for pageants and healing or just hiding any blemishes. Her palisman is Befana the peacock, which symbolizes beauty and power.
Lisa Lowl: Her tracks are Potions and Plant for her many experiments. She also skipped grades with her intellect. Her palisman is Bea the Beaver (they all named their palismans and Lisa's not that creative), which symbolizes creation and persistance.
Lily Lowl: Her time will come. Her time will come. And waiting for her will be her palisman, Peck the woodpecker, which symbolizes resourcefulness and curiosity.
