Jake Harley

Jade Harley's late grandfather. He is considered a badass by both Jade and Dave Strider. However, Jade finds confrontations her and her grandfather are very intense; Jade's unusual abilities seem to allow her to communicate with her grandpa's spirit and, according to her, he is strict, intense, and charismatic. He's prone to giving stern lectures to Jade whenever they meet and insists Jade carry a hunting rifle when she leaves the house, or else "there would be hell to pay." According to Jade, he was much easier to deal with when he was alive.

Grandpa Harley also appears to be rather caring for his granddaughter, even in the after life. At one point, the pair have a conversation with each other through Jade's Gnostic Abilities. In this, we can only see Jade's half of the conversation, but it is implied that Grandpa Harley is suggesting that she take a bigger and more effective gun before she goes outside to defend herself from whatever it is that is outside. This implies that there are dangerous things outside his house that he has dealt with before. Potentially, these beasts are the same that decorate his house.

He decorated his house in multiple motifs, including suits of armor (including some more modern armors such as the Iron Man armor and the Judge armor), decrepit mummies, big game trophies, sunbleached photos of women (his 'beauties'), and globes. Though Jade doesn't mind the suits of armor, she hates the mummies and hunting trophies.

While at first it seemed that Grandpa was Jade's guardian, he, like many things associated with Jade, is a bit of a pattern breaker and it has been suggested that he is in fact not Jade's guardian. It is unknown if he ever had a wife, though he seems to have been 'buried' alone. Unlike other guardians, he isn't missing any facial features. While the other guardians have personal 'vices,' such as smoking, drinking, and puppet pornography, Grandpa doesn't seem to have one, other then his strict lectures, his interest in firearms and hunting, and his obsessive 'pack rat' hoarding.

Some of the big game trophies in Grandpa's tower appear to be chimeras; combinations of different animals. Whether these are genetic experiments, mythical creatures, or terrible abuses of taxidermy is unknown. Interestingly, one of his trophies is the mounted head of a Crude Ogre. This suggests he may already be involved with the Weird plot shit still unfolding.

According to Jade, Grandpa is an extreme polymath; he's a world-renown explorer, naturalist, treasure hunter, archeologist, scientist, adventurer, big game hunter, and billionaire. This would explain the close proximity of ancient ruins to his house and having a laboratory.

Jade mentions that he is in fact dead when she said "He was so much easier to deal with when he was alive"
