Joshua

Joshua is a dog who is the father of brothers Jake, Finn, and Jermaine. He and his wife Margaret adopted Finn as a baby.

History
Joshua first appeared with his wife in one of Finn's flashbacks in the episode "Memories of Boom Boom Mountain." They find Finn after he has soiled himself causing him to be stuck to a leaf and cried for a whole day with no one helping him. They are the first and only people to stop and help the seemingly abandoned baby Finn while everyone else just walked past him. Joshua seems to be disrespectful and aloof. He speaks in a 1940s Mid-Atlantic accent.

Joshua returns in "Crystals Have Power" where his ghost appears from beyond the grave encouraging Jake to fight back against the Crystal Guardians of the Crystal Dimension after Jake takes a vow of non-violence. Jake became upset when he remembered Joshua telling him that "Jake would hurt everyone". Jake also sees his brother Jermaine in his flashback. To be noted, Joshua was trying to tell Jake that "Jake would hurt everyone... who is evil." Joshua's personality is demonstrated as a very old-fashioned manly male who is willing to push his sons to fight, particularly when they need to.

During "Crystals Have Power," Jake says "stupid ghost dad" when talking to himself out of frustration after Joshua says "Come on, punch them Jake. Punch everybody. Why not? Come on, why not!" Also, when Joshua brings Jermaine to see Jake, Jake asks him if he is dead, implying that Joshua is already dead (Jermaine was not dead, he was just sleeping at the same time).

In "Dad's Dungeon" Joshua makes Finn and Jake (through an old holographic video) explore a dungeon to obtain Jake's Family Sword at the end of it. He actually did this for Finn since he knew he wouldn't be around at the time, and wanted to toughen up Finn.

Death
Joshua is confirmed to be deceased. He, as well as his wife Margaret had passed away prior to the events of Adventure Time. The cause of death is unknown. In "Dad's Dungeon", the hologram video shows Joshua being attacked by a Giant Monster, but this was apparently not the cause of his demise, because that video was recorded when Jake was a baby, while the flashback in "Crystals Have Power" showed Joshua was alive when Jake was older.

Abilities
Although Joshua does not possess magical abilities like his son Jake, he is still a really tough, skilled dog who had created a reputation for himself in Ooo prior to his death. He prides his physical toughness and the ability to fight and stand up to any evil that gets in his way. Joshua also has some skills in magic, knowing spells such as the one to unsummon a Demon that he used to make his sword out of it's blood. He may have some swordsmanship abilities, but they have not been demonstrated as of this time. After his death, he still possesses some abilities, such as the ability to talk to Jake in his dreams if needed.
