Ho-Boe has gray hair with white streaks on the sides, blue eyes and has a large belly, described by Stormy as "porky". He is shorter than Musa due to old age. He wears a red suit and pants, with a purple collared shirt and tan shoes.
His hair was a darker shade of blue with lighter blue streaks on the side and is tied up with a red hair band. He wore a red collared jacket with no sleeves and wore a light green shirt underneath it. On his right arm he wore a gray wristband and on the left he wore a gray beaded bracelet, above ankle jeans and orange sandals.
He wears a red blazer, underneath it is an ivory dress shirt, and a blue bow tie.
Ho-Boe is a loving father and he was shown to be happy to see Musa, but when he learns of her concert that was being held, he angrily rejected the idea and threatened to send his daughter to another school. This was out of fear that he would lose his daughter just as he had lost his wife. Ho-Boe can be judgemental as he quickly dismissed Riven as a disrespectful and arrogant rebel but when he saw how helpful he was when Stormy attacked his daughter, he changed his mind and also allowed Musa to stay at Alfea.
He also deeply misses his wife, Matlin.
Ho-Boe first met Matlin at a concert where he spoke to her afterwards and told her he had a song he wanted her to sing. After she promised to come by the next day, he stayed up all night writing the song for her. They fell in love soon after. And soon, Musa was born. One day during a concert, Matlin fell sick. Some time later, she died. After her death, Ho-Boe went through the house destroying all instruments and songs and losing interest in music due to the trauma of Matlin dying at her musical concert.
He makes his first appearance in "The Show Must Go On!", he was invited to Red Fountain for Musa's concert which he greatly disapproved of due to his past trauma. Father-daughter were outside arguing, firstly about Riven's attitude and finally, Musa's intent on following her mother's path. Ho-Boe wants her to find another dream to follow because from his experience, music careers will not help them no matter the passion. When Musa refuses to back down, Ho-Boe angryly said that this was her first and the last concert, because he was afraid to lose his daughter as well.
Ho-Boe did still attend the concert and is brought to tears by Musa's own song, he was deeply moved and his heart began to melt. He happily claps for Musa but is then attacked by Stormy who had been hiding in the crowd, seeking out vegeance against Musa for her previous defeat. He is greatly weakened and was used a leverage by Stormy. Musa was about to deal with Stormy but when the latter warned her about her destructive musical power could hurt innocent people, she stopped. But then, Musa asks everyone to sing with her. It took Riven's encouragement to finally get the audience to sing and Stormy was defeated. Ho-Boe was then helped up to his feet by Riven, the person he had dismissed earlier, and accepted he was wrong of him. He then enjoyed the rest of the concert.
He is then seen with his daughter visit his deceased wife's grave. It appears that Ho-Boe was able to move passed the grief and trauma.
Ho-Boe's most recent appearance is in the episode "The Singing Whales". Musa contacts her father as it is the Day of the Singing Whales and asks if he is currently at the Song Wharf to which he replies yes. Musa then asks her father to show her the whales. After Tritannus takes the seal from the Pillar of Balance, causing an imbalance to the worlds, Ho-Boe witnesses the chaos that Melody is experiencing as well as the disappearance of the singing whales and thanks to the disorder his call was cut and prompted Musa to go to Melody.
He happily greets his daughter and her friends and thanks them for saving Melody. Musa then tells him that she deeply misses her mother and that she would want to use her wish to bring her back but chooses not to as it would not be correct. Ho-Boe comforts her and says that her mother would be very proud of her and that she is happy that her song lives within her.
- Issue 8: Heart of a Fairy (mentioned)
- The name Ho-Boe comes from the Oboe, a musical instrument.
- Ho-Boe could also be a pun on the word hoboe, which is a pejorative term for a migratory worker who has no money.
- In the 4Kids version, Ho-Boe was born a prince but chose to give up his title to be a musician. When Ho-Boe and Matlin fell in love, she gave up her classical training while he gave up his royal claim for each other.
- This ultimately created a plot hole within 4Kids canon in their attempt to make Musa the princess of her homeworld as once Ho-Boe renounced his royal status, his descendants would never be recognized as part of the royal family, which would mean that even if Ho-Boe had royal blood, Musa would never be recognized as the realm's princess.
