King Thrash is a senile old man. He might be absent-minded, but he dotes his daughter a lot.
Despite his apparent senility, after the Strings were destroyed by Queen Poppy, when Queen Essence and King Quincy shared their realization to all Trolls that music really comes from themselves, Thrash encouraged his daughter to let everyone be what they want to be including her, showing that he truly accepts the other Tribes' music and wishes for her to do the same.

=== Friends ===
==== King Peppy ====
In the ending credits of Trolls World Tour, he's seen with King Peppy in the party doing donuts. They seem to get along with each other quite well.
=== Family ===
==== Queen Barb ====
He was fully supportive of his daughter's conquest of the Strings. However, he is usually terrified of her outbursts. According to Barb, Thrash is the one who gave her the idea of uniting the Tribes under Rock music, although the context of this is unknown. The two have a good relationship and Barb cares about her senile father's welfare.

He has most normal Troll abilities, as well as the abilities of his Tribe.
=== Leadership ===
Almost nothing is currently known on Thrash as a ruler. The only thing in relation to this is from Trolls World Tour: The Junior Novelization, where it was mentioned that Barb was expected to live up to expectations of her father. It was also noted that Barb had a lot of pressure on her to be a good Queen. Adding to this is a note from his official Trolls World Tour bio that indicates Thrash had only just retired after a long reign due to his degrading physical and mental condition, making him unfit as a King. Thrash therefore was at least beloved as a King prior to Barb taking over, and had managed to meet all expectations of his station, ruling for a long time.
=== Music ===
When he was the King of the Rock Trolls, it would have been his sworn duty to protect his music, including the red string of Rock.
He also displays some skill in playing an electric keyboard.

Due to his aging body, he has physical restrictions. He goes around in a motorized wheelchair, which limits his movement. He also has trouble doing the "horns" hand gesture; when Riff aids him in doing the gesture, he struggled with it and cracking noises were heard, indicating that he has a form of arthritis.
=== Mental Issues ===
Thrash has issues with memory and struggles with interacting with the real world, this is also suggested related to his age.

*Being voiced by Ozzy Osbourne is no coincidence; Ozzy earned the nickname "the Prince of Darkness". He's generally also considered the Godfather of Heavy Metal due to his long successful career, being highly influential on the genre of Rock music itself.
**In Trolls World Tour, Queen Barb performs a cover of Ozzy Osbourne's song Crazy Train.
**In the Trolls World Tour extras video "Tourist Map", Cloud Guy also calls Barb "the Queen of Darkness" in a nod to Ozzy.
*His name is a reference to Thrash Metal.
*Originally in Trolls, King Peppy was to have the senile disposition that Thrash has, which was the reason for Poppy's ascension to the throne. The story was re-written to have Peppy instead as a teacher and adviser with Poppy, instead becoming Queen after earning it.
*He and Peppy are the only elderly Trolls seen alive in the movies.
*As well as arthritis, Thrash shows a decent amount of hints to Alzheimer's disease, another disease that's often associated with old age. During Trolls World Tour, he had displayed a forgetfulness of the plan to steal the Strings (despite being the one to come up with the idea), gets into a state of confusion, and is unaware of what's going on around him, added with a limited emotional display. He also has fixation on a handful of things, such as repeating the lyrics of Trolls Wanna Have Good Times or his shouting of "Rock and Roll".
*During Just Sing, King Thrash was the 3rd Troll to re-color after Poppy and Branch.
*King Thrash is the first characters in the franchise to show an obscene gesture, as seen in Trolls: Holiday in Harmony.
