Teisel Bonne

Teisel Bonne (ティーゼル・ボーン) is the leader of the Bonne family of air pirates, and is in charge of their battle tactics. Teisel is the oldest son of the three siblings in the family, and he cares deeply for Tron and Bon Bonne. He holds a grudge and rivalry towards Mega Man Volnutt for continuously beating him and his family.

Teisel is extreme in his emotions, either being very angry, tearing up and crying, or being extremely excited. He has a very individual laugh he often uses whenever he is excited, which is high pitched and slightly insane in nature. Despite his somewhat rough personality and tough appearance, Teisel is a intellectual person and a great strategist that takes his responsibilities seriously. He creates all sorts of detailed battle plans and schemes that aims to the family's goals while while keeping all of them out of serious danger, and is able to invade almost any island easily with their machines, specially the Gesellschaft. After a mission, he holds a review meeting to assert their strengths and weaknesses to improve, avoiding making the same mistake twice. Teisel is also a skilled pilot of combat mechas like the Gustaff, Marlwolf, and Blitzkrieg. Teisel loves reading books, and his room in the Gesellschaft is filled with them, which vary from business principles to manga. Besides books, he also likes anime and toys, and his hobbies help him cope with the sadness of his parents' death.

The Misadventures of Tron Bonne
Without telling his siblings, Teisel loaned one million Zenny from Lex Loath in Ryship Island to finance the construction of the Gesellschaft, the main transport of the Bonne family. To be able to pay his debt, Teisel went to the Nakkai Desert alongside Bon and six Servbots to search for its ruins, which is believed to have a valuable Refractor known as "Diana's Tear". They are able to find the gate of the ruins, but one of Loath's men, Glyde, attacks them with the Rafale saying that the payback time is long over, and now he must work for it. Teisel fights against Glyde, but he is defeated and captured alongside Bon. When Tron loses contact with Teisel, she gets worried and goes to his last known position, finding the Gustaff damaged and the Servbots scared and crying. The Servbots tell her what happened and they return to the Gesellschaft, were they find Teisel's receipt for the money. Tron is surprised by how much money Teisel owns, but despite the large amount, she is determined to pay his debt.

After obtaining the money needed, Tron is able to pay Teisel's debt, but Loath tricked her and captures her too, and she meets with her brothers in Loath's dungeon. Teisel laments that Tron got involved in the situation, and informs her that Loath has been shanghaiing Diggers to make them work for him to find the legendary "Sleeping Colossus", and Teisel was the one who found the Golden Refractor needed to awake it. Tron contacts the Servbots and they rescue the three siblings with the Gustaff, and Tron has the idea to take everything Loath found before they leave. They find the Colossus and Glyde appears with the Rafale to finish them, but he is defeated. Loath then activates the Colossus, and the building began collapsing, the Bonnes barely managing to escape alive. They return to the Gesellschaft and attack the Colossus, but it isn't affected by their attacks and Loath attacks them, making Teisel fall from the Gesellschaft. After the Colossus defeat, Teisel is rescued.
