Buguese

Buguese, a pale skinned Invectid, is the leader of the Big Four and second only to Mantid himself. He is one of the Spider Rider's most frequently encountered enemies, and they share mutual hate of each other. Personally, he hates Hunter Steele for the many defeats at his hands. Buguese has remained a loyal and faithful servant of Mantid, but over time, he lost faith and did not trust Mantid anymore. He plans to destroy the Spider Riders and take control over the Invectid Nation from Mantid. Lord Mantid gave him a machine called Dark Opal and told him to destroy the Spider Riders with it. However while battling them it absorbed the power from Hunter's Oracle keys, keeping Buguese from betraying Lord Mantid. He removes Aqune's mask, which was endowed with some of the Oracle's power by Lord Mantid and commented that over the years she had become someone precious to him. He is nearly killed by Mantid when one of his attacks nearly sends him off a cliff. He was saved by Beerain and Stags.

Buguese's Relationships:

Hunter- Buguese completely despises him for most of the series. He hates Spider Riders in general, but Hunter in particular bothered him for defeating him several times, and for completely seeing him as evil despite not knowing all the details. He also doesn't like the idea of Aqune and Hunter being close. Eventually, they come to somewhat of an understanding, and Buguese gives Hunter the last two Oracle Keys, trusting him to save the Inner World.

Corona- He probably dislikes her due to her being a Rider. He uses her as a hostage in order to get Aqune and the Oracle Keys back from the Spider Riders. It's somewhat ironic that he and Corona are in a similar situation at that point, because Hunter and Aqune being together is the main source of both their problems.

Aqune- He's extremely protective of her, especially in the dub. He controls her, though reluctantly. Her pacifism and dislike of fighting bothers him. He's very forgiving to her, and admitted to himself that she was precious to him.

Igneous- They don't interact much, but Buguese probably dislikes him.

Magma- He seems to dislike him a little more than most of the Riders, due to his special interest in retrieving Aqune and Portia.

Sparkle- They don't interact, though he probably dislikes her.

Lumen- They don't interact much, but he probably dislikes him.

Quake- He's annoyed by him right away, and concerned when he learns of his true identity.

Grasshop- Buguese hates him and treats him rather cruelly. He's the one who personally demotes Grasshop from the Big Four. He does save him from Mantid eventually, but only in order to face Mantid himself.

Stags- He respects him a lot more than he wants to admit, and considers him even stronger than himself. He forcibly takes over for him in Nuuma, and later leaves him there for dead, but regrets this a lot. He's surprised when Stags takes care of him after he's injured by Mantid.

Beerain- He seems to know about her feelings for him, but spends most of the series ignoring her. He does show aome concern for her, but takes advantage of her devotion to him to keep her loyal. He also leaves her in Nuuma, and then later treats her terribly when she tries to convince him that Mantid is a threat, and regrets this deeply.

Mantid- Buguese is incredibly devoted to him throughout most of the series, even though he has his doubts about Mantid's intentions, and plans to eventually overthrow him and rule himself. After Mantid gains the Oracle's power and tries to keep it for himself, and then uses Aqune against him, he becomes furious and tries to fight Mantid several times, losing and becoming badly injured.

Portia- He controls her, but eventually frees her along with Aqune.
