Description
King Ivalda began as a cancerous entity within the Mecha Dimension before a mutation transformed him into a vastly powerful robotic being. This change violently expelled him into the Human World's Pacific Ocean, where he established his base, the Mecha Palace, inside an undersea volcano's caldera.

He seeks Earth's conquest and humanity's subjugation or annihilation, viewing organic life as vastly inferior to mechanical forms. While he usually delegates combat to his generals, he intervenes personally when necessary. He displays notable fondness for his pink robotic companion, a fusion of feline and bird of prey traits.

Ivalda enforces his corrupted version of Isaac Asimov's Three Laws, termed Ivalda's Three Laws, upon all robots under his command:
1. A robot must actively seek opportunities to harm human beings.
2. A robot must obey King Ivalda's commands without question.
3. A robot must prioritize self-preservation unless it conflicts with the preceding laws.
Jun and Akudos violated these laws in episodes 34 and 49 respectively.

His military hierarchy includes General Sayokka, General Uyokka, General Mannakka, and Mister Mecha X. Though a harsh ruler, he shows unexpected concern for his subordinates' well-being, refusing to deploy unwell troops and reacting fiercely to harm inflicted upon them. His forces genuinely mourned him after his demise. A significant revelation exposed that Mister Mecha X manipulated Ivalda, exploiting his belief that he aided Mecha Dimension inhabitants.

In combat, Ivalda possesses extraordinary strength, overwhelming multiple Lightans and matching Gold Lightan. His offensive arsenal includes firing destructive lasers from his fingertips, electrocuting foes on contact, projecting combustion-inducing dark energy blasts from his mouth, and inflicting psychological torment via mental invasions flooding victims with visions of war and devastation. His endurance is formidable, surviving prolonged submersion in boiling lava unscathed and withstanding Gold Lightan's Gold Crash attack, though significantly weakened by it.

Tactically, he frequently deploys colossal robotic beasts, initially favoring animal-themed designs like turtles and dragons before shifting to more conventional humanoid mecha that often dwarf Gold Lightan. His final battle saw him attempt to replicate Gold Lightan's Gold Crash technique, targeting a pre-existing wound inflicted by Akudos, though this effort failed to eliminate his adversary.
