Trivia

 * He is right handed.
 * His brother, Wu, is a lefty.
 * This is ironic, due to the stigma that left-handed people are evil because the Devil is left handed and being left handed is the sign of the Devil.
 * The reason this is ironic is because of Garmadon being one of the two Lords of Darkness while his brother is know as the Good Brother in the legends.
 * What disproves this stigma even more is that the First Spinjitzu Master (who is basically Ninjago's version of God) is left-handed while the Overlord (Nate) is right -handed.
 * Oddly enough, even though both he and his wife are right handed, Lloyd turned out left handed like Wu.
 * However, this could be due to Lloyd's right hand being cut off when he was young and he never learned how to properly use his prosthetic.
 * Also, Lloyd could've inherited this trait from his grandfather.
 * He is one of the three Allies to be right handed, the other two being Misako and Dareth.
 * His middle name, Demick, is a reference to his original name in the show. Before he was Garmadon, he was Demick, but it was changed during production.
 * This reference was fully intentional.
 * He, along with Wu and Misako, nearly forgot what his actual last name was until Chyenne found it in an old document. Turns out the reason they stopped using it was because they got made fun of for it when they were young because of how stupid it sounds.
 * There's a long-standing rumor that Garmadon had been banished to the Underworld for thousands of years. This is not true, as he'd only been down there for less than a decade. If it was true, he'd have to have been born thousands of years before Ninjago existed, as well as been banished not long after. This is proven impossible by Lloyd (who wouldn't have been born if this scenario was true), and Misako and Wu (who are less than 3 years younger than Garmadon).
 * By the time the Ninja were first brought together, Garmadon was merely 1,980 years old; less than two millennia. Still many centuries old, but not as old as people think he is.
 * He's listed as "Crow" in Zane's contacts because crows are associated with darkness and typically evil fictional characters, like how Garmadon used to be evil.
 * Garmadon's eyes glow solid red in pitch black darkness, even when purified. Like his younger brother, it terrified their father into putting nightlights everywhere
