Komodo Monday is an evil doppelganger version of Komodo Saturday and major antagonist from The Secret Saturdays. He is a the leader of the Monday Family. Unlike his real counterpart, Komodo Monday can speak perfect English, is really smart, and can make his body impervious to damage as opposed to making himself invisible. He also looks almost identical to Komodo Saturday except he has black spots on his back. His is one of the main antagonists from the episodes "Black Monday" and "Paris is Melting".
Unlike the rest of his family who relish in causing harm to others (especially their original counterparts), Komodo prefers to act in the shadows. He is very patient and is good at manipulating others to do what he wants. He is considered the unofficial patriarch of the Monday Family due to him ordering the rest of his family around. While he is not as cruel as Zak Monday or as aggressive as Drew Monday, he is very bossy towards the rest of his family (much to their annoyance). Though he has an unstable relationship with the rest of his family except for Zak, he knows how to force others to do his bidding.
After Zak Saturday touched the Smoke Mirror, Komodo and the rest of his family escaped the Shadow World. While the Saturday's were separated, he covered his back with bandages to hide the spots on his back. For most of the episode, he acted exactly like Komodo Saturday. When his family was exposed as imposters, he revealed his true self and the fact he can talk. Once the Saturday's were captured, the Monday's revealed to them that they would take their place in the Shadow World and they would take the Saturday's place. Once the Saturday's escaped, the two families fought. Komodo Monday bested Komodo Saturday with his durability. Once Zak Monday obtained the Smoke Mirror, he attempted tom imprison his own family, but he and the rest of the Monday's were sent back to the Shadow World. Before the episode finished, it was revealed that Zak and Komodo escaped the Mirror again. Free once again, the two set off to do whatever they want while leaving the rest of the Monday's trapped.
Paris is Melting
Komodo Monday returns in the episode "Paris is Melting" as one of the main antagonists. Using Zak Monday's fang, they manage to gain control of Fiskerton Saturday and force him to attack the homes of the Secret Scientists. Zak Saturday managed to save Fiskterton and they along with Komodo and Zon escape and go to the Louvre per Komodo Monday's request. Once they arrived, Zak Monday gained control of Zak Saturday's animal companions. Komodo Monday then revealed that the Smoke Mirror was repaired and that he wants Zak Saturday to go into the Shadow World to steal the Monday's airship. Since it runs on antimatter, reality would warp around it and the Saturday's would take the blame. The point of this is to ruin the Saturday's lives. Zak Saturday agrees to his plan to prevent Zak Monday from harming his family and he enters the Shadow World. Unbeknownst to him, Komodo Monday allows Zak to use Fiskerton, Komodo Saturday, and Zon to cause as much destruction to Paris as he wanted. Once the Monday's airship entered the real world, Zak and Komodo commandeered it to bein creating chaos. To their shock, Zak Saturday had drained the airship of its power. Zak and Komodo Monday were sent back into the Shadow World and were greeted with the rest of their family, who were very angry with them. The episode ends with Komodo trying to convince a child to help free him again, but the rest of his family pummeled him before he had the chance.
