The following characters appeared in the episode "Gekko Improvises":
Gekko is climbing down one of the buildings in the town. As he lands, he introduces himself to the viewers, and starts explaining that the most awesome thing about being a hero is stopping any villains. Suddenly, as if on cue, he hears a sound coming from one of the buildings. It reveals to be Luna Girl, who is stealing presents all over the town. As Gekko looks at her, presumably thinking of how to stop the villainess, Gekko's pet Lionel then comes in from behind and squeaks to get his attention. In response, Gekko is surprised at his appearance and says that he is not supposed to be with him at night, especially during missions. As Luna Girl finishes stealing the presents and places them down on the ceiling on one of the buildings, Gekko tells Lionel to stay behind while he stops Luna Girl. With that, Gekko uses his Super Lizard Grip to scale the building that Luna Girl is on while using his Super Gekko Camouflage in order to sneak in and get the presents. However, Lionel starts to join in as well. After a few tries, he manages to climb onto the building and run towards Gekko, while he starts squeaking. This grabs Luna Girl's attention, and soon enough, she notices Gekko taking the presents away from her. She then fires her Luna Magnet towards him, and she carries him away.
Back on the ground with Lionel, Gekko explains to the viewers that his plan did not work because Lionel accidently revealed him to Luna Girl. He then explains that if an idea backfires, you can come up with something else, or improvise, and asks the viewers to watch. Going back to the rooftop, Luna Girl is deciding which present to open first. Suddenly, she hears another squeak. Thinking that Gekko is back again, she gets ready to fire her Luna Magnet at him. Instead, she finds Lionel and is confused at his appearance. Soon enough, using his Super Gekko Muscles, Gekko grabs Luna Girl's Luna Board and starts spinning her around, finally stopping as he lets go, flinging Luna Girl far out of sight.
As Gekko and Lionel high-five each other, Gekko states to the viewers that all he had to do was improvise, which was to use Lionel as a distraction for Luna Girl, and the short ends.
When an idea backfires, improvising can be the next best option.
After Gekko flung Luna Girl to the moon, it was never specified if she actually landed there or not.
