History

Lecuum came from a world where his people relied on the power of imagination, and have extinguished their supply. Lecuum manipulated a cartoonist named Sasayama into adding a strange new radio wave to the Tokyo Tower II and started broadcasting, sapping up the imaginative qualities of the humans. After the humans began their retaliation, Lecuum transformed into a giant form to try and fight back, but a carefully aimed high-frequency radio-wave destroys him, ending the threat.

Ultraman Taiga
12 years ago, a Lecuum took Hiroyuki Kudo's infant pet Guesra, Chibisuke. Hiroyuki tried to stop him but was easily shrugged off, but he went so far as to hold onto the alien as it was getting beamed up to his spaceship. The Lecuum then pushed Hiroyuki off and let him fall to his death, but he was saved by the light of Ultraman Taiga, who saw his bravery and decided to bond with him. The Rekyum then implanted a control chip into Chibisuke and turned it into a monster weapon.
In the present, a Lecuum and his subordinates disguised as humans unleash a King Guesra on Earth as part of a monster auction. EGIS members Hiroyuki and Homare were dispatched to deal with it, but were unable to keep up with the three disguised aliens, and they disappeared.
EGIS managed to track them down again and take them by surprise near a chocolate storage facility. While Homare attacked the other two henchmen, Hiroyuki chased down the one with the control device. It revealed its true form, causing Hiroyuki to suspect that the King Guesra is his old pet Chibisuke. Hiroyuki then manages to calm down Chibisuke, causing the mind control device to stop working. What happens to the Rekyum after that is unknown. Tregear
