Biography
She rarely appears on Earth save when she falls in love with Kyousuke Jinnai and causes a series of bizarre events that end with her love redirected to Action Commander Jealousto until his defeat by Shinken GokaiOh and asked for him to be jettisoned.

When the Gokaigers and Hurricanegers joined forces, Insarn fought against Nanami Nono (HurricaneBlue) with Luka Millfy (Gokai Yellow) and Ahim de Famille (Gokai Pink), who defeated her.

Insarn was rivaled by another highly skilled Zangyack scientist, Zaien, the one that turned Sid Bamick into Barizorg. When he arrived on the Gigant Horse in Earth's orbit, Insarn suspected that he was after her position, though he assured her he wasn't. She seemed happy to enlarge him, likely taking satisfaction in his first destruction.

Insarn, along with Barizorg, accompanied Warz Gill and an army of Gormin when he confronted Pollution President Babatcheed leading the Gaiark remnant in a rival invasion of Earth. The Zangyack and the Gaiark fought each other until the Gokaigers arrived and attacked Gaiark. Warz decided that it was best to leave so both sides would be weakened.

Later, after finding that she has no place in the Zangyack, Insarn decides to go after the Gokaigers in the Great Insarn to prove her worth to Ackdos. Four Sugormin took on GoZyuJin while her robo took on GokaiOh. It was literally disarmed by Gokaioh using the Greater Powers of the Changemen and the Maskmen before being destroyed by Shinken GokaiOh's Gokai Samurai Slash. Forced to eject when her robot is destroyed, Dyrandoh sends four Dogormin to back her up. The Gokaigers changed into representatives of the five last teams whose Greater Powers they collected. Captain Marvelous as VulEagle took on Insarn while the other four fought a Dogormin each. After the Dogormin were destroyed, Insarn was finished off by the Gokai Galleon Buster's Rising Strike. Insarn was livid of her fate before she exploded.
