"I may not always understand you, but I still love you". *Grigon would first be seen ordering the Communiverse to allow him membership, threatening to kill them if they did not comply. Elio traveled to Grigon's ship to negotiate with Grigon, but he was imprisoned after insulting Grigon's parenting skills. Grigon prepared to destroy the Communiverse, but he was forced to surrender after discovering Elio had kidnapped his son.

As a demonstration of the Hylurgian Empire's might, Grigon wanted Glordon to don his carapace in front of the Communiverse. However, upon realizing that Glordon was replaced by a clone, he broke off his deal to surrender. After failing to find Glordon, as he had accidentally sent himself to Earth, Grigon ordered his army to execute everyone in the Communiverse.

Within hours, Grigon's forces captured everyone in the Communiverse. Fortunately for everyone involved, Elio returned with Glordon, though he was on the brink of death due to the colder environment. Grigon ripped himself out of his carapace to swaddle Glordon with his silk. After seeing how Elio saved his son, Grigon left the Communiverse alone, and it's implied he gave up his conquering ways.*
