He was known as one of the key members of the International Justice League of Super Acquaintances, an alliance founded by Captain Magma. Illusionio and his alliance were responsible for multiple blindsides throughout the game.
Illusionio voted for Rylan with the rest of his alliance in She's One Tough Bitch, unable to successfully send him home. After recruiting Jason and Sophie in ANYONE WANT TO BE MY TEMPORARY KITTY?, however, IJLSA has the numbers to send Buckley home.
In If He Thinks He's Getting My Vote To Save Him, Haha, He's Wrong!, Illusionio shows authority for Captain Magma, calling him "my captain" and following orders to vote out Cierra. Illusionio frequently used the term "birth mother," which could possibly have been referring to Cierra.
Illusionio is Rewarded in The Person With The Advantage Made It To The End!? Shocker, when Will is Rewarded with Reward Pass by London. However, Illusionio only recieves a Dud Reward. In a confessional, Illusionio confesses his love for his close friend Will, and later attempts to make a love potion. He confesses his love for Will, putting his friend in an uncomfortable position. When Captain Magma shows to be nervous about the vote at the elimination, Illusionio reassures him by telling him that all is well. Indeed, with the help of Cara DeGrossi's vote, IJLSA is able to send Carmonte home.
In HEROES DO NOT DRINK THE BLOOD OF OTHER HEROES!, Illusionio explains to Cara that Jason is afraid of her. Later, when Jason wins immunity, Illusionio and the other IJLSA members pressure Jason into Rewarding them. Jason ultimately chooses Captain Magma, most likely because he is the leader. After the challenge, Illusionio calls London a bitch. Illusionio shockingly recieves two votes at the elimination held in the hut due to Cara's injury. However, he is not sent home, recieving one less vote than London.
When Captain Magma is eliminated at the double elimination in Knowing Things Is Mainstream, I Like Surprises, Illusionio assures him that he will take over as the leader of the now crumbling IJLSA. Captain Magma harshly objects, however, and points to Will as the new leader. Illusionio accepts this, saying Will is far more rational than he is.
According to an enraged Cara, Illusionio told her he was the one who voted out Rylan in the previous episode. Cara seeks vengence on Illusionio in TIME TO BURN BURN BITCHES, and sends him home with the help of Lindsey and Jason, (who was a former IJLSA member).
At the Finale, Illusionio tells the producers his jury vote is for whoever Captain Magma voted for. In effect, he votes for Cara to win.
