"The Destruction of Johnny X"
"Johnny vs. The Mummy"
IJohnny is the first part of the 52nd episode and the 103rd episode overall.
Johnny asks Hugh if he can have a cell phone, which Hugh denies as Johnny would then lose it. Dukey urges Johnny to go on, complaining about how his sisters have them and he doesn't, and then explains various reasons what could happen if he didn't have a phone. Hugh takes him to the phone store, where Johnny wants an xPhone but instead gets the Blah Phone. The Blah Phone has nothing cool, but it's cheap so Hugh buys it. Later, Hugh wants Johnny to show Lila at dinner time the phone. After that, the sisters upgrade Johnny's Phone so it could do various things. After having fun with the phone, the phone goes mad and robs the bank, then goes even madder and adds a laser mode, so it can destroy the world. Meanwhile, at the Military Base, the headmaster realizes the laser targets the xPhone is using are gas stations, power plants, the nuclear plants, Porkbelly's Explosives, Johnny Test's house and the base itself. Realizing there's no situation to stop the lasers from firing, they run for their lives. Johnny realizes that the phone relocated the space lasers from the Test's lab. Then The Test sisters and Johnny went to look for the phone but they managed to find it but it was too far away so then Johnny repositions them so it can attack the phone so the world doesn't explode. Then, at dinner, Lila wants to see the phone and finds out that it was broken then Hugh yells "JOHNNY!!!", but Johnny doesn't care.
- iJohnny is a reference to the iPhone, iPod, iPad, and other Apple devices that have a small "i" in front of their name.
- The phone acts like H.A.L. 9000 from 2001: A Space Odyssey, right down to the voice, and a single red eye.
- This is one of the few episodes where Sissy's crush on Johnny was more obvious.
- The xPhone a reference to the iPhone
The xPhone should not hack into the military base, because phones cannot hack into any base at all.
