Universe J (Jenny Everywhere and the Lord of Hell)
From Jenny Everywhere Wiki
In one universe, Jenny Everywhere was a ‘Knight of the Realm’. Another Jenny briefly shifted into this universe while trying to defeat Lord Grallyx, taking him along with her so as to retcon him into the fabric of that universe. He ended up as a Dragon that the Knight Jenny was riding out against. (PROSE: Jenny Everywhere and the Lord of Hell)
