Universe H (Jenny Everywhere and the Lord of Hell)
From Jenny Everywhere Wiki
In one universe, Jenny Everywhere was the sheriff of a Wild West-type town. 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. With Jenny merging with her local counterpart, the two ended up on the cusp of a duel before Jenny shifted them out again. (PROSE: Jenny Everywhere and the Lord of Hell)
