Senex is a necromancer and the cause of the Zombie Apocalypse that has afflicted the Hoenn Region in the time of Pokémon Snakewood. A silhouette of Senex is used on the hack's title screen.

Plot Synopsis

Senex is first encountered when the player reaches the roof of the Lilycove Department Store. When the player approaches Senex, he finishes off his current battle with the Deadly Seven's leader, Asimov, by causing him to vanish into thin air, which Senex describes as "unmaking" him. After the player defeats Senex, he flees to his base of operations in Necropolis.

When the player invades Necropolis with Steven Stone, Meteor and Sage Izumii, Senex is waiting at the top of the base, already having encased the player's companions in carbonite, ready to eliminate the player once more. After the player defeats Senex a second time, Asimov, surprisingly still alive, arrives to knock Gleis and Temulence off the top of the mountain base. Before he is able to finish off Senex, however, the necromancer recites an incantation to destroy all of Hoenn, leaving only himself, Asimov, and the player left alive in a plane of nothingness. The player then defeats Senex with the most powerful references they can think of. After Senex is defeated, Hoenn is restored to its state immediately before its destruction. Senex is defeated, but any zombies still remain scattered across the land.

After the player arrives at Gym Island and defeats the gyms there, they are allowed to enter the building labelled "Asimov's Gym." Upon entering, the building is found to be a "mess of glitchy reality", with Senex waiting inside. Senex, who has revealed that the venue they are in is called Black Rock (though admittedly not understanding the reason for the name), challenges the player in his "true form", as a level 90 Fighting/Dark type legendary Pokémon. After he is defeated for the final time, the player comments how they've been solving the mysteries surrounding their amnesia fairly fast, stating that the entire events of the game thus far, from the point of starting at Oldale Town, have happened in less than 24 hours.
