Señor 105

Señor 105 was a famous Mexican luchador with the "finest physique [and] the finest mind the world [had] to offer". He had one mask for every element in the periodic table and he named himself after the number of elements in the periodic table, meaning that with each new element discovered he made a new mask and added another number to his name.

While he often left Mexico to have adventures across the globe (sometimes even traversing the Very Fabric of Time and Space using his home-made Zodiac Machine), Señor 105 always returned to his house in mid-20th century Mexico City.

One of Señor 105's closest companions was Sheila, a French Sentient that lived in a balloon. (PROSE: Elementary, My Dear Sheila)

Señor 105 was a friend of Iris Wildthyme (PROSE: Iris Wildthyme y Señor Cientocinco contra Los Monstruos del Fiesta et al) and a fan of Brenda Soobie - he was unaware they were the same person. (PROSE: The Shape of Things)

History

In 1963, 105 saw Brenda Soobie live in Las Vegas. (PROSE: The Shape of Things)

In the summer of 1967, Señor 105 attended a party Brenda Soobie held in Las Vegas. While walking through the celebrations, Brenda saw 105 by the pool, teaching Lawrence Burton and Jay Eales how to make paper aeroplanes. (PROSE: Party Fears Two)

By summer 1968, Señor 105 had met several Mexican presidents, visited the Eiffel Tower, went on a boat ride with Albert Einstein, and encountered UFOs, witches, werewolves, purple midgets, and "El Hombre Invisible".

On the day of the opening ceremony of the 1968 Olympics in Mexico City, Señor 105 met Iris Wildthyme and Panda while trying to stop an army of spirits possessing piñatas from disrupting the Olympics. While 105 wrestled Axixmiqui, the leader of the spirits, Iris manipulated the mathematical ratios involved in the dimensional doorway the spirits were creating. When the doorway was activated, the spirits were all sucked up into a mini-singularity. Afterwards, Señor 105 helped Iris repair her Celestial Omnibus and gave her a 1968 Olympics bracelet and the mask he made for titanium as parting gifts; using knowledge gaining from observing the workings of the omnibus, 105 was able to complete the Zodiac Machine.

Señor 105 once visited Tlalocan with a small boy in striped pyjamas who had a tray of chicles. Primo de la Vega saw 105 and the boy while dreaming. (PROSE: Against Nature)

While travelling with Iris Wildthyme and Panda, Señor 105 aided them in obtaining the third slice of the Celestial Gateau from vampiric versions of Mick Jagger and Keith Richards.
