Electric Fakemon based off of tool-using in Primates. First stage is inspired by the story of the spear fishing Orangutan and other cases of primates fishing, but in this case the Pokemon has taken an old broken umbrella and "fishes" for lightning.
The form it evolves into depends on which stat is higher, Attack or Sp. Atk. It's considered the same Pokemon but they have different movesets (like Meowstic) and the stats for Attack and Sp. Atk would be swapped. The hammer is reference to Thor and the key a reference to Benjamin Franklin.
