Hofucno has the highest base Special Defense stat of all non-legendary Flying-type Pokémon.
HOENN CONFIRMED (Motherfuck of water) - Lore time! Around the same time Motherfuck were created, Hoenn was confirmed. The neo-Nazis of Outcast Island couldn't control the Motherfuck that they created, so they created another hybrid by combining parts of Tentacool, Horsea and Wingull with trumpets. The Hofucno were just as difficult to control as the Motherfuck. Then one day, an incompetent security guard left a cage door unlocked, resulting in the freedom of every creation out of the neo-Nazis' lab. The Hofucno first terrorized Inavia, until some Motherfuck flew into the region and had one big orgy. Feeling satisfied, the Hofucno infested the sea and would rest until the next time they feel like terrorizing the region.
Hofucno is a Hoenn-based counterpart of the other Clovermon, Motherfuck. It is a combination of the real Pokémon Wingull, Horsea and Tentacool, as well as a trumpet. It was designed when Hoenn was confirmed for a remake.
Its design including a trumpet may be a reference to the Hoenn game's soundtrack, which heavily uses trumpets.
