Wow yeah you're the only person in the entire world who likes Articuno
It's true though for the most part. I've never met anybody else in person who considers Articuno to be their all time favorite pokemon like I do. Barely anybody online remembers much about Articuno. I look through forums all the time to see what the most popular Pokemon are, and mostly people tend to remember Articuno as one of the following:
-Irritating boss in PMD Rescue Team
-The pokemon owned by a general in Pokemon Conquest
-That bird you can skip in RBYFRLG
-A Legendary that can't do much in competitive play.
It's always a Pokemon like Mega Rayquaza, Goodra. Lucario, Charizard, etc that everyone seems to love, yet it doesn't seem anyone remembers the Kanto Bird trio as much. Besides Ho-Oh I truly believe the Legendary Birds from Kanto are the most neglected Legendary Pokemon in general at the moment. That's why I'm very disappointed to see they didn't get their chance to shine in Pokken Tournament as I think at least one of them would have been a great fighter. I may like Articuno the most but I wouldn't mind seeing Zapdos or Moltres either.
