In Kid Icarus: Uprising, Pyrrhon speaks in binary saying "01001011010010010100110001001100", which is ASCII binary for "KILL".
In Super Smash Bros Melee, Pit's trophy has the words "Will he ever fly again?" imprinted on it, referencing his absence in the gaming market, and his eventual inclusion in Brawl.
the Komayto of Kid Icarus bares a striking resemblance to Metroids.
Komayto
Metroid
This Is seen to many as an homage to Metroid, as the original Kid Icarus ran on the Metroid engine.
This connection is pushed further in Kid Icarus: Uprising when in the chapter Chaos Vortex, Pit says they look like Metroids, but Viridi, The Goddess of Nature, says that can't be, as the universe of Kid Icarus and Metroid are different.
Also the name Komayto comes from Kometo, which in turn is short for Kometoroido, which means "Metroid Child." in Japanese.
The Idol (Basically the trophies of the Smash series) description says "While this creature resembles a certain alien-life form,The last Komaytos is not in captivity, Skyworld is not at peace..." referencing the opening of Super Metroid.
Also in Uprising, Pit references Nintendogs. While fighting the first boss, Twinbellows (A two-headed dog) He says "Old Pit's gonna teach this dog some new tricks. Were gonna rack up some serious Nintendogs trainer points together."
In Kid Icarus: Uprising it is implied that Pit rarely, if ever removes his clothes. He says that it is part of the "Angel Code of Conduct" and that his bare body would be damaged by hot springs, but it's revealed in a random conversation between him and Palutena that he's just trying to save money on laundry.
The story of Icarus (The boy who flew too close to the sun and feather and wax wings and died.) is referenced in the games. In Kid Icarus: of Myths and Monsters, Pit flies toward the sun, and his wings fall off. In Kid Icarus: Uprising, This is referenced as Palutena's power of flight only lasts five minutes before his wings burn up.
This might also explain why Pit can't fly on his own.
In Chapter 17: The Aurum Brain, it is revealed that Pit doesn't know how to read.
