"Wuju" is a reference to two of the developers at Riot Games. Namely, Andy Woo and Jeff Jew.
"Wuju", or "Wuji", is the grey field a taijitu (the yin-yang symbol) is traditionally shown on, symbolizing "nothingness".
It bears similarity to "Wushu", the collective name of Chinese martial arts, mostly known as Kung-fu in western countries.
Master Yi was one of the champions chosen for the Ionian pool available during the Ionia vs. Noxus match. However, he was not one of the selected champions.
The goggles Master Yi wears (known as the Seven Lenses of Insight) seem to be an over-exaggeration of trifocal Night Vision goggles, and according to his background, provide a similar effect, allowing him to "see across a wider range of the spectrum".
His costume and the goggles bring strong resemble to Sam Fisher from Splinter Cell game franchise,
Master Yi's dance is based on Napoleon Dynamite. Notably, he shares his dance's source with Šablóna:Ci, but her dance is a different part of the same dance.
A fan joke video give birth to a popular troll build called Dunkmaster Yi, focusing on going really fast, and the catchphrase "get dunked!".
The effect that occurs when Master Yi gets a kill or assist on a champion while Šablóna:Ai is active bares a similar effect to the explosion effect from Šablóna:Cai.
This skin's lightsaber changes colors based upon Šablóna:Ai current state: blue (normal), green (passive), red (active), purple (passive and active). This is similar to the Šablóna:W games which had blue, yellow, and red lightsaber stances; each altered the speed and power of attacks.
