The emotes contain several inaccuracies. Imps appeared as miniature lesser demons in 2001, the King Black Dragon had only 1 head in 2002, and the dwarf multicannon had 8 barrels in 2003. Even dismissing RuneScape Classic models as a possibility, giant rats and the King Black Dragon did not use their current model when RuneScape 2 was released, and the Kalphite Queen had a different model in 2004. The 2005 emote contains the most recent Ice Barrage animation rather than the original, and also uses the RSHD model for abyssal demons.
King Arthur appears in the 2003 emote, but is only referenced in that year during Murder Mystery and Underground Pass, and doesn't actually make appearances in them. He was added to RuneScape the year before, on 27 February 2002. He also did not use the model he uses in the emote until 2006.
The fancy boots, which were released on 4 June 2006 and the dragon platelegs, released on 17 January 2005, incorrectly appear in the 2004 emote. Jagex has acknowledged the mistake.
 The Ahrim's set in the 2005 emote has a different shade for the sleeves and hood than the original. This was changed on 14 March 2016.
The 2006 emote features an Ivandis flail instead of a Rod of Ivandis, only the latter of which was released in 2006. The flail was released on 22 April 2008.
Durial321 wore a green partyhat during the Falador Massacre, rather than a red one as shown in the 2006 emote. This was changed on 14 March 2016.
The 2012 emote uses the modern appearance of Tetsu equipment, which did not debut until January 2013. The original outfit could not have been obtained at the time, though, due to the time barrier in the minigame.
