The character Tekken is a reference to the Namco fighting game series of the same name. When first introduced in Hyperdimension Neptunia Victory, she mistakenly calls herself "Harada", which is a reference to the creator of Tekken, Katsuhiro Harada.

In the English version, Neptune confuses Tekken's name for "Taken" and thinks she is "That cool actor from that movie where you throat chop everyone to rescue your daughter!" This is a reference to the film Taken starring Liam Neeson.
