Characters with background connections in the story typically have styles or moves in common. For example, Heihachi and Kazuya Mishima, by virtues of familial connection and studying under the same Advanced Mishima Style Fighting Karate discipline, have very similar moves and a signature "crouch dash" stance for pretty much their entire appearances in the series. Jin Kazama, when he debuted, also had the same Mishima fighting style, though he mixed this with Kazama Style Traditional Martial Arts as practiced by his mother, Jun Kazama. For storyline reasons, starting on "Tekken 4", he forwent this in favor of Traditional Karate, a completely different discipline that technically made him an entirely different character, while his old movelist was given to his demonic form, Devil Jin. Meanwhile, there are some characters who were formerly clones of each other before they diverged and gained unique moves, such as Lee Chaolan (a clone of Marshall Law), Anna Williams (a clone of her sister, Nina), and Armor King (a clone of King). Still further, there are also characters who are replacements or "successors" of older characters; this happened principally in "Tekken 3" due to the significant time skip, though some older characters later returned alongside their successors anyway. Examples include Julia Chang (replacing her adoptive mother, Michelle), Hwoarang (replacing his mentor, Baek Doo San, who later returned) and as mentioned above, Jin Kazama (replacing both of his parents, Kazuya and Jun, the former of whom later returned, while the latter was replaced by Asuka Kazama).
