Who is Heihachi Mishima’s illegitimate son introduced in Tekken 6? Lars Alexandersson.

Lars is introduced as a leader within the Mishima Zaibatsu’s Tekken Force, but he rebels after Jin Kazama uses the organization to wage global war. During the Tekken 6 story, Lars loses his memory and travels with Alisa Bosconovitch while trying to uncover his identity and stop Jin’s plans.

His family connection is revealed when he encounters Heihachi. Lars is Heihachi’s illegitimate son, making him Kazuya’s half-brother and Jin’s uncle. The revelation also explains why Lars has a place in the Mishima family conflict despite not appearing in the earliest games.

Lars is not merely a family-tree addition: he is the central protagonist of Tekken 6’s console Scenario Campaign. He leads the rebel group Yggdrasil and opposes both Heihachi and Kazuya, choosing to prevent the Mishima Zaibatsu from becoming the instrument of another family member’s ambition.
