Cassie Cage's History
Some time after the Netherrealm War, Johnny Cage and Sonya Blade got married and had a daughter, Cassie. However, Sonya's perceived prioritization of work over her own family led them to divorce, much to Cassie's sadness. Being the daughter of a high-earning Hollywood actor, Cassie was somewhat spoiled, although her attitude changed after she was kidnapped by the Black Dragon. This experience convinced her to join the Special Forces, where she would be trained by both of her parents in combat.
Inheriting the charisma and cocky wit of her father and the stern, tough as nails attitude of her mother, Cassie quickly rose through the ranks to become team leader and, eventually, sergeant. She managed to defeat the fallen Elder God Shinnok single-handedly, even in his full demonic form, and eventually attained the rank of commander.
Initially, Cassie harbored deep insecurities, fearing that she might not be able to live up to her parents' legacy and expectations, especially her mother's. But over time, Cassie developed into a more confident leader with the aid of her friends.
Despite her brash demeanor, she has a deep sense of morality, refusing to kill opponents except when absolutely necessary. She also shows genuine respect for her elders and masters, as seen while approaching Sub-Zero. She is childhood friends with Jacqui Briggs, who is also part of the team she leads along with Kung Jin and Takeda Takahashi. Like her father, Cassie has shadow abilities, but would not fully master them until her encounter with Shinnok.
She is a stereotypical millennial, sporting many of the most iconic trends and technologies of her generation, including iPods, social media, and digital phones.
[u]Mortal Kombat Story[/u]
Following the defeat of evil Outworld emperor Shao Kahn at the end of the 2011 series reboot, Johnny Cage and his wife Sonya Blade see the birth of their child “Cassandra Carlton Cage”, shortened to "Cassie", but they later divorce. Following in her mother's footsteps, Cassie joins the Special Forces, which uses military training and technology to protect Earthrealm from its enemies. Under Raiden's orders, Cassie leads a task force assembled by her father and composed of a new generation of combatants—Jacqui Briggs, Takeda, and Kung Jin. Sonya does not give Cassie preferential treatment. The team gain experience as they attempt a sneak attack on Sub-Zero's Lin Kuei temple and fail, though the attack is revealed to have been a training exercise set up by Johnny. Sub-Zero tells Cassie and her unit they will fail unless they work together as a team.
Sonya sends the team to Outworld to locate Mileena, who has Shinnok's amulet. Cassie encounters the realm's new ruler Kotal Kahn, who begrudgingly allies with her unit to locate the amulet. The team recovers the amulet, but Kotal has them captured out of distrust and intended to use them to lure Raiden to Earthrealm. When the unit return to Earthrealm, they discover Johnny had been abducted by Shinnok and taken to Raiden's Sky Temple, where the fallen Elder God has corrupted the Jinsei, the source of Earthrealm's life force. After her team gets incapacitated or caught up fighting Shinnok's allies, Cassie faces Shinnok alone. During the battle, she discovers she inherited Johnny's ancient power, which increases her strength, and defeats Shinnok before helping Raiden restore the Jinsei. Following this, Sonya, Johnny, and Cassie happily reunite. In a non-canonical arcade ending, Cassie is assigned to hunt a "soul stealer", who is believed to be the resurrected sorcerer, Shang Tsung. She tracks down the soul-stealer, an elderly man who identifies himself as Shujinko after she beats him to near-death.
Cassie returns in Mortal Kombat 11. Two years after defeating Shinnok, she is promoted to Commander and leads a Special Forces strike team alongside Sonya and Jacqui in assaulting the Netherrealm. While the mission was successful, Sonya gave her life to ensure Cassie and the others escaped safely. Due to a time storm caused by the keeper of time, Kronika, Cassie worked with younger versions of Johnny, Sonya, and Jax to figure out what happened. When the Black Dragon cartel and Cyber Lin Kuei warriors attacked the Special Forces headquarters, Cassie fought to keep her parents' younger selves safe, but Kano ultimately captured them. In light of the attack, Raiden transported Cassie and their remaining allies to Hanzo Hasashi's Fire Gardens to regroup. Having put a tracker on Kano's helicopter, Cassie led the surviving Special Forces members in weakening the Black Dragon and rescuing her parents' younger selves. After Kronika kidnaps Liu Kang, Cassie took part in a joint Earthrealm/Outworld attack on Kronika's keep to rescue him. In her non-canonical arcade ending, after defeating Kronika and attaining her god-like power, Cassie resurrects Sonya so she can retire peacefully and maintains her position as a Special Forces commander instead of becoming the new keeper of time.
