The LimitBreaker Project

Summary
The LimitBreaker Project is a mission that was carried out in a Top Secret Red Ribbon Army facility somewhere within the regions of West City. It was a plan to try and kill Goku after realising he became to powerful to stop by any human means. To do this, they were to send one of their top soldiers to Planet Namek (Goku's next destination) in a suicide mission to blow up the planet with the hopes of Goku dying in the ensuing explosion. The subject chose for this mission was Ayana Eke.

In reality however, the purpose of this plan was to birth a fighter able to become one of Yurmister's 12 Disciples. Within this, Android #21 was attempting to create an army of warriors that could defeat Yurmister.

Overview
Ayana Eke (officially dubbed as "#147") was made by the Red Ribbon army being the first successful attempt of creating a biological Saiyan android. She was created using the remnants of the DNA of Bardock, Gine and Goku on the spaceship the latter crash landed on. However, due to the small quantity of DNA, they had to used Zema Eke as a carrier as well as the aid of Towa and Android 21 as additional genetic material.

During this period there was a time distortion created by Towa. She also had plans other than the one Yurmister wanted, being to produce a powerful "slave" to revive the demon realm so she had taken Android #21 to personally train this new warrior. Android 21 gave her an artificial right arm, stomach and heart (used as a self sustaining energy core, no need to eat thereby increasing efficiency). As Ayana was a successful result, she frequently experimented on her, making her go through physical and psychological torture until she would become an obedient killing machine. Eventually, due to the manipulation of her S-Cells and the intense anger she felt towards her captors, Ayana was able to achieve Super Saiyan. She had then attempted to overpower Android #21 but failed as she was on a completely different level of strength. So as to prevent an incident like this, Ayana was forced to wear an "I-Circlet", a device that would both inhibit her Super Saiyan form but also make her more subservient towards the Red Ribbon. Despite Ayana resisting and making multiple escape attempts, she was unable to remove herself from the clutches of Android #21. It should also be noted that due the mental strain and torture on her brain, accompanied with the brainwashing of the Red Ribbon, Ayana end up believing her name to be Zema, her mother's name, as she engraved it on her cell wall to remember what little she had left of her former life.

They used her in order to eliminate Goku by detonating Planet Namek whilst he was on it (a cover up plan for the RR guards as they were unaware of the true grandeur of the plan). The plan was known as The LimitBreaker Project. They used a replica version of the Saiyan pod in order to send her to Planet Namek, as well as stealing the blueprints of the ship that Dr. Briefs had made for Goku. When "Zema" had arrived, she began their plan, setting off explosions in weak areas of the planet. However, she was briefly stopped by Nail who, despite his best efforts, couldn't defeat Zema and was left for dead.

She was soon to be encountered by another roadblock however, as Frieza's ship prevented Zema from enacting her programming to 100% completion as it had a barrier preventing her from destroying it from the outside. In an attempt to circumvent this, she went aboard the ship to try and investigate and destroy it from the inside. What the Red Ribbon Army failed to take into account was the fact that in order to try and assimilate into the Frieza Force Zema would have to remove the I-Circlet, which caused the Red Ribbon's grip on Zema's mind to diminish. So one could argue that her obedience was simultaneously a benefit and detriment of the Red Ribbon. This would soon start to cause issues as this wasn't part of her original 'programming' resulting in unwanted side-effects which would be highlighted when she eventually went to Hell for the first time.

On Namek, Zema had: After joining with Cooler (and taking Dodoria and Jeice as slaves for the cause) Zema had successfully detonated Namek, killing Goku in the process. Following this, Cooler and Zema spent a year taking over planets and civilisations previously held by Frieza. They then spent the better part of 6 months ruling the galaxy until they decide to set their next destination to Earth. During this time, Jeice offs himself due the intense torture that befell him from Zema, as well as longing to see Captain Ginyu and the Ginyu Force once more. The last remaining Frieza Force ship had intersected them and landed on Earth before them.
