Introduction

The arrival of Android 17 and Android 18 in the Dragon Ball Z saga marked a significant turning point, introducing formidable antagonists with a unique blend of human and machine. Their debut was nothing short of dramatic, setting the stage for intense battles and compelling character arcs.
Initial Presentation of the Android Twins
The twins, Android 17 and Android 18, were introduced as the ultimate creations of Dr. Gero, a scientist obsessed with eliminating Goku.

Android 17, with his rebellious attitude and distinctive green vest, and Android 18, seemingly more composed but equally dangerous, showcased a chilling power dynamic.
Origins and Purpose
Their creation stemmed from Dr. Gero’s desire to exact revenge on Goku for the destruction of the Red Ribbon Army. Dr. Gero, having meticulously studied Goku’s fighting techniques, aimed to build androids that could surpass him.

Transformations and Upgrades
The Androids 17 and 18, unlike Saiyans, do not have a natural progression of power through transformations tied to their biology. Their power levels are, to a large extent, determined by their initial construction and subsequent modifications. While they don’t experience the dramatic visual changes of a Super Saiyan, they do undergo upgrades and power boosts, some more significant than others, which alter their combat effectiveness.
These enhancements often stem from external sources or alterations to their internal systems.
Android 17’s Absorption and Super Android 17
Android 17’s most significant power-up occurs inDragon Ball GT*, where he is absorbed by the Super Android 17 created by Dr. Gero and Dr. Myuu. This fusion results in a substantially more powerful being.
- Absorption: The process of absorption is facilitated by the machine mutant, Super Android 17, and it involves 17’s body being drawn into the other Android’s structure.
- Super Android 17: The resulting being is a fusion, inheriting 17’s personality (albeit somewhat suppressed) and his limitless energy. Super Android 17 is significantly stronger than the original 17. He also possesses the ability to absorb energy attacks, which enhances his power further.
- Visual Changes: The appearance of Super Android 17 is a fusion of both androids. He retains 17’s basic features but gains a more imposing physique. He also has a red and black color scheme.
- Power Boosts: Super Android 17 is powerful enough to overwhelm even Super Saiyan 4 Goku for a time. His power is a combination of 17’s original power, plus the power of the original Android 17, and the added strength of the combined android.
Android 18’s Potential Enhancements
Android 18, while not experiencing a dramatic transformation on par with Super Android 17, is consistently shown to be a formidable fighter. She has not undergone a power-up in the same vein as her brother. Her power level, however, is a point of contention.
- Potential for Improvement: Given her nature as a cyborg, it’s feasible that Android 18 could receive further modifications or upgrades.
- Absorption Potential: Android 18 does not have the absorption capabilities of her brother.
- Circumstances: Her upgrades could involve modifications from Dr. Gero’s research or a collaboration with Capsule Corporation technology.
The following are hypothetical scenarios detailing how the twins might achieve further power-ups:
- Cybernetic Enhancement: Imagine a scenario where Capsule Corporation, possibly through Bulma, offers to upgrade 18’s cybernetic systems. This could involve improved energy absorption, enhanced processing speed, or advanced combat algorithms. This mirrors real-world examples, where technological advancements constantly improve performance in various fields.
- Fusion with a Powerful Being: If 17 and 18 were somehow able to fuse, it would result in a very powerful warrior.
- Cell-Like Absorption: Suppose, for a moment, that the original blueprint for Android 18, designed by Dr. Gero, had been closer to Cell’s, which included the ability to absorb opponents for greater power. This would significantly alter her combat style and increase her strength.
Relationships and Interactions
The Androids, 17 and 18, are not just powerful fighters; they are also complex individuals shaped by their relationships. Their interactions with each other, and with others, have been pivotal in their development and the unfolding of the Dragon Ball saga. Their bonds, forged in the crucible of Dr. Gero’s laboratory and later tested by various conflicts, are a testament to the evolving nature of artificial beings and their capacity for connection.
The Siblings: Android 17 and Android 18
The bond between 17 and 18 is undeniably the most significant relationship for both Androids. They share a deep sibling connection, a shared history of being transformed against their will, and a mutual understanding that transcends their initial programming.Their relationship is a blend of loyalty, protectiveness, and, at times, playful rivalry. They frequently display a united front, supporting each other in battles and decisions.
This solidarity is particularly evident in their shared disdain for Dr. Gero and their initial goals. However, as the series progresses, their relationship deepens, marked by personal growth and mutual respect. For instance, Android 18’s concern for 17’s well-being during the Cell Games demonstrates the depth of their familial affection.
Interactions with Other Characters
Beyond their sibling bond, the Androids interact with various characters, each interaction influencing their choices and shaping their personalities. These interactions are key to understanding their motivations and their growth throughout the series.
- Cell: Cell’s primary objective was to absorb Androids 17 and 18 to achieve his perfect form. This dynamic is one of conflict and survival. Initially, 17 and 18 view Cell as a threat, leading to battles and attempts to evade him. This external pressure forces them to make crucial decisions, with 18 ultimately choosing to sacrifice herself to prevent Cell from reaching his final form, showcasing a complex interplay of fear, defiance, and, ultimately, self-sacrifice.
- Goku: Goku’s presence represents a challenge and an opportunity. While they are initially programmed to destroy Goku, their encounters shift their perspective. Android 17, in particular, displays a grudging respect for Goku’s strength and determination. The later interactions in Dragon Ball Super, where 17 assists Goku in the Tournament of Power, demonstrate a transformation from adversaries to allies, driven by shared goals and a newfound respect.
- Krillin: Krillin’s relationship with Android 18 is transformative. Krillin’s kindness and unwavering belief in 18’s inherent goodness gradually soften her hardened exterior. Their bond develops into a loving relationship, influencing 18 to embrace a more human existence. This relationship underscores the power of compassion and acceptance. It changes 18’s priorities, and the birth of their daughter, Marron, cements her transition.
Impact of Relationships on Actions and Decisions
The relationships of 17 and 18 are not merely incidental; they are fundamental to their character arcs. The influence of these relationships is a driving force behind their actions and decisions.For example, Android 18’s choice to sacrifice herself to prevent Cell from absorbing her is a direct consequence of her growing affection for Krillin and her evolving sense of morality.
This selfless act highlights the profound impact of Krillin’s love and her desire to protect those she cares about. Android 17’s transformation from a destructive force to a protector of nature in Dragon Ball Super is influenced by his sister’s influence and his own experiences. This demonstrates how relationships can reshape the very core of a being, even one created artificially.
