A Brief History of the Cybertronian Civil War

4,000,000 BCE – 2006 CE

By Devastron

Roughly four million years ago, the Cybertronian Civil War began when the High Council ruling Cybertron attempted to have Megatron assassinated for prying too deeply into their secrets. Enraged, the popular and ruthless Megatron soon rose to lead the Decepticons in a war against the Autobots, commanded by Optimus Prime. Amid the escalating war, Megatron pursued a hidden goal — to reactivate Cybertron’s planetary engines and transform the planet into a mobile Warworld. This Warworld would allow Megatron to establish a galaxy-spanning Decepticon Empire. However, Optimus Prime and the Autobots thwarted his plan. The destruction of the engines beneath Cybertron left the city of Kalis in a devastated state.

As the war dragged on, both factions recklessly depleted Cybertron’s resources. After 300,000 years of conflict, the planet faced imminent energy collapse. With no viable path forward, both sides agreed to enter voluntary stasis lock, leaving behind "contingency units" — specialist Transformers who would periodically awaken to assess the state of the planet and monitor their enemies. For nearly 3.7 million years, the planet healed while the Transformers slept.

Around 100,000 BCE, these units observed that Cybertron’s core energy had stabilized. Both factions awoke and began rebuilding power infrastructure, including solar collectors and Tyrest’s Collector Array Fields. Then, predictably, the war reignited. With access to energon and enhanced tech, the battles intensified.

Cybertron’s energy reserves eventually began to decline once more. The warning signs weren’t as catastrophic as before, but they were troubling. Decepticon scientists were the first to detect them and began researching alternate energy sources. The Autobots soon followed. The Decepticons focused on exploiting a resource-rich planet referenced in a long-forgotten planetary survey.

While most Autobots found the idea of exploiting another world abhorrent, they recognized the desperate circumstances. They hesitated, hoping for a technological breakthrough. The Decepticons, less patient, prepared to act on their old survey data.

Before Megatron could execute his plan, the Autobots launched massive counteroffensives across Cybertron. Decepticon strongholds like Altihex fell to the Autobot advance. Heavy losses afflicted both sides, but the Decepticons were driven into a defensive stance. The Autobots, weary yet determined, pressed forward in a brutal war of attrition.

By 2006 CE on Earth, Decepticon forces in Polyhex led by Shockwave and Starscream prepared to defend against an assault from Iacon and the Tagan Heights. Thunderwing rallied Tyrest's forces to repel Fortress Maximus’ advance from Nova Cronum. The impending battle loomed as one of the largest since the Great Shutdown.

The battle began swiftly. Fortress Maximus led his troops into the Killzone between Nova Cronum and Polyhex. The Decepticons, though outnumbered, mounted fierce resistance. Eventually, Shockwave himself entered the fray, deploying the last of his reserves in a desperate flank attack.

Shockwave and Fortress Maximus clashed in a brutal fight, neither able to gain the upper hand. Just as Maximus prepared to finish the Decepticon commander, Megatron arrived and incapacitated Maximus with his fusion cannon. Megatron’s intervention turned the tide — until Optimus Prime arrived with reinforcements. The two leaders fought for the first time in a millennium.

The battle reached its climax when Optimus Prime summoned the newly completed Omega Supreme. His overwhelming strength and firepower tipped the battle decisively. With Omega Supreme’s support, Prime forced a ceasefire and opened negotiations. The two commanders agreed to meet on Cybertron’s first moon, while Omega Supreme remained stationed at Polyhex.

Unbeknownst to the Autobots, the Decepticons had just completed a new army, modeled after a prototype seen in the Tagan Heights. As Megatron prepares his next move, a long-lost planetary survey team returns to Cybertron…

Somebody asked elsewhere how to play the RPG. This seems like the proper place to answer. What follows isn’t a mandatory checklist, but rather a guideline to help you get the hang of it. This type of RPG is more like an interactive fanfic — we don’t use dice to determine outcomes, so we ask that you play responsibly.

First, read the rules. It helps to think about why those rules exist — understanding their purpose gives you insight into the RPG’s goals. The most important rule? Don’t control any character but your own. New players often overlook this.

Create or choose a character. You can have more than one, but it’s best to start with one and add more later. Check the "List your characters here!" topic to make sure your character (or name) isn’t already taken. If you’re choosing a G1 character or similar, it’s wise to ask in that topic or in a PM to the mods whether the character is available or has RPG history. Fan-made characters generally avoid these issues.

Fan-made and Japanese series characters must be approved by an RPG mod before use.

Write a character summary in the appropriate thread:

• Decepticons → Decepticon Character Profiles
• Autobots → Autobot Character Profiles
• Others (e.g., humans) → Non-Affiliated Character Profiles

Don’t forget to list your characters in the "Role Call!" thread.

Stats aren’t as critical here as they are in tabletop RPGs, but you should define your character’s main traits, strengths, and weaknesses. This helps others know how to interact with your character and keeps the game coherent.

A Description of Stats

Strength: Lifting capacity and melee damage. 5–6 is average. 10 is reserved for the most powerful, like combiners.

Intelligence: Mental ability, creativity, problem-solving. 5–6 is typical; 9+ is for true geniuses. Don’t go too low or your character may be limited.

Dexterity: Agility, reflexes, balance. High dexterity implies fast reactions. Large or armored characters typically won’t score high here.

Speed: Travel and reaction speed in your fastest mode. 10 is for space-capable fliers. Provide mph/kph in your character’s profile.

Endurance: How much damage your character can take. 10 is near-invulnerability. 5–7 is typical for standard armor.

Courage: How your character handles fear. 10 means reckless; 1 means easily frightened.

Firepower: Ranged weapon strength. A 10 is for massive firepower or special cases like Megatron.

Accuracy: Ranged hit precision. 7+ is highly accurate. 10 is rare — reserved for sharpshooters like Sureshot.

Melee: Skill in hand-to-hand combat. Includes weapon use and martial arts. 6 is average; 8+ means expert fighter.

Tech Skill: Technical and scientific expertise. Medics and engineers should score higher here.

Charisma: Influence and leadership. 10 implies natural leadership (e.g., Optimus Prime). Even bullies need some charisma to be effective.

Rank: Hierarchical standing. Assigned by mods after approval. Most characters begin at a low rank.

If someone tells you your characters are overpowered or don’t fit the continuity, don’t take it personally. It’s not criticism for its own sake — it’s about maintaining quality and consistency. Mistakes happen. Treat feedback as constructive, not insulting.

Once your character is ready, it’s time to begin. If you’re not sure where to start, ask in the thread or message a mod. Reading a few recent threads helps, too. The RPG is usually flexible enough that you can insert your character naturally. You could also ask someone (like a faction leader) to help introduce your character, or create your own thread — just note that others might not join in right away.

Early on, expect to be ignored. There’s a lot going on, and players have many characters. Don’t take it personally. Instead, engage directly with someone else's character or react to what’s happening in the scene. You’ll likely get a better response.

Interaction is the point. It’s collaborative storytelling — like writing a fanfic with dozens of authors. Don’t get too attached to your own storyline; be flexible and roll with what’s happening. Focus on character personalities and respond organically.

Conflict will happen — it’s inevitable. You can resolve it in-character through posts, or out-of-character by messaging the other player. Some storylines are agreed upon in advance (e.g., "Can you pretend not to notice when Windbreaker uses a chemical weapon?"). Many big story arcs work this way.

What’s the point? That’s up to you. Some enjoy character development, some love epic battles, and others prefer world-building. It’s all part of the shared universe we’re creating together.

About Infighting

Given the nature of the Decepticons, some internal conflict is expected. These skirmishes often resemble sparring — they’re tests, not real threats. Sometimes they’re planned, other times spontaneous. Players should not overreact, and communication is key. Always keep RP consensual.

Competition is also common — characters vying for position or recognition. That’s fine, as long as it doesn’t cross into betrayal. The team’s advancement should always come first.

Serious harm or assassination is rare and typically reserved for threats to the whole team. These actions usually require mod approval. Don’t challenge superiors lightly — it can lead to in-game consequences.

IC Actions & Consequences

Action → Possible Consequences

• Insulting someone more powerful → Beating or death
• Infiltrating a base or fighting to the end → Capture, interrogation, execution
• Disobeying orders → Prison, exile, execution, defection
• Going insane → Mindwipe, reprogramming, institutionalization, execution

This guide provides a reference for the relative heights of Transformers characters. Starscream, for example, stands at 32 feet — taller than the average Transformer, which is roughly 25 feet tall.

The heights are listed in feet. To convert to meters, multiply by 0.305. For example:

• 72 ft ≈ 22.0 m
• 66 ft = 20.1 m
• 60 ft = 18.3 m
• 54 ft = 16.4 m
• 48 ft = 14.6 m
• 42 ft = 12.8 m
• 36 ft ≈ 11.0 m
• 30 ft = 9.1 m
• 24 ft = 7.3 m
• 18 ft = 5.5 m
• 12 ft = 3.6 m
• 6 ft = 1.83 m
