Cybertronian Traits
Cybertronians are a race of living machines which can disguise themselves as flesh-and-blood beasts.
Ability Score Increase. Your Constitution score increases by 2.
Age. Cybertronians are physically mature from the moment they come online. They are considered adults after a few decades and can live for over 500 years.
Alignment. Cybertronians are a diverse people with many different worldviews. Those who identify as Maximals often hew toward good while those who identify as Predacons are often inclined towards evil, but exceptions exist for both groups.
Size. Cybertronians range from five feet tall to just under eight feet in their natural forms. Your size is Medium.
Speed. Your base walking speed is 30 feet.
Cyborg Nature. Your creature type is both construct and beast.
Lightning Vulnerability. You are vulnerable to lightning damage while in your natural form.
More Than Meets the Eye. You gain proficiency with the Deception skill.
Natural Armor. Your metal body has built-in armor plating. It prevents you from wearing most forms of armor, but also means you don’t need it. Your base AC is 13 plus your Dexterity modifier (maximum 3). You can wield a shield and still gain this benefit.
Beast Mode. You can spend a minute scanning a Small or Medium beast that is CR 1/2 or less. This beast becomes your beast mode. You can use your action to transform into your beast mode or revert to your natural form. While you are in beast mode, the following rules apply:

Your movement speed(s), senses, and actions are replaced by those of the beast. If you make an attack with the beast’s natural weapons, the attack roll uses your proficiency bonus and Strength modifier, and the damage roll uses your Strength modifier. Your statistics are otherwise unchanged.
You gain any special features that the beast possesses, such as a giant wolf spider’s Web Sense and Web Walker features.
You retain the ability to speak, but you cannot cast spells that require material or somatic components.
Any gear you are wearing or carrying merges with your beast mode. Equipment that merges with your beast mode has no effect until you leave beast mode.
You revert to your natural form if you fall unconscious or die while in beast mode.
You can change your beast mode to a different beast by repeating the scanning process. Once you have done so, you cannot change your beast mode again until you finish a long rest.
Languages. You can speak, read, and write Common and one other language of your choice.
Racial Feats
Aberrant Spark
Prerequisites: Cybertronian

Your Spark has unusual properties which make it difficult to extinguish. You gain the following benefits:

You regain 1 hit point at the start of each of your turns if you have less than half your hit points remaining and have at least 1 hit point.
You have advantage on death saving throws.
As a bonus action, you can spend one of your Hit Dice to regain hit points as if you had taken a short rest. Once you have used this feature, you cannot use it again until you finish a long rest.
Autotransformer
Prerequisites: Cybertronian

Through repeated practice, you have learned how to transform with incredible speed. You gain the following benefits:

Your Dexterity score increases by 1, to a maximum of 20.
You can transform into your beast mode using a bonus action instead of an action. You can revert to your normal form using a bonus action as well.
When you transform into your beast mode or revert to your normal form, you have advantage on the first attack roll you make before the end of the current turn.
Load-bearer
Prerequisites: Cybertronian

You have trained yourself to tolerate great strain and heavy loads, allowing you to assume forms larger than yourself. You gain the following benefits:

Your Strength or Constitution score increases by 1, to a maximum of 20.
When you change your beast mode, you can choose a Large, Medium or Small beast of CR 1 or less for your new form.
In your natural form, you count as one size larger when determining your carrying capacity and the weight you can push, drag, or lift.
When you transform into a Large beast mode, you gain temporary hit points equal to your level plus your Constitution modifier. These temporary hit points last for 1 hour or until you revert to your normal form. You can only gain this benefit once per short or long rest.
Transmetal
Prerequisites: Cybertronian

You have been drastically altered through self-modification or exposure to strange energies, causing your natural form to take on organic qualities and your beast mode to appear overtly mechanical. You gain the following benefits:

You are no longer vulnerable to lightning damage while in your natural form.
When you transform into your beast mode, you can use any ranged weapons that you were carrying in your natural form. These weapons are considered part of your body and you do not need a hand free to use them. They otherwise follow the normal rules for ranged attacks.
While in beast mode, you can use a bonus action to sprout vehicular components such as jet thrusters or a set of wheels. These components either grant you a flying speed of 30 feet, or increase one of your beast mode's existing movement speeds by 30 feet. You choose which when you gain this feat.
