You have been injected with a Code, a one-time device that transmuted you into a regular frame, a biomechanical being composed of placenta and heigus particles. Your new form let's you switch between your human form and your armored form at any time. Placenta is a substance that can regenerate and reshape itself, making regular frames biologically immortal and resistant to damage. Heigus particles are a form of omnipresent background energy that exist in the vacuum of space, and generated by the Code now integrated into you, this energy acts as a hyper efficient fuel source that can be used to power your abilities and weapons. Regular frames also have access to a unique special ability or weapon that reflects their personality and preferences.
The first time you transform into a regular frame, the process is accompanied by a "transmutation light" a powerful beam that stretches into the sky. This phenomenon only happens once and does not occur in subsequent transformations. Initially, regular frames aren't much stronger than baseline humans, resulting in a mechanical skeletal appearance similar to frame disease sufferers. However, over time and by utilizing placenta and heigus particles, they can rapidly grow stronger, and create armor and various objects such as clothing and weaponry, including the infamous EBTG. At their peak, a regular frame has the potential to devastate entire worlds.
All regular frames possess potent physical capabilities, extremely high reflexes, the ability to "digest almost anything" and generally require no breathing or nutrition. They are immune to aging and can only die if their brain is destroyed, their head is severed, or their placenta is depleted before a fatal blow is struck.
By manipulating their own placenta, regular frames can create various shapes and structures, such as blades, shields, spikes, wings, etc. They can also use it to repair or modify other machines or devices that are compatible with placenta. For example, they could create a sword out of their arm, or fix a broken vehicle with their placenta. They can also utilize placenta as jet fuel, granting high-speed boosts, swift battlefield movement, and flight capabilities.
The flow and output of heigus particles in their body can be controlled by regular frames, allowing them to adjust their speed, strength, durability, and temperature. They can also use heigus particles to fire beams, blasts, or bullets from their body or weapon. For example, they could increase their speed to dodge an attack, or fire a heigus beam from their eye. While wearing any level of seal armor emits heigus particles, which can reveals your location, low seal level or no armor can mask this, but makes you more susceptible to attacks from other users.
Regular frames also have the ability to create anti-megastructure bullet (AMB), which is a powerful projectile that can pierce through Megastructure and Semi-megastructure, a near impenetrable material.
During the transformed state regular frames will have a personalized HUD with the same feature as Etherow when armored. The HUD displays the time remaining until activity cutoff (or armor disengagement), remaining heigus particles, seal level warnings, approaching threats, details about the special ability, and more.
