Reply to review from Maroon567: Grimgerde, not sure if it will be later, and I would say it can affect their personality, hell, they might have a second personality because of it.

While this may seem strange, I'm using a custom built Grimgerde I found online as the base, while this may seem cheap, there is a reason for this. There aren't just a lot of actual PD mobile suits to choose from, so most of the ace suits would be custom built units found online and modified by me.

I do not own RWBY, but I do own this modified version of this mobile suit as the original one belongs to Yukki, the modeler.

V08-1228 Grimgerde "Crimson Inheritor"

Appearance

-Base Form: Based on the custom built Grimgerde built by Yukki. The head mostly remains the same, but new parts have been added to it along with the removal of any decals. They include 75mm CIWS on the sides of the head, a new faceplate that includes dual silver eyes and a mouth guard, and Ruby's symbol on the sides of the helmet. The upper torso was given lighter, but weaker armor along with a pair of "Slash Harkens" located near the sections where the arms meet the body and the lower torso was given the ability to make 360 degree turns. The arms were replaced with arms similar to the Type-97 Fubuki TSF from the Muv Luv Alternative series, but there large boosters on the side shoulders that were similar to the Type-04 Shiranui TSF. The arms removed the Valkyrja shields and blades with arm sheaths on the sides that hold a Valkyrja knife. The side waists mount a pair of 120mm SMGs with the back waist mounting an experimental Jump Unit. The legs remain the same other than it was given drill in the knees and hidden blade compartments inside the legs themselves. The back only mounts a pair of grappling guns near the back shoulder. Color is dark red with silver outlines.

-"White Rose": Using the same basis as "Crimson Inheritor", the head does have a new faceplate that includes silver eyes and a mouth guard, but there is no symbol or 75mm CIWS located anywhere. The upper torso has the cockpit moved the back, making a lump on the back, the mid-torso section has no cover, but can make 360 degree turns. The arms are the same with the shoulders mounting 32-tube micro missile launchers that are inside and pop out when in use. The arms have armor plating that full covers the weak spots while retaining their ability to mount the Valkyrja shields and blades. The side waists have Flash Boosters while the back waist mounts a custom Assault Cannon. The legs only have the hidden blade compartment inside the legs as an upgrade other than weaker, but lighter armor. The back has the cockpit in a hunchback like position and the only weapons added on were a pair of different Assault Cannons near the shoulder back. Color is white with dark red outlines.

Armaments

-Crescent Rose: A mobile suit sized version of Ruby's weapon, it is a combination of a scythe and a high caliber sniper rifle. It has different 3 modes, storage is its basic mode in which it takes a form of a box for Ruby to carry, rifle mode converts the box into a bolt-action rifle that is used to shoot targets from afar, and scythe mode converts the box into a full length scythe that is used for close to medium range combat, it can also double as a long barrel sniper rifle as the rifle's barrel is at the tip. The recoil of the rifle is so powerful that it would knock the person back, but Ruby uses this to her advantage as she uses the recoil of the rifle to propel herself. The scythe can switch into a war scythe, which is usually used more as a spear. Ruby can load different types of Dust ammo for her weapon, ranging from fire, ice, to even gravity. It is noted that the scythe is made from the same material used in in Valkyrja blades, allowing the weapon to damage Nano-Laminated Armor.

-75mm CIWS: Mounted on the sides of the head for "Crimson Inheritor", they are mostly used to destroy lightly armored targets.

-"Slash Harkens": (They are the Slash Harkens used for the Knightmares in Code Geass.) Located near the sections where the arms meet the body, they are basically wire guided projectiles that can be used for offensive or defensive moves. Ruby uses these weapons to get up to targets up close or get to cover quickly.

-Valkyrja Knife: (Design is the same as the Type-65 PB Knife used in Muv Luv Alternative) Stored the arm sheaths, they are mostly last resort weapons, but can be used as an actual weapon as it can damage Nano-Laminated Armor.

-120mm SMGs: Mounted on the side waists, they are usually dual wielded and are lightweight, allowing more mobility. These guns exchange accuracy in far range for high rate of fire. If used, extra magazines are mounted on the side foot for quick reloads.

-Drills: Located inside the kneecaps, the drills are capable to penetrate Nano-Laminate Armor, but this weapon can be used properly for attacks from below.

-Long Sword: Located in front of the leg for both "Crimson Inheritor" and "White Rose", this weapon is used properly when it is fully unfolded, in which the unit has to fly for a short time to use it. The blades have sharp edges on both sides and are coated with Nano-Laminate Armor, allowing for a clean cut. The unit has to swing the legs to use this strange weapon.

-Grappling Guns: Mounted on near the back shoulder, the hooks are coated with Nano-Laminate, meaning they can pierce MS armor, but if that doesn't work, the hooks attach themselves to the target by using a magnetic lock. However, if the enemy is skilled enough, they can grab the wire and swing around the suit that fired the hook.

-32-Tube Micro Missile Pod: Located inside the shoulder and pop out when in use for "White Rose", they fire smaller, weaker missiles as they save space for carrying weapons.

-Valkyrja Shield: Mounted on the forearms of "White Rose", they are part of the Grimgerde's basic armor and stores one Valkyrja Blade inside.

-Valkyrja Sword: Located inside the Valkyrja Shield for "White Rose", they can be held with the hand or be used from the shield by rotating forward. The metal used in the sword is tougher than the material used in Gundam Frames. The blades can damage Nano-Laminate Armor, but it is recommended to strike weak spots like open joints and gaps between armor.

-110m Valkyrja Rifle: A standard range weapon for all Valkyrja units and 2 are used for "White Rose", it is lightweight in design, which allows quick maneuverability. However, like all regular range weapons, they are mostly ineffective against Nano-Laminate Armor, but the rifle can be equipped with a drum magazine for higher ammunition. They can be mounted on the Valkyrja Shield if need and can still fire while mounted on the shield.

-Custom Assault Cannon: (Design is the same as the Type-87 Support Assault Cannon from Muv Luv Alternative.) Mounted on the back waist, it uses an extended barrel over a 36mm chaingun barrel to increase accuracy and penetrating power with a scope and is reserved mostly to sniper personal. The weapon can be fired in full auto or single shot, but most pilots choose single shot for obvious reasons.

-Assault Cannons: (Design is the same as the Type-87 Assault Cannon from Muv Luv Alternative.) Carried by sub arms mounted near the back shoulders for "White Rose". It is a combination of 2 types of guns, a 36mm chaingun makes up the base with a removable 120mm cannon on the top front. The 36mm rounds are mostly ineffective against Nano-Laminated Armor, but the 120mm rounds will surely put a dent in the armor. The 36mm chaingun carries 2000 rounds per magazine with 6 rounds for the 120mm cannon. The weapon is surprisingly light and easy to handle.

Special Equipment and Features

-Ahab Dust Reactor: The main power source the unit, it uses the newfound Ahab Dust to generate an unlimited amount of energy. The reactor will give off Ahab particles, which can be used for artificial gravity and inertial control, removing the needs for a Gravity Dust generator. However, it is noted that the Ahab particles also give off Ahab waves, which can disrupt radio waves, communications, and guided weapons. The 4 kingdoms forbid the use of these reactors in the cities as it would disable the entire city. It is noted that all reactors generate their unique frequency, allowing for easy identification.

-Nano-Laminate Armor: The main protection for all mobile suits, it uses the Ahab particles and waves generated by their own power source to give them the protection. Most range weapons are fairly useless against them as it only shaves small pieces of it. However, melee weapons are the main weakness of this armor and also while it can shrug off range weapons, if the armor takes too many shots from range weapons, the armor will break down and leave the suit open for attack. It is noted that Nano-Laminate Armor is usually painted on, allowing for quick repairs and different colored paints can be added on for the right price, but it is unknown if the different paint will change the performance of the suit. Noted that all forms of energy-based attacks are ineffective against this armor.

-"Aura" Nano-Laminate Armor: A variant of the Nano-Laminate Armor, it uses a special generator that connects to a person's Aura if unlocked and it acts as a second layer should the Nano-Laminate Armor be breached. However, the downside for this armor is that it takes more Aura than regular to create the field.

-High Sensitivity Sensor: Located above the head, it is used to analyze a target's data.

-Half-Metal Chassis: A special type of material that is used widely on mobile suits and warships that use Ahab Dust Reactors, it resists the jamming effects of the reactors and if large amounts are used, it can prevent the reactor from being detected.

-Advanced Support Intelligence (A.S.I.): Located inside the cockpit for "Crimson Inheritor", it is a specialized AI designed to help control the complex controls of the Grimgerde, it can help the pilot pull off complex maneuvers and moves. The pilot can even use the AI to control the suit itself and it shows that it can go toe to toe with 3 regular Graze pilots. However, there is one fatal flaw to this AI, it's that it has a nasty habit of taking over the suit by force if it deems the situation too dangerous. It is noted that the unit's optics glow green when in use or control.

-Sniper Support: Located inside the cockpit for both machines, the pilot uses a large sniper-like mechanism to fire their sniper shots that are usually hard to do when in long range. (Works like how Lockon Stratos fires when he is in sniper mode.)

-Flash Boosters Type Omni: Mounted on the shoulders "Crimson Inheritor" and on the side waists for "White Rose", this allows the pilot to make faster dodges or reflexes, the wings can also move freely around the shoulder and side legs to make sure the Flash Boosters can save the pilot's life.

-Experimental Dust Jump Unit: (Design is the same as the jump unit used by the Type-94 Shiranui TSF from Muv Luv Alternative.) Mounted on the back waist for "Crimson Inheritor", it uses a mixture of unstable Dust to allow the unit to achieve high speeds. The unit can also allow the unit to fly for a short time, but only on mode can be active during a time. "Jet" mode for speed and "Rocket" mode of flight. Ruby can activate her semblance, which is speed, to make the boosters go into overdrive, increasing the speed 3 times. For some reason, rose petals come out of the engine when semblance is used. The only problem with this engine is that Ruby cannot use it all the time, if used continuously; the engine would overload and explode. A common problem among the many different jump units of this series is that it requires maintenance every time it is sortied. The jump unit can be purged if needed and it can also boost in all directions, making it very adaptable.

-Sub Arms: Located on the back for "White Rose", they are mostly used to carry extra weapons into the battlefield, but this one was modified so that it can fire the carried weapon automatically or by the pilot.

History

First developed by the Vale military during the Calamity War, this unit was given to the Rose family, who are royal guards to the King of Vale. There is little known about the machine during the Calamity War other than accounts saying it was an angel on the battlefield. The unit was locked in their family vault after the end of the war, but was reactivated by Summer Rose for the machine to be her personal unit. The unit was equipped with an unknown black box system with activation requirements unknown. Summer Rose was taking a stroll with the unit and with her young daughter, Ruby inside the cockpit when tragedy struck. The unit was ambushed by 3 Grazes piloted by descendants of some of Mantle's ace pilots. They seek revenge against the Rose family's MS. Summer is forced to fight, but the unit only had the Valkyrja Blades and twin Assault Cannons, so it was difficult one to win. She manages to drop off the young Ruby somewhere she thought was safe, but after destroying 2 of the 3 Grazes, the 3rd one manages to find Ruby and play a hostage situation. Everything was a blur after that as Ruby was knocked out and when she woke up, "White Rose" was lying on its side as the back cockpit was open and when she checked inside, no traces of blood or a body can be seen. Help arrives as they take the machine and Ruby out of the fight, but she believes that her mother is still there and begged to go find her. Years later, Ruby inherits "White Rose" and renames it to "Crimson Inheritor". She gets a free pass to Beacon by Ozpin, but deep in her mind, she wants to find answers to where her mother has gone.

Next Unit: Weiss Schnee's Mobile Suit

Now I made Ruby kinda like Yang when it comes to searching for her mother, but she is dead serious on finding her mother, even if it kills her.

If you didn't noticed by now, I'm aware of the Tactical Surface Fighters or TSFs from the Muv Luv Alternative series. I'm a fan of the mechs in the series, but not so much for some of the stories and characters. If anyone is interested, I can make a Tactical Surface Fighter Dossier for the RWBY crew if anyone is interested in one.

Notes

-Ruby Rose (Post Disaster): Same scenario and age when she got into Beacon, she's mostly normal, but she is on the search for her mother. She states that since there was no blood or body inside "White Rose", her mother is alive somewhere in the world. This can lead to her downfall as she would take any sorts of information about her mother as to even rumors. She will not stop to find her mother, even if she has to abandon everything else to find her.
