Now, I know that Kamen Rider Drive is a bit of an old series, at this point. But, I have been wondering, "If Kamen Rider Drive were to come back, what could additional forms be?"

First of all, let's think about what the new forms could be based upon. To think about that, we need to go back and think "What have Shift Cars, Signal Bikes, and/or Viral Cores have been based upon in the past?" So, first Shift Cars. This won't include Shift Tridoron, Shift Ride Crosser, Shift Heartron, or the Legend Rider Shift Cars.
Shift Speed: Based upon a Sports Car
Shift Wild: Based upon a Dune Buggy
Shift Technic: Based upon a Garbage Truck
Shift Deadheat: Based upon a Motorcycle and Sidecar
Shift Formula: Based upon a Formula 1 Car
Shift High Speed: Based upon a Luxurious Sports Car
Shift Next Special: Based upon a Futuristic Car
Shift Max Flare: Based upon a Flaming Hotrod
Shift Funky Spike: Based upon a Spiky Hotrod
Shift Midnight Shadow: Based upon a Ninja Hotrod
Shift Justice Hunter: Based upon a Police Car
Shift Dream Vegas: Based upon a Limousine
Shift Dimensional Cab: Based upon a Taxicab
Shift Massive Monster: Based upon a Monster Truck
Shift Rumble Dump: Based upon a Dump Truck
Shift Mad Doctor: Based upon an Ambulance
Shift Hooking Wrecker: Based upon a Tow Truck
Shift Burning Solar: Based upon a Solar Car
Shift Colorful Commercial: Based upon a Mobile Billboard
Shift Spin Mixer: Based upon a Concrete Mixer
Shift Fire Braver: Based upon a Fire Engine
Shift Rolling Gravity: Based upon a Road Roller (Insert obvious JoJo Reference here)
Shift Deco Traveller: Based upon a Dekotora
Shift Road Winter: Based upon an Ice Resurfacer (Zamboni)
Shift Amazing Circus: Based upon a Clown Car
Shift Mantern F01: Based upon a Gas Refuelling Tank
Shift Jacky F02: Based upon a Floor Jack
Shift Sparner F03: Based upon a Combination Wrench
Shift Mega Max Flare: Based upon a Flaming Hotrod
Shift Next Builder: Based upon a Futuristic Garbage Truck
Shift Next Deco Traveller: Based upon a Futuristic Dekotora
Shift Next Hunter: Based upon a Futuristic Police Car

Next to cover the Signal Bikes. This will not be including Shift Deadheat, Signal Mach, Signal Chaser, or any of the Legend Rider Signal Bikes
Signal Magarl (To Turn/Bend): Based upon a Dirt Bike
Signal Kikern (Danger): Based upon a Custom Bike
Signal Tomarle (To Stop): Based upon a Sports Bike
Signal Kaksarn (Scatter/Diffusion): Based upon an American-style Bike

Finally, the Viral Cores. To simplify this, each of the different types of normal Viral Cores will be given 1 category.
Cobra Viral Core/Chaser Cobra Viral Core/Neo Cobra Viral Core: Based upon a Cobra
Bat Viral Core/Chaser Bat Viral Core/Neo Bat Viral Core: Based upon a Bat
Spider Viral Core/Chaser Spider Viral Core/Neo Spider Viral Core: Based upon a Spider
Lupin Blade Viral Core: Based upon an Older-Style Car with a blade on the back
Rhino Super Viral Core: Based upon a Rhino

So, I know that Malunis has created Shift Car, Viral Core, or Signal Bike-like things based upon ATVs called Off Roaders, but I think that we should work with the other collectable Henshin Vehicles Maybe a Shift Car based upon a Pick-up Truck could work? A Pickup Truck is designed to carry large amounts of stuff. So, let's make a whole group of Shift Cars designed mainly to be strong enough to tank blows from larger things (like the Giger Mecha from Kamen Rider Zero-One). It could require Drive to put your all into using its abilities to use it. Because of this, this form is particularly taxing for the user's stamina. Overall, this form is less for Weaponry and more for physical kicks and punches. However, there is a Weapon for this form; a hammer. Because the Sword has a Steering Wheel and the Gun has a Door, this particular weapon could have a Stick-Shift, a Gas-Pedal, or an Engine motif. The Pickup Truck-based Shift Car could have some of its own similar Shift Cars which are all about making the use of this a bit easier and less taxing on Drive's Stamina. Here are some possibilities:
Shift Relaxing Vacation: Based upon an RV; Makes the use of it a bit less taxing on the user's stamina
Shift ? (Not sure about this guys particular name): Based upon a Tanker Truck; Allows for the Kicks and punches to be fired up and takes a little of the strain off of Drive. However, the Tanker can only work for a couple minutes, so he has to transition to another Shift Car to allow for it to recharge
Shift ?: Based upon a Horse Transport; Makes his kicking and punching a lot faster (just a bit below Shift Speed)
Shift ? Cart: Based upon a Golf Cart (a bit out-of-left field); Allows for you to scan for weak spots so you can aim your attacks for them (Like a golfer)
Shift Peaceable Van: Based upon a Van (Like a Volkswagen Bus); Has a strange aura that can make even the most violent individual pretty much a total pacifist (Sort of like the Progrise Hopper Blade)
Shift ?: Based upon a Duck Vehicle (Remember the beginning of the final season of Fetch! with Ruff Ruffman?); Gives him the ability to move on water
Each of them has a different personality. The Pickup Truck is a strong, but kind-hearted Shift Car. Relaxing Vacation has a personality of a vacationer, totally chill. The Tanker Truck is a bit on the Gruff, No-Nonsense Side. The Horse Transport is basically a Texan. The Golf Cart is very much a guy who would prefer his regular job of fishing golf balls from Water Hazards to battling. But he does admire Shinnosuke. The Golf Cart wants to teach him how to play golf, some day. Peaceable Van is a Hippie. Really chill and everything. He wants people to chill out, man. Use less Fossil Fuels. Pollute less. Take care of the environment. The Duck Vehicle is a pirate. Arr. Avast! He regularly steals from the Roidmudes (and sometimes from his fellow Shift Cars, but that's just in fun pranks).
Another group could all work with the Shift Fruits Shift Car. They could all be based upon Lockseeds Gaim has been associated with: The Pine(apple) Lockseed and the Ichigo (Strawberry) Lockseed. This should be easy to make.
Meanwhile, next, I'll cover Viral Cores as I don't really have any ideas for Signal Bikes, but I do have ideas for Viral Cores. The first Viral Core idea is based upon a Buzzard/Vulture. The Second is based upon a Scorpion. And the Third is based upon a Jaguar. These are all animals also associated with evil or death.
