“Konichiwa! I am Doctor Science, and I have had my robots kidnap you and bring you here for one, very important purpose.
Our planet is in grave peril! Lizard Men, fleeing environmental catastrophe on their home planet of Venus, have come to Earth in a fleet of Ark ships and plan to destroy our defenses and venusiform our planet, using a series of ever-more-improbable giant monsters!
The military is helpless! I was laughed out of academia!
Only a group of radical teenagers, with precocious martial arts skills, equipped with skin-tight spandex and giant robots can hope to meet the menace! You are those radical teens, I have the giant robots. Will you answer the call?”
– Doctor Science Phd
Sentai is the name of type of Japanese action series, one that has gone on – in its main form – (with some vague sense of continuity) for a very long time. That longest-running series is what gave its name to the genre as a whole, Supa Sentai Shirizu, along with its huge number of imitators, spin-offs and re-dubs.
You may know the genre from its western form, Power Rangers, or from anime such as Voltron, or G-Force. Personally I always had a soft spot for X-Bomber (Starfleet).
Sentai means ‘task force’ or ‘squadron’, and the genre has some pretty consistent conventions that will probably be familiar to you.
- A skillful team of oddballs.
- Who can transform into superheroes with some unique powers and weapons.
- Who are colour-coded.
- Who often have mecha, or transforming vehicles.
- Which can often combine into one giant robot.
It’s high camp, high adventure, full of imaginative strangeness, monsters, giants and drama. The sheer creative chaos of the whole thing is inspiring, energetic, and a lot of fun. Well worth playing in RPGs.
I’m going to suggest that you base your game off Daikaiju Die, which, while it is more geared towards Pacific Rim or Giant Robo style games, is more than capable of standing in for Sentai, and scaling from teenage martial artists, to super-suit wearers, to mecha drivers, to giant robot combat.
There’s a few changes that need to be made, however.

New Skill
Synergy replaces the Interface Skill found in Daikaiju Die. Rather than complex systems of rolling, Synergy just provides you, flat out, with a number of additional FATE points that you can tap into, while you’re occupying your personal or combined mecha.
Mecha and Skills
In Daikaiju Die, and in this game-sketch, Mecha have their own skills, as they have a sort of personality and psychic connection with their driver. However, driver and mecha’s mutual skill interrelate with each other.
- When driving a Mecha, you use your FATE points (and Synergy) to empower its stents and so forth.
- If a character’s skill is higher than the Mecha’s skill, then that skill counts as one higher.
- If the character’s skill is lower, then the Mecha’s skill is reduced by one.
- When Mecha combine, you take the average of the Mecha skills (rounding down), and modify by the highest pilot Skills from the team.
- Combined Mecha can use the FATE/Synergy points of any of the pilots to power its moves and special abilities.

Characters
FATE often uses a group or team-oriented character creation method. I’m not usually much of a fan of this approach, but for a Sentai game it makes a lot of sense. There should be some sort of commonality between the team’s members, both in terms of their overt purpose as super-sentai, and their cover story.
Sentai teams have been many things in the past. You might be able to draw some inspiration here for the theme of your team. This is just a handful of examples, including both their cover identities, and the themes of their outfits and abilities.
Athletes, Cards, Countries, Cyborgs, Dinosaurs, Elements, Fashion Models, Gemstones, High School Students, Inventors, Martial Arts Team, Ninjas, Olympians, Planets, Predators, Race Team, Rhythmic Gymnasts, Rock Band, Scientists, Secret Heritage, Siblings, Special Police Unit, Students.
It’s also a good idea to take this opportunity to define the source of the threat that they are coming together to fight. Some examples include:
Alien Invaders, Crime Syndicate, Demon Clan, Dimensional Invaders, Evil Magician, Evil Scientist, Evolved Dinosaurs, Ghosts, Hollow Earth Empire, Ninja Clan, Space Pirates, Spirits, Terrorists, Time Travellers, Vampires.
Example: Inu Burasage is the Black Ranger in Science Ninja Team Matsukaze. The team is made up of three Science Ninjas, who are also stuntmen – their cover identity. The Black Ranger is joined by the white and grey rangers, who combine their Mecha to form Robo-Matsukaze to take on larger threats. Together they battle alien infiltration and terrorism conducted by Tokage No Ō and the Lizard Men from primeval Venus.
Making Your Character
Creating your character proceeds as normal, though you should try and make sure your character fits, at least minimally, into the group theme.
- One Concept Aspect, one Trouble Aspect, three free Aspects.
- 20 skills. I prefer free-spend, with a limit of +4 for a starting character, but you could go 1×4, 2×3, 3×2, 4×1 if you prefer a more forcefully rounded persona.
- 3-5 Stunts. These typically provide special, permanent bonuses of +2, allow the automatic invocation of aspects, or the manifestation of new capabilities.
- Refresh is 5, minus the number of Stunts that you have.
- Characters typically have 2 Mental and Physical Stress boxes, and three Consequences in each category. Sentai tends to be combat heavy, and while it’s not shy of killing off characters I’d still suggest upping the base Stress to 3. Additional Stress boxes (and Consequences) can come from Skills and can come from Stunts.

You’ll also get your colourful, skin-tight Sentai suit and helmet, that counts as Armour +1 (Skintight) by default, and can be summoned from your ring/belt-buckle/watch. You also get a basic sidearm that’s Weapon +1 (Laser Accurate). Special Sentai weapons will have to be paid for with Stunts or gained during the game – you have to have room to grow.
You’ll also need to create your personal Mecha!
Individual Mecha
Your Mecha is just as important as your character. When you’re creating your Mecha you need to also consider how it fits in with the other characters and their Mecha. Sentai Mechs typically have a running theme, like a type of animal, or fit together as different aspects of the same thing.
- Scale: A personal Mecha is usually Scale 1 (Motorcycle), 2 (Car), 3 (Tank) and not bigger.
- Concept Aspect: Just like a character, but portraying the Mecha’s true essence.
- Trouble: A drawback that the Mecha has, such as ‘slow to turn’ or ‘weak underbelly’.
- Bonus Aspect: A free extra aspect for the Mecha.
- Stunt: Mecha start with a single Stunt.
- Skills: You have 20 points to buy Skills for the Mecha, but these can only be spent on Athletics, Fight, Notice, Physique and Shoot. You can, however, also spend from this pool to buy additional things from the list below.
- Bonus Items: Armour (1-4), Weapons (1-4, each weapon has a free aspect), Extra Stunt (3 points), Bonus Aspect (1 point per Aspect or weapon Aspect), Independent FATE Pool (3 points per point).
- Stress: Mecha only have Physical Stress, but besides the Skill bonus you also get to add the Scale as additional Stress boxes.
Combiner
Combiner Mecha have to have ‘Combine’ as a Stunt, if it’s a major theme of the campaign you might want to let the players have it for free.
Mecha combiners are typically comprised of five mecha (two arms, two legs and a body-head), but they can be less (Dai-X: legs/body/head) or more (Super Turbo Robo: Legs, arms, body, armour). Combination Mecha can consist of as few as two, or as many as sixteen Mecha. Player groups are best kept at 4-6 players, so you may either want to be flexible, or plan around that.
The combined Mecha generally has a Scale of one higher than the individual Mecha that came together to form it. When it is beaten, it dissolves into its individual Mecha, but they’re no more damaged than they were when the Mecha combined.
- Scale: Constituent Mecha scale +1
- Skills: Take the highest Skill level in each skill from each constituent Mecha and count that, once, for the combined Mech, modified by the Skill of the leader (typically the guy in the head).
- Aspects: Aspects equal to the average of the Mecha making it up, rounded down. Give it new Aspects.
- Weapons: Re-Spend half the constituent Mecha’s weapon investment as new weapons.
- Armour: Take the average of the constituent mecha and round down.
- Stunts: Total and halve the number of Stunts from the constituent Mecha, and choose new ones.
- The Combination Mecha can use FATE points from any of its pilots.
- The Combination Mecha has its own stress track.

I might work this up into a longer version with more details and examples for Autopsy, and if there’s sufficient interest, into a more full game for FATE like Daikaiju Die.
