History Tropers / Kuruni

*** '''Accel Booster''': Using Gaia Memory Enhancing Adapter to power-up the Accel Memory, most of Accel Booster's stats is between the default form and Accel Trial. This form has jet boosters all over his body and make him incredible agile in air and easily make up for lower strength with boosters' acceleration.
(Accel) and FragileSpeedster (Trial Mode). A DVD adds a LightningBruiser (Booster Mode).

%%** In ''Series/KamenRiderGaim'', the characters can exchange gear with one another to access several different "Arms" forms, but to keep things simple, we'll only list the Riders with multiple forms and only the Arms they have access to by default.

** Double: A little more complicated due to being a FusionDance with mix-and-match ComboPlatterPowers of Shotaro's "body" Gaia Memory and Philip's "soul" Gaia Memory, with each side providing half the form's stat balance.

*** '''Accel''': The default form. A downplayed version of MightyGlacier with high strength and while he isn't as nimble as his other forms, he is in no way sluggish and can changed into bike form for speed.
*** '''Accel Trial''': Gain SuperSpeed by [[ShedArmorGainSpeed Remove much of the armor of the default form]][[note]]Fast enough to dodge lightning[[/note]]. Although his strength is much lower than the default form, this can be make up by his [[DeathOfAThousandCuts rapid-overwhelming attacks]]. Naturally, [[FragileSpeedster his defense is low]].
*** '''Accel Booster''': Using Gaia Memory Enhancing Adapter to power-up the Accel Memory, most of Accel Booster's stats is between the default form and Accel Trial. However, this form has jet boosters all over his body and make him incredible agile in air and easily make up for lower strength with boosters' acceleration.

%%** [[Series/KamenRiderOOO OOO]]: Takes Double's ComboPlatterPowers UpToEleven and therefore '''WAY''' too varied to list all the possibilities. The notable ones are the matching sets: JackOfAllStats ([=GataKiriBa=] Combo), FragileSpeedster ([=LaToraTah=]), MightyGlacier ([=SaGoZo=]), LightningBruiser ([=TaJaDor=]), SquishyWizard ([=ShaUTa=]), and SuperMode ([[DeadlyUpgrade PuToTyra]]); everything else including the default [=TaToBa=] Combo is a MasterOfNone. OOO is the first Rider to get multiple one-time movie forms: a StoneWall ([=BuraKaWani=]) and two alternate {{Super Mode}}s ([[FightingClown TaMaShii]] and [[UpToEleven Super TaToBa]]).

This trope is a tradition for Heisei-era series.
* ''Series/KamenRiderBlackRX'': Black RX has three forms.
** '''Black RX''': The default [[JackOfAllStats balance form]].
** '''Robo Rider''': The MightyGlacier with [[SuperToughness high defense]] and armed with a powerful [[{{Handgun}} Vortech Shooter]], but his robotic movement is sluggish.
** '''Bio Rider''': A combination of FragileSpeedster and StoneWall, with nimble movement and ability to transformed into gel which make him almost invincible. But his Bio Blade is weak, the armor is thin, and it's hinted that he's weak against heat while in gel state[[note]]During a fight against [[ArchEnemy Shadown Moon]] he uses the gel transformation to escape from Shadow Moon's grab, then Shadow Moon uses Shadow Beam to heat up the ground around him instead of attacking him directly. It forces him to switch back to humanoid form, clearly injured[[/note]].
* ''Series/KamenRiderKuuga'':
** Kuuga has four basic forms.
*** '''Mighty''': The [[JackOfAllStats balance form]].
*** '''Dragon''': [[FragileSpeedster Fast and can jump very high but has the least protective armor]], and is so weak that he needs a [[SimpleStaff Dragon Staff]] to injure an enemy.
*** '''Pegasus''': Has SuperSenses capable of perceiving ultraviolet light and ultrasonic sound, but even with focus training Kuuga can only use this form for 2 minutes before suffering from SensoryOverload. It's armed with a Pegasus Bowgun which [[GlassCannon shoots out a powerful air blast but has to be reloaded after every shot]].
*** '''Titan''': MightyGlacier, with high strength to wield the [[CoolSword Titan Sword]] and strong protection from ArmorOfInvincibility, but the sword and armor are so heavy that it's the slowest form. Despite its high defense, the armor still leave some area exposed so the enemy can exploit AttackItsWeakPoint.
*** All of the basic forms later get a MidSeasonUpgrade as '''Rising''' form that boost their stats[[note]]Rising Mighty just gets an overall stats boost, Rising Dragon has increased speed and the Rising Dragon Rod now has [[BladeOnAStick blades on both ends]], Rising Pegasus has better SuperSenses and the Rising Pegasus Bowgun can shoot repeatedly, and Rising Titan has increased strength and bigger swords that he can [[DualWielding use two at once]][[/note]] but they're more of LimitBreak that only lasts for 30 seconds, and the power can [[DestructiveSavior cause serious collateral damage to civilians]].
** He also has three unusual forms:
*** '''Growing''': The weakest, only used when he doesn't get access to other forms[[note]]The first time because he lacks the resolve of a warrior and later when he's still weakened from a near-death state, we also see him revert to this form briefly after his SensoryOverload from Pegasus Form[[/note]]. Usually regarded as useless but proven to be [[NerfArm capable of fighting, just not being good at it]].
*** '''Amazing Mighty''': LightningBruiser, with an overall stats boost from Rising Mighty Form.
*** '''Ultimate''': [[EleventhHourSuperpower Used in the last battle]], [[SuperMode superior to everything before it in every respect]] but it's a SuperpoweredEvilSide and can corrupt him into an evil being.
* ''Series/KamenRiderAgito'': Agito has three basic forms and three super forms.
** '''Ground''': Has the lowest defense but high attack power.
** '''Storm''': Faster and has better armor than the Ground form, but has a weaker attack.
** '''Fire''': Has SuperSenses and the best defense among basic forms, but is also slower. Has higher attack power than Storm Form but lower than Ground Form.
** '''Trinity''': The LightningBruiser that [[AllYourPowersCombined combines the advantages of the basic forms]].
** '''Burning''': [[MightyGlacier Stronger and has better defense than Trinity Form but is much slower]].
** '''Shining''': SuperMode. Is as strong as Burning Form but is also the fastest. The downside is that he usually has to activate this form by exposing the Burning Form to sunlight to ShedArmorGainSpeed.
* ''Series/KamenRiderKabuto'':
** Most of the Riders have two forms:
*** '''Masked''': Technically a MightyGlacier with heavy armor and high strength, but is slow. However, since Worms can move with SuperSpeed, in practice Masked Form is useless against anything stronger than {{mooks}}.
*** '''Rider''': Technically a FragileSpeedster, made by [[ShedArmorGainSpeed removing much of the armor of the Masked Form]] and adding SuperSpeed capability. As noted, since SuperSpeed is needed to fight Worms effectively, this is their main form in practice.
*** Gatack emphasizes the strength of both forms with his weapons. In Masked Form he has a pair of {{Shoulder Cannon}}s that can tear through group of mooks with ease but has no chance to hit anything with SuperSpeed, so his Rider Form is instead armed with [[DualWielding a pair of swords]].
** Kabuto (as does Gatack in a DVD) also gets a '''[[SuperMode Hyper Form]]''' that is more powerful and even faster than Rider Form, but it requires MidSeasonUpgrade [[TransformationTrinket Hyper Zecter]] to activate.
* ''Series/KamenRiderDenO'':
** Den-O:
*** '''Plat''': The base form of the Aura Armor. Almost useless in a fight ([[JokeCharacter doesn't stop Ryotaro from trying and get his ass kicked though]]).
*** '''Sword''': Possessed by Momotaros. This is the [[JackOfAllStats balance form]].
*** '''Rod''': Possessed by Urataros. Has [[StoneWall high defense but low offense]]. This form is [[OlympicSwimmer good for aquatic combat]] and the [=DenGasher=] rod mode has [[YouWillNotEvadeMe the power of capturing an escaping enemy]].
*** '''Ax''': Possessed by Kintaros. [[MightyGlacier Slow but strong]], and has [[SuperToughness the best defense]].
*** '''Gun''': Possessed by Ryutaros. [[LightningBruiser Faster than Sword Form and armed with a powerful DenGahser gun mode]]. Ryutaros also incorporates break dancing into his fighting style, making it [[ConfusionFu hard to predict]]. However, Ryutaros's trigger-happy carelessness tends to cause serious collateral damage.
*** '''Wing''': Possessed by Sieg. [[LightningBruiser Even faster than Gun Form]] and armed with [[DualWielding a combination of a boomerang and a handaxe]]. But Sieg is the SixthRanger of the group, often not available, and [[TheFriendNobodyLikes the team loathe him]]. His arrogant attitude also makes him prone to make mistakes in battle[[note]]For example, he usually puts his hands behind his waist during a fight[[/note]].
*** '''Climax''': [[AllYourPowersCombined Combines powers of the four Taros into one form]]. This form require a [[TransformationTrinket Climax Cellphone K-Taros]], and all four Taros need to work together controlling a single body.
*** '''Super Climax''': [[UpToEleven Even more powerful than Climax Form]], at the cost of fusing with [[TheFriendNobodyLikes Sieg]].
*** '''Liner''': Using [[CoolSword DenKamen Sword]], Ryotaro can transform into this form without being possessed by Imagin. It's the fastest form and relatively stronger than most, except Climax Form. The downside is Ryotaro's low combat skill, which is remedied to a degree as he can select one of the Taros to advice him through the [=DenKamen Sword=], allowing him to [[DittoFighter utilize their fighting style depend of the situation]].
** [[TheLancer Zeronos]]:
*** '''Altair''': His default [[JackOfAllStats balance form]]. Also, Deneb is independent from Zeronos in this form and can assist him otherwise.
*** '''Vega''': Fused with Deneb. Becomes [[MightyGlacier slower but stronger]] as well as gaining [[SuperToughness improved defense]] and being equipped with a powerful set of {{Shoulder Cannon}}s.
*** '''Zero''': Transformed by using the Red Zeronos card. [[LightningBruiser Marginally weaker than Vaga Form but much faster than Altair Form]] and equipped with a powerful Denebick Buster gun (which can qualify as both {{BFG}} and GatlingGood).
* ''Series/KamenRiderKiva''
** Kiva:
*** '''Kiva''': The default form with [[JackOfAllStats balance stats]] and high jump power that makes him good with an acrobatic aerial fighting style.
*** '''Garulu''': Transformed by using [[CoolSword Garuly Saber]]. Has the fastest land speed and a stronger kick in exchange for lower arm strength.
*** '''Basshaa''': Transformed by using [[{{Handgun}} Basshaa Magum]] and has [[SuperSenses sharp vision]] to make better use of it. Marginally faster than Kiva Form but weaker in everything else. However, this form is [[OlympicSwimmer good for aquatic combat]] and capable of creating water even on dry land.
*** '''Dogga''': Transformed by using [[DropTheHammer Dogga Hammer]]. He gains SuperStrength to wield it and heavy armor. [[MightyGlacier Naturally, this costs him speed]].
*** '''[=DoGaBaKi=]''': Transformed by [[AllYourPowersCombined using all three Arms Monsters at once]] and can use all three weapons at once. Has higher kick power than basic forms, but weaker arm strength than Dogga, slower than Garulu, and lower jump than Kiva. This form also causes high physical stress, so it can only safely activate for 5 minutes.
*** '''Emperor''': SuperMode activated by having Tatsulot remove his PowerLimiter. Superior to the basic forms in almost every respect[[note]]the sole exception is speed, which is slower than Garulu[[/note]] and can use the Arms Monster without transforming as well as the new [[CoolSword Zanvat Sword]].
*** '''[=DoGaBaKi=] Emperor''': Only seen in a DVD. Activated by transforming into Emperor Form while in [=DoGaBaKi=] Form. Supposedly it's [=DoGaBaKi=] Form [[PaletteSwap with Emperor Form's combat abilities]].
*** '''Emperor Bat'''[[note]]also known as Flight Style[[/note]]: [[PowerUpgradingDeformation Transform from Emperor Form]] into a [[BatOutOfHell bat monster]]. [[{{Flight}} Can fly]] at a speed over mach 3.4 and is powerful enough to engage in a fight against a [[{{Kaiju}} Sabbat]].
** On surface, [[TheRival Ixa]] seems to use NextTierPowerUp with each form (Save Mode > Burst Mode > Risingng Ixa) being stronger than before. However, the Save Mode has its use as fail-safe to the Burst Mode by lowering the PoweredArmor's output and disabling some functions to stabilize the system. It's just that after 22 years of development, Ver.X armor's Burst Mode is reliable enough.
* ''Series/KamenRiderDecade'':
** Decade's loaded thanks to PowerCopying other riders, primarily the nine preceding him, and most of ''their'' forms (he doesn't get their upgraded LightningBruiser or SuperMode forms, with one exception, nor that he gets their JokeCharacter forms either). As the stats and abilities of Riders differ from series to series, here're some notable ones:
*** [[Series/KamenRider555 Faiz Accel form]] functions as a substitute for Kabuto's SuperSpeed.
*** Den-O's four basic forms are {{Joke Character}}s at first. All they do is strike a pose and say their CatchPhrase.
** Decade also has two {{Super Mode}}s:
*** '''Complete''': In addition to the usual stats boost, it also has the ability to summon previous Riders' SuperMode to assist him in attacking.
*** '''Violent Emotion''': SuperpoweredEvilSide that's used when Decade fulfills his role as the destroyer of worlds. It allows him to use the powers and tools of other riders without changing to other forms.
** Yusuke Onodera's Kuuga can switch forms just like the original series except for the Rising forms and Amazing Mighty Form. However, he can take Ultimate form UpToEleven with the even more powerful '''Rising Ultimate Form'''.

*** '''[=FangJoker=]''': Combination of Philip's Fang Memory and Shotaro's Joker Memory and [[LightningBruiser stronger than the normal combinations]]. However this form use Philip's body instead of Shotaro's and his weak physical body mean it can't be used for long periods of time and he might [[The Berserker lose control of himself when in this form]].
*** '''[=CycloneJokerXtreme=]''':
** Past the regular combos, you've got a LightningBruiser ([=FangJoker=]) and a SuperMode ([=CycloneJokerXtreme=]). The movies take this last one UpToEleven ([[GoldenSuperMode CycloneJokerGoldXtreme]]) and near the end of the series the ability to have just one person use a single power as a MasterOfNone is added (usually Shotaro with Joker, occasionally Philip with Cyclone).

** '''Ground''': Has lowest defense but high attack power.
** '''Storm''': Faster and has better armor than Ground form, but has weaker attack.
** '''Fire''': Has SuperSenses and the best defense among basic forms but is also slower. Has higher attack power than Storm Form but lower than Ground Form.
** '''Trinity''': The LightningBruiser that [[AllYourPowersCombined combine the advantages of the basic forms]].

** '''Shining''': SuperMode. Being as strong as Burning form but is also the fastest. The downside is that he usually has to activate this form by expose the Burning Form to sunlight to ShedArmorGainSpeed.

*** '''Masked''': Technically a MightyGlacier with heavy armor and high strength, but is slow. However since Worms can move with SuperSpeed, in practice Masked Form is useless against anything stronger than {{mooks}}.
*** '''Rider''': Technically a FragileSpeedster by [[ShedArmorGainSpeed remove much of the armor of the Masked Form]] and has SuperSpeed capability. As noted, since SuperSpeed is needed to fight Worms effectively this is their main form in practice.
*** Gatack emphasize the strength of both forms with his weapons. In Masked Form he has a pair of ShoulderCannon that can tear through group of mooks with ease but has no chance to hit anything with SuperSpeed, so his Rider Form is instead armed with [[DualWielding a pair of sword]].
** Kabuto (as does Gatack in a DVD) also gets a '''[[SuperMode Hyper Form]]''' that is more powerful and even faster than Rider Form, but it require MidSeasonUpgrade [[TransformationTrinket Hyper Zecter]] to activate.

*** '''Rod''': Possessed by Urataros. Has [[StoneWall high defense but low offense]]. This form is [[OlympicSwimmer good for aquatic combat]] and the [=DenGasher=] rod mode has [[YouWillNotEvadeMe power to capture an escaping enemy]].

*** '''Gun''': Possessed by Ryutaros. [[LightningBruiser Faster than Sword Form and armed with a powerful DenGahser gun mode]]. Ryutaros' also incorporates break dancing into his fighting style, make it [[ConfusionFu hard to predict]]. However, Ryutaros's trigger-happy carelessness trend to cause serious collateral damage.
*** '''Wing''': Possessed by Sieg. [[LightningBruiser Even faster than Gun Form]] and armed with [[DualWielding a combination of a boomerang and a handaxe]].

*** '''Ultimate''': [[EleventhHourSuperpower Used in the last battle]], [[SuperMode superior to everything before it in every aspect]] but it's SuperpoweredEvilSide and can corrupt him into evil being.

** Double: A little more complicated due to being a FusionDance with mix-and-match ComboPlatterPowers of a "body" and a "soul" Gaia Memory, with each side providing half the form's stat balance.

*** Joker: Body's side. A [[JackOfAllStats balance unarmed fighter]].
, StoneWall (Metal), and GlassCannon (Trigger); and Philip's are FragileSpeedster (Cyclone), MightyGlacier (Heat), and SquishyWizard (Luna). So, using the most common combinations as examples, [=CycloneJoker=] is balanced with an edge toward speed, [=HeatMetal=] is especially slow but the major powerhouse, and [=LunaTrigger=] can't do melee but is great at trick shots. Past the regular combos, you've got a LightningBruiser ([=FangJoker=]) and a SuperMode ([=CycloneJokerXtreme=]). The movies take this last one UpToEleven ([[GoldenSuperMode CycloneJokerGoldXtreme]]) and near the end of the series the ability to have just one person use a single power as a MasterOfNone is added (usually Shotaro with Joker, occasionally Philip with Cyclone).

SuperMode (Emperor), and OneWingedAngel (Flight Style). A DVD pushes the SuperMode UpToEleven ([[AllYourPowersCombined DoGaBaKi Emperor]]).

*** Gatack emphasize the strength of both forms with his weapons. In Masked Form he has a pair of ShoulderCannon that can tear through numerous mooks with ease but has no chance to hit anything with SuperSpeed, so his Rider Form is instead armed with [[DualWielding a pair of sword]].

** Den-O: By itself, the Aura Armor is in '''[[PunnyName Plat Form]]''' which is almost useless in a fight ([[JokeCharacter doesn't stop Ryotaro from trying and get his ass kicked though]]). But it can transform into more powerful forms by have an Imagin possess Ryotaro.

*** '''Rod''': Possessed by Urataros. Has [[StoneWall higher defense but low offense]]. This form is [[OlympicSwimmer good for aquatic combat]] and the [=DenGasher=]'s rod mode has [[YouWillNotEvadeMe power to capture an escaping enemy]].

*** '''Gun''': Possessed by Ryutaros. [[LightningBruiser Faster than Sword Form and armed with a powerful gun]]. Ryutaros' also incorporates break dancing into his fighting style, make it [[ConfusionFu hard to predict]]. However, Ryutaros's trigger-happy carelessness trend to cause serious collateral damage.
*** '''Wing''': Possessed by Sieg. [[LightningBruiser Even faster than Gun Form]] and armed with [[DualWielding a combination of a boomerang and a handaxe]]. However, Sieg is SixthRanger of the group, often not available, and [[TheFriendNobodyLikes the team loathe him]]. His attitude also make him prone to make mistake in battle[[note]]For example, he usually places his hands behind waist during a fight[[/note]].

** Although [[TheLancer Zeronos]] has Plat Form as well, he never seen fighting in it.
*** '''Altair''': His default [[JackOfAllStats balance form]].
*** '''Vega''': Possessed by Deneb. Become [[MightyGlacier slower but stronger]] as well as [[SuperToughness improved defense]] and equipped with powerful set of ShoulderCannon.
*** '''Zero''': Transformed by using Red Zeronos card. Marginally weaker than Vaga Form [[LightningBruiser but faster than Altair Form and equipped with Deneb morph into powerful Denebick Buster gun (which can qualified as both {{BFG}} and GatlingGood).

*** Complete form: In addition to usual stats boost, it's also has ability to summon previous Riders' SuperMode to assist him in attack.
*** Violent Emotion: SuperpoweredEvilSide that's used when Decade fulfill his role as the destroyer of worlds. Allow him to use the power and tools of other riders without changing to other forms.
** Yusuke Onodera's Kuuga can switch form just like the original series except for the Rising forms and Amazing Mighty form. However, he can take Ultimate form UpToEleven with even more powerful Rising Ultimate form.

** ''Fire''': Has SuperSenses and the best defense among basic forms but is also the slowest. Has higher attack power than Storm form but lower than Ground form.

** '''Burning''': [[MightyGlacier Stronger and has better defense than Trinity form but is much slower]].

*** '''Titan'': MightyGlacier with high strength to wield [[CoolSword Titan Sword]] and strong protection from ArmorOfInvincibility, but the sword and armor is so heavy that it's the slowest form and despite its high defense, the armor still leave some area exposed so the enemy can exploit AttackItsWeakPoint.

*** '''Vega''':
*** '''Zero''':

*** '''Climax Form''': [[AllYourPowersCombined Combine powers of the four Taros into single form]]. This form require a MidSeasonUpgrade [[TransformationTrinket Climax Cellphone K-Taros]], and all four Taros need to work together controlling a single body.
*** '''Super Climax Form''': [[UpToEleven Even more powerful than Climax Form]], at cost of fusing with [[TheFriendNobodyLikes Sieg]].
*** '''Liner Form''': Using [[CoolSword DenKamen Sword]] Ryotaro can transform into this form without being possessed by Imagin. It's the fastest form and relatively stronger than most except Climax Form. The downside is Ryotaro's low combat skill, which is remedied to a degree as he can select one of the Taros to advice him through [=DenKamen Sword=], allow him to [[DittoFighter utilize their fighting style depend of the situation]].

** Black RX: The [[JackOfAllStats balance form]].
** Robo Rider: MightyGlacier with [[SuperToughness high defense]] and armed with powerful [[{{Handgun}} Vortech Shooter]], but his robotic movement is sluggish.
** Bio Rider: A combination of FragileSpeedster and StoneWall with nimble movement and ability to transformed into gel which make him almost invincible. But his Bio Blade is weak, the armor is thin, and it's hinted that he's weak against heat while in gel state[[note]]During a fight with [[ArchEnemy Shadown Moon]], he use the gel transformation to escape from Shadown Moon's grab and Shadow Moon uses his Shadow Beam to heat up the ground around him instead of directly attack him. It force him to switch back to humanoid form, clearly injured[[/note]].

*** Mighty: The [[JackOfAllStats balance form]].
*** Dragon: [[FragileSpeedster Fast and can jump very high but has the least protective armor]], and is so weak that he need a [[SimpleStaff Dragon Staff]] to injure enemy.
*** Pegasus: Has SuperSenses capable of perceiving ultraviolet light and supersonic sound, but even with focus training Kuuga can use this form for 2 minites before suffered from SensoryOverload, it's armed with Pegasus Bowgun which [[GlassCannon shoot out a powerful air pressure but has to reload after every shot]].
*** Titan: MightyGlacier with high strength to wield [[CoolSword Titan Sword]] and strong protection from ArmorOfInvincibility, but the sword and armor is so heavy that it's the slowest form and despite its high defense, the armor still leave some area exposed so the enemy can exploit AttackItsWeakPoint.
*** All of the basic forms later get MidSeasonUpgrade as Rising form that boost their stats[[note]]Rising Mighty just get overall stats boost, Rising Dragon has increased speed and the Rising Dragon Rod now has [[BladeOnAStick blades on both end]], Rising Pegasus has better SuperSenses and the Rising Pegasus Bowgun can shoot repeatly, and Rising Titan has increased strength and bigger sword than he can [[DualWielding use two at once]][[/note]] but they're more of LimitBreak that last only for 30 seconds, and the power can [[DestructiveSavior cause serious collateral damage to civilians]].

*** Growing: The weakest and only used when he doesn't get access to other forms[[note]]The first time because he lack the resolve of warrior and later when he's still weaken from near-death state, we also see him revert to this form briefly after has SensoryOverload from Pegasus Form[[/note]]. Usually regarded as [[JokeCharacter useless]] but proven to be [[NerfArm capable to fight, just not good at it]].
*** Amazing Mighty: LightningBruiser with overall stats boost from Rising Mighty Form.
*** Ultimate: [[SuperMode superior to everything before it in every aspect]], but it's SuperpoweredEvilSide and can corrupt him into evil being.

** Ground: GlassCannon with lowest defense but high attack power.
** Storm: Faster and has better armor than Ground form, but weaker attack.
** Fire: Has SuperSenses and the best defense among basic forms but is also the slowest. Has higher attack power than Storm form but lower than Ground form.
** Trinity: LightningBruiser that [[AllYourPowersCombined combine the advantages of the basic forms]].
** Burning: [[MightyGlacier Stronger and has better defense than Trinity form but is much slower]].
** Shining: SuperMode. Being as strong as Burning form but is also the fastest. The downside is that he usually has to activate this form by expose the Burning Form to sunlight to ShedArmorGainSpeed.

*** Masked: Technically MightyGlacier with heavy armor and high strength, but is also slower. However since Worms can move with SuperSpeed, in practice Masked Form is useless against anything stronger than {{mooks}}.
*** Rider: Technically FragileSpeedster by [[ShedArmorGainSpeed remove much of the armor of the Masked Form]] and has SuperSpeed capability. As noted, since SuperSpeed is needed to fight Worms effectively this is their main form in practice.

** Kabuto (as does Gatack in a DVD) also gets a [[SuperMode Hyper Form]] that is more powerful and even faster than Rider Form, but it require MidSeasonUpgrade [[TransformationTrinket Hyper Zecter]] to activate.

** Den-O: By itself, the Aura Armor is in [[PunnyName Plat Form]] which is almost useless in a fight ([[JokeCharacter doesn't stop Ryotaro from trying and get his ass kicked though]]). But it can transform into more powerful forms by have an Imagin possess Ryotaro.

Movies make it [[UpToEleven even more powerful]] Super Climax Form at cost of fusing with [[TheFriendNobodyLikes Sieg]].
** When the Taros fail to synchronize with Ryotaro, they create a [[CoolSword DenKamen Sword]] that allow him to transform into Liner Form. It's the fastest form and relatively stronger than most except Climax Form. The downside is Ryotaro's low combat skill, which is remedied to a degree as Ryotaro can select one of the Taros to advice him through [=DenKamen Sword=], allow him to [[DittoFighter utilize their fighting style depend of the situation]].

** Shining: SuperMode. Being as strong as Burning form but is also the fastest. The downside is that he usually has to activate this form by expose the Burning form to sunlight to ShedArmorGainSpeed.

*** Masked: Technically MightyGlacier with heavy armor and high strength, but is also slower. However since Worms can move with SuperSpeed, in practice Masked form is more of JokeCharacter that's useless against anything stronger than {{mooks}}.
*** Rider: Technically FragileSpeedster by [[ShedArmorGainSpeed remove much of the armor of the Masked form]] and has SuperSpeed capability. As noted in Masked form, since SuperSpeed is needed to fight Worms effectively this is their main form in practice.

** Black RX: JackOfAllStats with balance stats.

*** Mighty: JackOfAllStats with balance stats.

*** Growing: The weakest and only used when he doesn't get access to other forms[[note]]The first time because he lack the resolve of warrior and later when he's still weaken from near-death state, we also see him revert to this form briefly after has SensoryOverload from Pegasus form[[/note]].

** Double: A little more complicated due to being a FusionDance with mix-and-match ComboPlatterPowers, with each side providing half the form's stat balance: Shotaro's powers are JackOfAllStats (Joker), StoneWall (Metal), and GlassCannon (Trigger); and Philip's are FragileSpeedster (Cyclone), MightyGlacier (Heat), and SquishyWizard (Luna). So, using the most common combinations as examples, [=CycloneJoker=] is balanced with an edge toward speed, [=HeatMetal=] is especially slow but the major powerhouse, and [=LunaTrigger=] can't do melee but is great at trick shots. Past the regular combos, you've got a LightningBruiser ([=FangJoker=]) and a SuperMode ([=CycloneJokerXtreme=]). The movies take this last one UpToEleven ([[GoldenSuperMode CycloneJokerGoldXtreme]]) and near the end of the series the ability to have just one person use a single power as a MasterOfNone is added (usually Shotaro with Joker, occasionally Philip with Cyclone).

** Gatack emphasize the strength of both forms with his weapons. In Masked form he has a pair of ShoulderCannon that can tear through numerous mooks at once but has no chance to hit anything with SuperSpeed, so his Rider form is instead armed with [[DualWielding a pair of sword]].
