Which footage crossed where — one row at a time.

The base of MMPR S1: Zyuranger combat/mecha footage with US-shot, unmorphed teen drama stitched on top.

Fresh: Unmorphed drama and the teen cast shot fresh in the US

Soga's Bandora footage was reused directly as Rita — the only actor who physically bridges both versions on screen. Rita's English voice was Barbara Goodson (not Soga); from mid-S2 the on-screen Rita was recast to Carla Perez. In the 1995 Japanese dub of MMPR, Soga re-voiced Rita herself.

A villain lieutenant who also appears in the newly-commissioned Zyu1.5 footage.

"Zyu1.5" — extra high-quality villain footage shot in Japan, made to lip-sync cleanly to the English dialogue. Machiko Soga (Bandora) and Ami Kawai (Lamie/Scorpina) were re-cast and performed anew to match the mouth movements of the English lines (e.g. "Magic Wand, make my monster grow!").

Carried over as the Megazord in both footage and toys — the prototype Megazord and a Bandai best-seller. The Japanese combination debuts in Ep.6.

The Green Ranger's personal Zord; the Japanese original debuts in Ep.21 (summoned by Burai with the Zyusouken). Dragon Ranger / Green Ranger (Tommy)'s machine.

The first time a sentai "sixth ranger" carried over as the US extra hero (the Japanese original debuts in Ep.17) — and in the US he became a breakout icon.

Introduced as the carrier Zord; the Japanese original debuts in Ep.29.

These suits became the toy brand, so they were kept through S2 and S3 rather than swapped for later shows' suits — the root cause of every later seam.

After Zyuranger footage ran out, Saban commissioned Toei and suit-maker Rainbow Productions to shoot new battles in Japan, never aired there, padding MMPR S1 to 60 episodes. "25" here counts the monsters actually used on screen (~15 in S1 plus ~10 in early S2), which is a different tally from the total number of Dora monster suits Toei built (sources vary). Whether each monster has a Ranger-sized fight, a Zord-sized fight or only isolated cuts varies by monster. Per Toei's Takeyuki Suzuki, the extra Japan shoots were inefficient, so later battles were shot in the US instead. The term "Zyu2" was coined by fan Chris Funaro, not an official label. Per-monster index below.

Fresh: Aired combined with US-shot unmorphed drama

The Dinozord-to-Thunderzord generation change. With Green already present and Black vacant, they were renamed/recolored (e.g. Black Lion).

The unmorphed cockpit shots were filmed fresh in the US.

Fresh: Thunder Megazord cockpit interiors

The sole Dairanger suit fully adapted — Tommy, having lost Green, returns as the White Ranger. KibaRanger (Kou) appears only intermittently in Dairanger from Ep.17 on (17–22, 28–31, 33–35, 37, 38, 42–finale), so the US filled the gap with fresh drama and the voice of the talking sword, Saba.

Some of the Tigerzord's warrior-mode footage was shot fresh in the US.

In Japan, Kiba Daioh is Won Tiger combined with Tenkuu Kiden (the carrier mecha). Since the US used neither the Dairanger suits nor the cockpit, the unmasked combination shots could not be reused and none were filmed fresh (a missing-cockpit case).

Monster footage was reused, but because the Dairanger hero suits were unused, edits keep monsters and Rangers from touching directly ("No Direct Contact"; ground fights were shot separately in the US with Z-Putties). Five Gorma monsters went unadapted: Pot Taoist (Tsubo Dōjin — its episode was scrapped after the movie reshoots; it would have been adapted as "Party Crasher"), Duke of Trump (the lead Gorma of the Dairanger movie), Boss Kamikaze, Teacher Telephone, and Bird Cage Vagrant.

Because the Zyuranger suits were the established toy brand, and Dairanger had no Black but a Green (clashing with the existing Dragon Ranger), the five suits were never adapted — "left on the cutting room floor." The single biggest decision behind the seam.

The neutral, judging dragon — left unused in the US version.

TV Asahi producer Atsushi Kaji testified that "to increase footage reusable in the overseas adaptation (MMPR), we reduced the unmasked (pre-transformation) drama of the regulars in the latter half of Kakuranger and made the show more orthodox overall" (Super Sentai Official Mook 20th Century, 1996 Carranger vol.). A rare explicit statement that the Japanese side made the show with reuse in mind. It does not contradict Takeyuki Suzuki's testimony (see the Zyu2 entry) — different show, different layer.

The five beasts that form Muteki Shogun (Red Saruder/ape, Blue Logan/wolf, Yellow Kumard/bear, Black Gamma/frog, White Kark/crane) became the Shogun Megazord in the US. The DX Muteki Shogun toy was re-released in North America as the DX Shogun Megazord: Red Saruder's kanji became a lightning bolt, Blue/Yellow were recoloured to Billy's and Aisha's suits, and White (Lark) was turned Pink for Kimberly/Katherine.

The upgrade to Muteki Shogun: five God-beasts (God Saruder and four others, from Ep.31 in Japan) combine into it, and in the US it became the Ninja Megazord. Kakure Daishogun + Tsubasamaru (Super Kakure Daishogun) maps to the US Ninja MegaFalcon Zord. A neat seam: Japan's order is Muteki Shogun then Kakure Daishogun, but the US order is reversed — Ninja Megazord (Kakure Daishogun) first, Shogun Megazord (Muteki Shogun) later. MMPR's Ninja Megazord battles were rendered in CGI, using the Kakuranger toys as design reference.

Lighter versions of the Shogunzords. In Japan the Beast General Fighters are piloted from inside; in the US, the Battle Borgs are summoned from the Alien Coins and controlled telepathically (a mental link) from off the battlefield (no combination or transformation) — a redesign that conveniently removes the need for cockpit/unmasked shots, easing reuse.

Yokai monsters reused but reordered, mixed with US-made Finster monsters and Tenga ground fights. About ten yokai whose Japanese motifs were too overt went unadapted — Bakeneko, Oonyuudou, the Hitotsume Kozou brothers, Dorotabo, Sunakake Babaa, Kamaitachi, Karakasa, Yuki-onna and others. A few suits (e.g. for Smudgey Swirl) were used only as background filler, with no fight footage.

The replacement for the Putties — MMPR's first foot soldiers that talk.

Not used as heroes in S3 proper, but adapted in the spin-off "Alien Rangers." The Japanese "earthly ninja" premise was dropped entirely and recast as water-dwelling aliens (the Aquitians) from the planet Aquitar. They also morph without a device, unlike Kakuranger's Doron Changer. All unmorphed drama was freshly shot with US actors.

A single episode that stitches together five sources — Zyuranger, Zyu2, Dairanger, Kakuranger and fresh US footage — the densest seam of all.
