Info about the Gorldtsuikah family according to the scans:
-The Gorldtsuikah family are a 4-sibling team
-The Gorldtsuikah family got hold of the Geardaringer by stealing the plans for it from the Tojitendo when the Tojitendo attacked Kaizokutopia(Pirate-topia)
- Zox is the oldest of the Gorldtsuikah family and loves singing, fights the Tojitendo to fulfill a "certain goal"
- Flint ripped off the Tojitendo's tech to create theirs while in Kikaitopia(Machine-topia), she is a tomboy and quick to anger
- Cuttaner and Rikki are twins and have been stuck in their current form ever since visiting SD-topia
- The reason Twokaiser resembles Gokai Red is because when they were in the Gokaiger world Flint thought they were cool after seeing them in action so she ripped off their suit design when creating the Twokaiser suit
- The Gorldtsuikah family's rule of thumb is plunder what you want
- Twokaiser Shinken Form is achieved by using the hero side of the Cuttanger Gear, and is based off of Super Shinken Red
- Shinken Form uses the Geardaringer as a sword and is dubbed "Cool Samurai"
- Twokaiser Ohran form is achieved by using the hero side of the Rikki Gear, and is based off of Kingranger
- Ohran form specializes in hand-to-hand combat and is dubbed "Hot-blooded Superpower"
- Crocodaioh is the ship of the Gorldtsuikah family
- When Crocodaioh is under Cuttaner's control it can transform into the Crossky-oh, and later combine with Cuttaner to become Twokaioh Cuttaner
- When Crocodaioh is under Rikki's control it can transform into the Crolling-oh, and later combine with Rikki to become Twokaioh Rikki
-The Battle Caesar Robo is summoned when Stacaesar uses his Stacaesar Gear's back side


So now that we got the proper spelling of their family name, it is clear the name is a portmanteau of GOLD, WORLD, and TSUIKA.
GOLD + WORLD + TSUIKA = GORLDTSUIKAH

It really encapsulates who Zox is; He's a gold ranger, traverses worlds, and is the tsuika senshi of the show. Flint I have a feeling will be a mix between Sena from Kiramager and Akiko from Kamen Rider W. As for Cuttaner and Rikki I wanna know how they became super-deformed in SD-topia.
