[[WMG: Masked Rider is a prequel to KamenRiderDragonKnight.]]
Dex is the original Advent Master.

[[WMG: Dex is an InvoluntaryShapeshifter.]]
This is why sometimes he resembles [[Series/KamenRiderBlackRX Kotaro Minami]].

[[WMG: The Masked Rider armour changes form sometimes to protect itself.]]
This is why it sometimes resembles that which was worn by ''Film/KamenRiderZO'' and ''Film/KamenRiderJ''.

[[WMG: Dregon left Earth to conquer another world by the time of ''Series/PowerRangersZeo''.]]
In the episode of ''Zeo'' where the Red Battlezord is introduced, Zordon says something along the lines that it is the last line of defence on Earth (now that the Zeo Megazord is out of action), implying that Dex has left Earth to fight Dregon elsewhere.

Mondo probably attacked his ship as well upon the Machine Empire's arrival to Earth, forcing Dregon to retreat in disgrace (much to Zedd's amusement upon hearing this) as Dex and Ferbus chased after him, knowing the Rangers would be capable of dealing with the Machine Empire themselves.

This also explains his absence during [[Series/PowerRangersInSpace Countdown To Destruction]]; he was fighting Dregon's forces elsewhere.

[[WMG: The version of events we saw was a ShowWithinAShow in the Franchise/PowerRangers Universe]]
This is how Nadira got to watch the show in ''Series/PowerRangersTimeForce''. After defeating Dregon, Dex sold his story to some tv execs.

This also explains the differences of Dex's departure between "A Friend In Need part 3" and "Escape From Edenoi part 1". In the former episode, his grandfather tells him that there is no hope left for Edenoi, implying the planet is about to explode or something. Then in the latter episode, Dex is told by his grandfather to leave Edenoi again, without any sign the planet is going to go bust. It also explains why Doubleface acts as Dregon's second in command in the former, but not in the latter, how was Dex to know the chain of command inside Dregon's ship?

[[WMG: Doubleface got a demotion after "A Friend In Need part 3"]]
This is why he behaves as Dregon's second in command in that episode and why afterward he has the same role as the others.

[[WMG: The Masked Rider will return for ''Series/PowerRangersSamurai''.]]
It's been confirmed that ''Series/SamuraiSentaiShinkenger'' is getting adapted for ''Series/PowerRangersSamurai''. ''Shinkenger'' featured a crossover with ''Series/KamenRiderDecade''. Hopefully, if the writers will be mythos-savy enough to recall the ''Power Rangers / Masked Rider'' crossover and take advantage of this footage to have Dex appear in the new series, either as a reboot or a continuation from his arc. And they'll do it ''right'' this time. Please?
* Problem is, Decade's suit looks even less like Black RX's than ZO and J's did. If they use the Decade footage, it would make more sense for the Riders to be new characters. What they ''should'' do is adapt Double and then let the Goseiger adaptation cross over with ''that.'' A lot.
** HOWEVER! They may handwave it with that the Decade suit was made to replace the original Masked Rider suit because the original wasn't enough to fight the evil on Earth at the time or something.
*** They could also state that since we've last seen him, Dex has defeated Count Dregon, his father has passed away, and he's now the king of Edenoi, and that the Decade suit is his royal suit of armour. After all, purple is a colour of royalty, and magenta is close enough...
*** Remember that the past Riders were previous users of the same powers, pulled through time? Decade can be Dex's son, with the suit having changed to adapt to him.

[[WMG: Dex died on his way to Earth after a Freind in Need Part 3]]
Considering Masked Rider is likely not part of the official Power Rangers universe, and Dex was never heard from again. Instead of fighting Dregon on Earth, he sacrificed himself to destroy him.

[[WMG: The show is something {{Pilot}} Dex or his family cooked up to cover up fighting real monsters]]
I mean it's not like [[Series/PowerRangersNinjaStorm Power Rangers]] are real or anything

[[WMG: The green suit Masked Rider keeps shifting into in the first episodes was his form "molting" to his default form]]

[[WMG: Albee being black despite being in a White/Asian family is a reference to the [[Series/KamenRiderBlackRX source material]].]]
The ''Series/KamenRiderBlack'' transformation was originally known as "Black Sun". [[FridgeBrilliance Albee is the Stewart family's]] [[IncrediblyLamePun black son]].
* [[WesternAnimation/FamilyGuy Except Albee's not a ninja...]]

[[WMG: The series DID get a proper resolution. Only it happened off-screen...]]

...during the events of Countdown to Destruction. Zordon's Energy wave also destroyed Dregon and his forces.
* More likely it purified Dregon to good like Rita, Zedd, Divatox, and Astronema (all human-looking villains like Dregon) while destroying the rest of his forces. Afterwards, Dregon [[HeartwarmingMoment reconciled with his father Lexion and nephew Dex]].

[[WMG: The World of Masked Rider is an [[Series/KamenRiderDecade A.R. World]].]]

[[WMG: Dex's grandfather, King Lexian, was Z-Cross for his Masked Rider tenure.]]
It was likely the most recent previous incarnation of the Rider armor, and the title is passed down, so it would make sense.

[[WMG: The first two Riders were twins.]]
While we're on the subject of that armor changing for each user. The first two are nigh-identical. By ''Masked Rider'' rules, that would mean the wearers had to be nigh identical as well, right? Moreso than most relatives, as no other two look alike. (And, as mentioned before, ''one'' of the Riders, most likely ZX, was a younger Lexian!)

[[WMG: ...And Rider-1 met an untimely end.]]
However, there is only ''one'' set of Rider powers, passed down, which means Rider-1 and Rider-2 can't have been active at the same time.
