Korea sure loves to use the Force suffex.

No seriously, you guys should listen to their version of the Gokaiger ending them:

Power Rangers has a little bit of the same problem :lol

Time force! Time force! Pow! Er! Ran! Gers!
Wiilllddd Force~ Power Rangers~!

How did the Korean dub of Gokaiger explain the pre-Zyurangers. From what I've been told, they stop dubbing the Power Rangers shows in Korean after Wild Force and choose to dub the Super Sentai shows in Korean with the Power Rangers name slap on to it. Going from American actors to Japanese actors and two totally different story lines must bee really strange.

I love how fandub-ish the Korean dubs are. The VAs are terribly picked and do a barely even average job and the openings and endings have terrible editing and are mostly the instrumentals with say, guitar melody (Magiranger) or the Japanese Karaoke (Gokaiger) xD

They sorta just went with it and "retconned"a few things to fit the current localization of Super Sentai from what I have heard. And Wild Force was at least a decade ago so the current ages 5~9 probably wont remember the PR version since they got the dubbed Gaoranger a.k.a Jungle Force. Plus, Koreans are already familiar with Super Sentai even before MMPR existed because they had straight-to-video dub releases of Sentai starting with Flashman (Which is why a lot of people in Korea who grew up with those vhs tapes tend to call Super Sentai "Flashman series" or just "Flashman").
And after Kamen Rider Ryuki got a Korean dub, they brought back Super Sentai to Korea starting with Abaranger dubbed in Korean a.k.a. Power Ranger Dino Thunder.

Also, Gokaiger's Korean dub had as much of the previous dub cast from Abaranger to Goseiger back, and even got some applause when they brought back veteran voice actors who are well-known by their fans for having prominent roles in those dubbed VHS tapes. For example, the voice actor who voiced both Changegryphon and Yellowlion came back(He is most-known as the Korean voice of Jin/Redflash and Takeru/Redmask), and they even brought back the voice actor who has done many villain roles in those dubs as Ackdos Gil (He voiced Kiros from Maskman, Bio Hunter Silva from Bioman, and Dr. Kemp from Liveman to name a few.)

Some of the Localization threw me off when I heard them to be honest, but I heard the casting was considered either decent or pretty nice as far as Korean Toku dubs go. Plus, they got the Korean voice of Roronoa Zoro as Gokaired/Marvelous. How fitting.
For the curious few, here are the localized names of all the sentai as of Gokaiger/Captain Force(fyi "Super Sentai" or "Sentai" are localized as Power Ranger so I excluded them.)

And they say PR uses Force in the name too much >_>

That announcer is trying waaaaaay too hard. :lol

He will be Dr.Ulshade.
Also, upon some research, I found out he did the Korean voice for Bulk from MMPR(and amusingly, Jason was voiced by the Korean voice actor who voiced Redflash, Redmask, Yellowlion, and Changegryphon for the dubs).

*extra trivia: He is the Korean voice for most Samuel L. Jackson roles and notably voiced Zeus while Goseiknight's Korean VA voiced John McClane in Die Hard III.
