Monster Zero x SciFi Japan - Archive Only

So I think I pretty much have all the R1 Toho sci-fi stuff. Figured I'd start fleshing out the next biggest studio of Daiei, which there really aren't that many releases stateside. So basically I just want a complete collection of all the R1 releases of these studios' kaiju/tokusatsu/yokai releases. Here's what I have so far (or plan to get):

Toho Films
All R1 Godzilla Films
Rodan / War of the Gargantuas
The Mysterians
The H-Man / Battle in Outer Space / Mothra
Varan
Matango
Atragon
Dogora
Frankenstien vs. Baragon
King Kong Escapes
Latitude Zero
Space Amoeba
War In Space
Rebirth of Mothra / Rebirth of Mothra II

Daiei/Kadokawa Films
All R1 Gamera Films
Daimajin Trilogy (waiting for blu-ray release)
Yokai Monsters 1-3
The Great Yokai War (I need to get yet)

Is there anything else I'm missing? I'm specifically looking for stuff in the usual kaiju/tokusatsu genre. Feel free to mention other Non-Toho Non-Daiei Japanese kaiju films as well. I've seen a couple but not many.

That's a pretty good list...it feels complete more or less.

There are some non-Toho, non-Daei films like The Magic Serpent and The Last Dinosaur...both are two of my favorite toku related films of all time

Toei's is available from Media Blasters.

Negadon

Negadon is awesome.

Didn't that guy do another film after that, like a year or 2 ago?

TripMasterMunky Iron King was not that good imo, but you're right it did have something going for it due to the two leads. Red Baron is awesome! Definitely give it a watch before you write it off.
