General Notes

The Lunar Underground's second rebuild of a Zeklov-Astraea design, the GCD-01B Pollux is the yin to the GCD-01A's yang. Instead of focusing on offense, Pollux fills a primarily defensive role on the battlefield. It carries no ranged weapons, though its double carbyne armor can withstand nearly any conventional ordnance, while its ion field is capable of disrupting most plasma attacks.

In case an enemy is foolish enough to get in close, Pollux carries a dual plasma lance rivaling any contemporary plasma hand weapon. To supplement its already impregnable defenses, the GCD-01B carries a tower shield reinforced with 200 carbyne layers and a built-in ion field projector.

Like the GCD-01A Castor, Pollux is operated by an integrated A.I. of the same name. The brother machine intelligences train together constantly to hone their combat skills and perfectly synchronize their tactics.

Perhaps the GCD-01B's most impressive feature is its ability to enfold the GCD-01A, thus forming the GCD-02 Heavy Armor Gemini.

Combat Frame XSeed - Brian Niemeier


  1. I already talked about how Brian is so generous with the BaMs.

    Today, it's ArtAnon's turn.

    All the CF illustrations and colorings he's done have been wonderful, and executed with skill.

    Whether I had very specific ideas of what I wanted things to look like, or only the most vague, he put things together how I wanted them. Sometimes this required substantial revision. Sometimes--especially with coloring--only minor ones. Even if he wasn't sure I'd like it, he did exactly as I asked. And it turned out that it was exactly what I wanted.

    So thank you, ArtAnon, for all your work in making my Build-a-Mechs, all the Build-a-Mechs, and all the CFs you've done look wonderful.

    1. And for the rest, I hold that the Systems Overterrestrial Coalition must be destroyed.

    2. DJ

      Is this another one of yours?
      Golly you're as prolific as Browning. Soon you'll make a cameo in the novels!

      The idea was two AI-driven pilotless CFs, one Offense, one Defense, that can Voltron together. So the combined is still to come.

      So we have Castor + Pollux = Gemini, and Gemini will be showing up shortly.

      As for showing up in the story, you should read CY2 Gaiden first. Yours for the low, low price of signing up for the newsletter!

    4. DJ

      Guess I'll have to re read CY 2 again:)


    5. If you still haven't found me, let me know!

  2. D.J., thank you for your kind words. You and the other Build-a-Mech designers gave me a run for my money this time, but in a great way! All of this Indiegogo's BAMs were innovative and exceptionally fun to work, and I am pleased that we were able to realize the images of your Combat Frames. Most of all, I am gratified that the work brings you value.

    1. Thanks to all of you for materially increasing the beauty in the world.

  3. Did I miss Castor? That's a cool design.

    BTW, the main characters in Gemini Warrior are named Castor and Pollux.

    1. Castor: https://www.brianniemeier.com/2019/10/combat-frame-data-gcd-01a-castor.html

      And I've been reading that book. Similar concept of two that are close enough that they can become one. You have the C+P bracelets. Brian has, at my request, the C+P AIs.

    2. So that's the genesis of this design :)

      Thanks, JD!

    3. The twins are at work in XSeed, too! Very nice.

      Thanks for reading!

    4. And then Will Smith took it for Gemini Man.

      Besides, the real source for all of these was the Wonder Twins, right?

    5. The Wonder Twins if their powers were useful despite being tethered together. A team of two that compliment each other despite being opposites and needing each other to survive is an interesting place for characters to be in.

      Glad to see it being done in mecha form.

  4. THIS is one of the reasons why it's so much fun working with Brian's projects: his readers.
