A recent subject of my fascination is an old robot that I previously had no interest in, but after learning more, it grew on me. It's the Walker Gallia (sometimes spelled as Galliar) from the 1982 series Blue Gale Xabungle. It's the second mecha that the protagonist Jiron Amos uses in the series.
This robot may look ugly to some, but I like its brutish bulk. The head in reminiscent of the Zaku I from the Gundam series. Its looks are also more cartoonic than in other series, but I accept is as part of the series design. I hope to get the Real Robot Revolution version of this if I have money.
