The Mad Hatters

Gonbesu, Popy, Japan,
1970's

These 2 bots are just soo unique because they have hats. The first one is Gonbesu... a Japanese attempt of what a Mexican-sombrero type of robot should be.

Hao Taitei Ryu Knight DX Ryu Knight Bourus, Bandai, Japan,
1994

The second one, frankly, I don't know - some kind of priest head-gear? Found in London's Chinatown in the 1990's - looks to be a pre-Gundam show of some kind.
