I was watching the 1993 cartoon "Adventures of Sonic the Hedgehog". There was a scene with Robotnik holding an evil robot convention. About two minutes in, I caught this:



The gold robot looks like one of the Robot Bombs, the red one looks a bit like manga Atlas, and the lavender-hooded guy behind them I've seen before, but I can't remember where.

Suddenly, the Hyotantsugi lookalike randomly slides in behind Robotnik and stays for a few seconds. Then, everybody sees Sonic, a fight ensues, and the four are gone.
As soon as I saw this, I had to take the pictures and bring them here. If you want to see the episode it's here, but in Swedish. It's the only high-quality copy I could find.
