Quick! Say the names of the characters you see in this picture!
Did you say Bocoe & Decoe from Sonic X? If you did, you would be... somewhat wrong because this is a surprise reverse...cameo? The robots you are looking at here are actually Omega & Epsilon from TMS Hasshin. What's that? Some other show that actually came before Sonic X...so Omega and Epsilon here are not knockoffs, nor are they cameos. It's actually sort of the reverse, Sonic X seems to have 'recycled' these two robots, as you can see how similar they are in their design. It isn't even a cameo really. But here it is.
