1. 0o Sonic Universe? .. What is this Sonic Universe you all speak of!? When did it come about? You know, I heard WHISPERS of a "Sonic Universe" back when I was falling off the bandwagon *coughduetoaburninghousecough* and.. 0o it has become reality! Woah!
No idea if what your talking about is the same thing, but as far as I can piece together, Sonic Universe is a supplement comic that explores the side-characters of the main plots and has them in usually less serious comics. It tends to fill in the gaps of what happens to characters when they go off-panel in the main series =)
That's what I can gather so far!
