I don't know too much about this line (it seems like this is a collaboration beween BBTS and Fresh Monkey Fiction,
but its already got three absolute all-time favourite characters (pictures courtesy of Toyark);
Bulletproof (C.O.P.S)
The Tick (the picture is, I believe, an SDCC variant, there is a standard version being released).
and last but not least, Madman
There's also Rocketeer, Chairface Chippendale (The Tick), Grendel and some others I'm not as familiar with.
I remember seeing the Big Blast line in Toyfare magazine back in the 90s and being gutted that I never actually saw any of them in any shops in the UK. The Legendary Heroes line was a decent attempt, and less said about Shocker/GBJR toys the better. Hopefully this line has legs, I don't mind paying import prices if need be (The Tick has been listed on at least one UK site, so I think that there will be chances to get them without importing).
It might just be me getting excited, but seeing Madman in particular has grabbed my attention like nothing else so far in the various SDCC previews I've seen- he's one of my special 3 non-Marvel/DC comics from the early 90s (Madman, Bone and Concrete).
