Void wave is an unofficial Avengers wave:
Avengers - Vision, Black Panther, Namor, Justice
Avengers ally - Namorita
Avengers enemies - Power Princess, BAF Void
Wild Card - Crystar
Skurge wave - you can fudge an Avengers theme:
Avengers - Iron Man, Wolverine
Avengers Allies/adversaries - Phantom Rider, Werewolf By Night
Avengers enemies - Dark Avengers Spider-Man, Enchantress, BAF Skurge
Wild Card - Warbow
Just guessing -
Zabu wave seems thrown together from a planned Avengers wave and an X-Men wave that were cancelled:
Avengers - Iron Man, Thor (Black Winter), Ikaris (Avengers ally), Red Widow (Avengers enemy)
X-Men - Wolfsbane, Cable, Ka-Zar, BAF Zabu
At the time I speculated on the other site that the EOV failure switched some things up and planned Avengers and X BAF waves were affected. I thought (and still do) that there was a planned Ghost Rider Retro Card wave to coincide with the EOV shipping. The EOV failed, the Retro Card wave was cancelled, and they had some supernatural characters that needed to go somewhere, so they created the Strange Tales wave, which only had one character that was actually tied to any of the Strange Tales comic books.
I think the planned waves would have included, but some characters were pulled into the cobbled together Strange Tales wave:
X-Wave: Wolfsbane, Cable, Ka-Zar, Strange Tales Hellverine & Bloodstorm, BAF Zabu plus 2 other characters that ended up elsewhere.
Avengers Wave - Iron Man, Thor (Black Winter), Ikaris, Red Widow, Strange Tales wave Moon Knight & Brother Voodoo, green suit Wal-Mart Quicksilver. Or maybe Lockjaw as the BAF and Crystal as part of the wave.
Ghost Rider Retro Card Wave - Lilith, Dracula, Blackheart
