Sometimes these things just tend to hide in plain sight. Just like ghosts. They're there you know. You just aren't looking right.
Also, for those of your curious, here's a more clear view of the photo from the past couple of comics, and who's in it; http://i.imgur.com/JKKee5F.png
Tsu is obviously first, with her older sprites! Because, y'know, that made sense to me.
Jake was a water-used, frame ex-convict. Was sort a 'rough but nice' figure, coming from a bad background but being an overall good guy. Thanks to Spekkal for helping create an updated sprite for him!
Pepper next, and this is a waaay old sprite of her from before I was over here at Smackjeeves. Though some observant readers here may recognise her body... She was an electric user, and pretty rock-and-roll. If the old RPs required a sorta main character of sorts, she's the sorta 'positive teenage hero' who'd fit well into that role. Oh, also, her and Jake were dating! I also thiiink they were owned by the same person? May be getting slightly mixed up.
Blackjack meanwhile, was Pepper's adopted brother who had... zero powers as far as I recall? Whilst he started as another generic hero type, I remember him becoming more the 'grizzled hero' archetype, being probably the only member of the group to be like 'Well, if we're fighting demons on a regular basis, should I just use this gun?' Thanks to Spekkal again for this particular sprite of them!
Blader continues to be owned by Badx, who I've actually been in contact with somewhat recently! I won't actually detail much on him yet since... well, we shall perhaps see in future. ;D
Vas there in his younger form, after he mutated and lost his arms, before he mutated again and got his arms back. It's science people! Pure genetics!
And of course, last but not least, Billie - owned by the same person as Blackjack. Vas' ex, who seemed to... get into trouble a lot actually in hindsight. She had a healing factor which really helped with that, but demons and serial killers seemed to make common acquaintance with her.
Mentioned in this page are Zippo and Knightmare. Zippo I plan to cover another time, but Knightmare? Knightmare I, uh, maaay've forgotten to put onto the original photo til it was too late for me to add him. Still, as apology, here's what the gun-armed echidna's owner is up to these days! https://www.youtube.com/watch?v=xUJfB5F7Huk
He's the one with a prominent beard. The sonic fandom is a weird and wonderful place.
Speaking of metal-as-all-hell, the demon-realm-literally-made-of-demon corpse is owned by Spekkal, so credit to her for the infodump!
