Only in the Cobra Escape Armour and Hyena datafiles.

That first clue has me stumped I don't know who was ret-conned in comic packs apart from Nemesis Enforcer or whatever he is now named.

Sorry, Sundance. It wasn't , but is a chara with a Muticon (I don't consider this a NEW hint; it was implied by the fact of appearing in BAF), so the options are reduced.
Ironblood, I'll try to explain the comic pack thing after the right answer.
Next hint: I have debts.

Copperhead? If so he was used by DDP no idea still about the comic pack and I think he was used once by Marvel UK in Doppelganger.

Yes, it is (sorry, I haven't read the DDP stuff yet).
The comic pack I was talking about was the /Shipwreck/Polly one. I think the story shown in it happens shortly before Serpentor's first appearance. Still, despite 's DDP appearances, we could still say the comic pack retcons him into the classic era, right? (so weird he didn't appear even when Python Patrol appeared)

First clue: I was born in the Cayman Islands
