October Novel Prep Challenge

My current project is a great case study on conflict and antagonists, so I'll put the question to the crowd. Who is my antagonist? Here are your choices:

Character #1 (a slimy used-car salesman named Greg who ran a local American-Idol style contest on the side) owes my protagonist prize money and a recording contract. He's not paying up, and it's interfering with her dreams of pop stardom.

Character #2 (a goddess named Erecura) offers my protagonist the fame she desires, but she must use her powers of persuasion to recruit Erecura's nemesis, the goddess Danicea, to enact vengeance on Greg by cursing him.(Curses are not permitted among their kind, so Erecura is trying to get Danicea in trouble.)

Character #3 (a goddess named Danicea) doesn't want to curse Greg because she'll get in trouble for casting curses, so she resists my protagonist's efforts to persuade her to curse him.

Character #4 (my protagonist, a singer named Octavia) was born and raised Catholic and doesn't believe she or Danicea or anyone but God has the right to cast judgment on anyone. She's struggling with conflicting desires: the desire to achieve her dream of stardom versus her desire to be a good girl and comply with what she knows is morally right.

Sooooooooo... the plot centers around Octavia's efforts to convince Danicea to curse Greg so she can keep the stardom she's gained through Erecura, who keeps threatening to take it all back away again.

Who's my story's antagonist, and why?

I'm hoping to get opposing opinions on the matter so we can all see how an analysis like this might go.

Cheers,
Michelle
