Just randomly had a new thought of who the rabbit could be that I don't think has been suggested yet...

Spoiler for idea:

Loki, simply put in a sense he was in Blue Pegasus before and maybe made them a promise or two like with Grey last arc. Plus having Lucy fight her own strongest spirit would be the most troll thing I could think of happening here and Lucy getting at least one rediculas fight per arc is almost an unwritten rule.

Just think of it Lucy ends up having to fight the Rabbit and the tries to summon Loki to defeat the rabbit only to have it not work at all... if she's lucky a good spirit would appear in his place but if unlucky she could end up with Plue on the battle field. Then only to see glowing fists on the rabbit and realize Loki is her opponent.

After all he hasn't been seen since the second time jump and for him thats kinda odd.

Plus Lucy was the member on Fairy Tail to really notice the Rabbit on day one... hence why I'm thinking the two of them may end up being the ones to fight one another. I don't know guess I'm saying it could be sly foreshadowing of an upcoming fight between them since half the cast already has the fights foreshadowed.

Now not saying this is my guess who it is, just a random thought... until I had this thought I was thinking it was Richard/Hoteye but now I'm not so sure.
