So I have a few of ideas on what Juane's semblance may be. One of them is the idea that he has a healing semblance that either heals him or heals others. The first one is based on when Pyrrha first unlocks his aura and his cut heals almost instantly heals and the second one is me just basing it off his personality of wanting to help others. I can see the former as being more likely then the latter because there's less assumptions that I have to take for it. The first one could be argued away though since they do say that aura heals people.

My other idea is based on when Cardin goes to punch Jaune and Cardin gets knocked back. I think this could be Jaune having a limited force field like semblance, kinda like the semblance I gave Tai in my Raven story (shameless plug). This also kinda comes from the idea that Jaune wants to protect others like the healing semblance. The other idea that I had was that Jaune has a semblance that's a mix between the Inmovable Blob and the Unstoppable Juggernaut from Marvel comics. Yeah I know its pretty out there and can sound overpowered but for the first criticism I agree and for the second one I think its only overpowered if you make it that way. It would probably take a lot of energy to activate the semblance and to keep it running. As for the the unstoppable force part Jaune would have to build up momentum to become unstoppable. If he were to be restrained then he would not be able to use his semblance like that.

My last idea for his semblance is based on what he is based on Joan of Arc. So she was an exceptional strategist and since Jaune is known as the strategist of the group it his semblance may relate to something like that. Maybe he has an ability to find a target's weak point with something like the Legend of Zelda's z-targeting or he is able to plan out a battle like Midnighter from DC comics. Those two ideas aren't based on what we have seen in show but more of me predicting that Rooster Teeth will see what the fans think and do something out of left field to just keep us guessing.

Well that is my thoughts on it. What do you think?
