Coeurverse Characters Equal Canon

Since it was brought up, I'll point out that Oscar in this story is still Volume 4 Oscar. He is the Oscar who, in an unarmed training spar with Ruby, couldn't even get his aura up in time to defend himself. Ruby, who has been shown to be very much handicapped when she doesn't have her weapon to hand.

Yes, when he is using Ozpin (or Ozpin is helping him) he becomes much, much stronger – able to face off against Hazel on even ground – but that isn't what is happening here. Much like Ozpin wanted to train Oscar in the show and thus had him sparring with Ruby, he wants to have Oscar grow here as well. Ozpin isn't going to `help` him in spars against Cardin or anyone else.

Oscar, like Jaune, has potential, but this story is still IN the six-month time skip that the show put us through. Oscar is a complete amateur who is literally a helpless boy relying on Ozpin to help him cope with any real threats.

We obviously have no idea how strong Sienna is compared to Tyrian in the show. That was noted to me after last chapter, so I'll say it here that I agree with that. It may be that Sienna wouldn't be this useless in a 3v1, but we just don't know and if Tyrian could take on Team RNJR and Qrow at the same time, I'm going with the idea that he's really strong – since Qrow is (I believe) called one of the strongest huntsmen of his era.

"Sienna Khan would not go down so easily."

Adam stabs through chest once. Urk. Dead. Yeah, you didn't exactly have the best showing in canon, Sienna.

I do want to quickly address one thing that concerned people, i.e. Jaune's strength. I'll make it short because I don't want to spoiler anything. Basically Jaune in the real show managed to beat a single Ursa, although he would have died doing it if it weren't for Pyrrha. In this he fought five Ursa, and was doing perfectly fine until they hemmed him in. So yeah he is stronger here, trust me. I know in the show he managed to behead it with a single strike, but keep in mind that was with a run-up, a charge attack. He struck it once last chapter when he was already knocked to the floor – that doesn't have the same swing lol.

Also last chapter was actually his FIRST Grimm he ever faced. As he missed initiation, and in fact his "only" other fight was vs Cardin. Of course he trains with Neo, but can you imagine trying to figure out how strong you are when the person you're training with is so far ahead of your level?

What I'm trying to say is – we haven't seen how strong Professor Jaune Arc is at the moment, he beat Cardin (and as much as it was a gimmick – it was still a crushing win) – so he's clearly stronger than canon Jaune. So he can't beat five Ursa alone, but he hasn't had a chance to show what he can do 1v1 a Grimm. Jaune isn't aware of his own strength either, all he sees is himself losing to Neo and thinks "Man I'm weak." - but he hasn't actually seen how Neo is compared to others her age.

Also there's a hint here – remember how long Yang lasted in a fight against Neo? She was trounced – and yet it's Neo who is training Jaune. So trust me, he isn't and won't be underpowered.
