Seems I'm biased to female Dante.
Corrin's data is getting there too on KuroganeHammer and sixriver and with her projectile, Dragon Fang Shot. Its startup is frame 15 for the shot and frame 24 for the bite uncharged. Total frames for both is frame 59. This is where things get interesting since it's the reverse of Wolf's Blaster where in Wolf's case, the bayonet hit comes first on frame 11 and the bolt comes out at frame 14. If I were to consider Wolf's Blaster recovery frames, it would be just for the bolt since that's the last hitbox out since the bayonet hitbox ends at 13. Also, his is more of a projectile with a melee hitbox to Corrin's projectile and melee fusion. In this case, I'm going to split it.
So, projectile-wise, it would have 45 recovery frames while bite-wise, with the last active hitbox on frame 25, it has 35 recovery frames. As a projectile that does 4% and stuns? Okay since it trades low recovery frames (ZSS's Paralyzer) for range. As a melee hit that does 10%, okay. Combined? Probably good since there's no other move we could compare with.
Charged, it fires in frame 45 and bites on frame 85 with 120 total frames. For the shot, that's 76 recovery frames and for the bite, that's 36. Considering that it does 13%, the range, the size of the hitbox, and that it stuns, I'd say 76 recovery frames is appropriate. For the bite? It does 20% and it has low recovery. Startup is high which makes sense since it's a charged move. Alone, it's nothing special when Ganondorf can do 21% to 24% off of a frame 21 Up Smash with 19 recovery frames. Together? At pointblank, the bite is confirmed by the shot and as everyone has seen by now, that's 33%. That's a hard punish if I ever seen one.
So, impressions from the frame data? First off, don't ever use a charged DFS in neutral. In general, don't use fully charged moves ever in neutral unless you're Meta Knight and sometimes Ganondorf... Uncharged would be fine. Not particularly safe, but not particularly easy to challenge since you will need to land above or behind her or you'll get bitten. That's the gimmick of uncharged DFS, it's essentially a projectile with a melee safety net. In Corrin's case, it's projectile to melee hit while Wolf's is melee hit to projectile.
Charged DFS seems to be like a fusion of Paralyzer and Falcon Punch. That's what each part of it is when charged. Alone, they're not really good, especially Falcon Punch, but together... Hoo, could you imagine what would happen if the Capt. had a stun gun to confirm into his Falcon Punch or ZSS had a Falcon Punch to be used after Paralyzer? Well, she kind of does... Anyway, that doesn't mean you can freely use it. Like I said, it's more of a hard punish if you manage to hit that close up. The shot coming out at frame 45 is 8 frames before Falcon Punch and that's hella slow. As a projectile, 13% with a lot of damage is good, but once again, it's slow and without being able to store a charge... Y'know, this would make it more like Phantom Slash if it had a stun projectile to confirm the Phantom Knight's attack.
I doubt there's a way to confirm a charged DFS 1v1, but confirming an uncharged one wouldn't be that bad either... 4% from the shot and 10% from the bite... In doubles, setting up a frame 45 move might not be a pipe dream... Yeah... Corrin's going to be stupid in teams.
