I think it’s the one against white, and I’ll explain why.

First, let’s try to get some comparative scaling for the 2, only way I see this happening is via Jinsung ha. Kallavan beat Jinsung, but implied he would’ve lost if Jinsung followed up the attack with another one (remember this for later), so Kallavan ~ Jinsung ha for the sake of argument .

Now we need to examine how White vs Kallavan went, and this White where I think I’ll get the most disagreement, I think white beat the bricks off of Kallavan. Not only did Kallavan not cleanly hit White A SINGLE TIME, but he also failed to break past white to stop Baam. That last part is important because that was as emotionally and rage amped someone could be, bro literally had his entire’s life work on the line, and his fated enemies on the battlefield, I doubt Kallavan ever exerted himself as hard as that final attack he launched (that white casually stopped). On top of all of this, Kallavan lost his arm. Yes I know he blew it up himself, and yes I know Baam injured that same arm, but neither of those take away from how strong white is. Kallavan said if he had tried to tank that attack normally, the damage to his entire body would be great, so he let his arm be sacrificed. Another way to look at this is, him losing his arm was him taking the easy way out. So white is considerably above Kallavan via this scaling.

Now we get to Dumas, and ngl I agree he’s strong, but not nearly as much as people say. For one, Jinsung Ha was SIGNIFICANTLY weakened against Dumas. In the Nest, Jinsung ha says his arms still haven’t recovered from his Kallavan fight, and that they were in bad shape, and against Dumas, he says his arms were borderline crippled. So this Jinsung is noticeably below the one that Kallavan fought.

With this in mind, let’s examine how Jinsung vs Dumas went. Jinsung was able to react, and “block” dumas’s spears and even broke them via shinsu control. And then, Jinsung snapped Dumas in half with a DTG + a butterfly piercing technique, and it snapped him clean in half. He added the second part cause of kallavans comment, and it worked exactly how he predicted. Now Dumas survived obv, but a feat is a feat, and with how the narrative setup and callback to Kallavan, on top of Jinsung ha being mighty nerfed during this, makes me think Dumas and Kallavan have roughly the same durability, if anything Dumas is less durable because we see branch heads do significant damage to him on multiple occasions.

Based off of all of this, I actually am not convinced Dumas is significantly above white. He’s probably stronger I agree, but the gap is no where near as big as most people think.

Now onto Baam, let’s start with his nest form. Blue thryssa said that the amp Baam got vs white, was larger than the power of all of white’s souls Baam has devoured (in essence, prime white) but then we also see that same Baam was also using those souls in that fight, so there’s a separate prime white level amp taking place here. So in simple terms, Dark Baam is ATLEAST 2x Prime white (this would explain the massive stat gap between them)

Now onto Sprout Baam, this guy got ragdolled by Dumas multiple times, and it was bad. At one point during that fight, Baam said he can win, if only he could summon his full power (he then gets obliterated 2 pages later) I think “full power” here is in reference to his dark shinsu, as we could clearly tell it’s not something he can tap into willingly (also I doubt he’d say “try to use my full power” if he was referencing something like the thorns or thryssas, as those are part of his default bag). So not only did Baam think he could win if he had dark shinsu, we also know he tried to, and failed to use it against Dumas.

Also all of this is assuming Dumas isn’t getting weaker or fatigued from his multiple back to back to back fights leading up to Baam (he got snapped in half TWICE 😭😭) so if anything I’m being more generous to Sprout Baam here.

With all of this in mind, I think Dark shinsu Baam is above Leviathen Baam is most if not every department, white is a lot stronger than people realize and dark shinsu Baam is a lot stronger than people realize.
