it's not downplay it's the truth, Madara loves to fight and will do anything to get the most out of it, you don't think a non uchiha suddenly popping up with a perfect susanoo isn't going to peak his interest?
Yes, Madara loves to fight people who are strong or have something extremely rare like the Eight Inner Gates, Kakashi has nothing he hasn't seen or doesn't himself have.
There's no reason for Madara to not start with Limbo here, he did it against Naruto and Sasuke and used it constantly throughout their fight, Guy was an exception, not the rule.
Hell, he was even considering using Limbo against Kakashi and Ten Tails removed Obito, but decided against it due to Obito having the Rinnegan, this clearly shows that he's more willing to use it than you're arguing.
Why would Madara care about Perfect Susanoo? It's something he's had for decades and he clearly considers obsolete since he didn't use it once after becoming the Ten Tails Jinchuriki.
Don't see how you can compare his interest in the Eight Gates to the Perfect Susanoo, one of those he himself has had for many years, the other he doesn't have and has arguably never seen and only heard about.
He knows how it works but does not know how strong or fast it is, the Kamui he encountered was ridiculously worse and bottlenecked by the fact they were being used by two different people, this Kamui isnt slower than him.
I'm confused on what you even mean with this, prove Kakashi's Kamui got faster when he gained DMS.
He knows exactly how strong it is, as I said, he's used it himself and has seen it used several times before, he even saw the effects of Kakashi sniping off the Gedo Mazo's arm with it, so let's not act like Madara's clueless, he arguably knows just as much about it as Kakashi does.
Naruto and Sasuke appearing IS later in the fight (the fight referring to Might GUY VS MADARA), He resorts to Limbo after being overpowered by Naruto and being surprised that he casually kicked his TSB ball away, after getting fodderized by Naruto's lava rasenshuriken he takes Naruto and Sasuke seriously and does whatever he can to avoid getting hurt or sealed, in character this Madara's first attack is TSB.
No idea why you're not considering them separate fights, Madara used it instantly against Naruto and constantly during his fight with Naruto and Sasuke, this is factual.
If you consider what Naruto did as "fodderizing", then you could also consider what Guy did to Madara "fodderizing" as well, and yet he didn't use Limbo against Guy once, why? It's pretty clear why, he wanted to enjoy his fight with Guy to the fullest, context matters but you seem to be ignoring it entirely.
nope this is the Madara after Absorbing the Tree but before going after Kakashi, we don't include Obito's sharingan on Madara's page,if Op wanted Madara with Obito's Sharingan it would have been mentioned as it's not part of his standard Arsenal
What is this based on? SBA is the latest or strongest version of a key, the strongest/latest version of this Madara is when he has Obito's Sharingan right before he takes back his second Rinnegan.
The reason Obito's MS abilities aren't part of Madara's abilities is because he had Obito's Sharingan for a very short amount of time and never used it in a fight, only to teleport to the Kamui dimension and leave, it doesn't change what I said though,
per SBA this is Madara with Kakashi's Sharingan.
But whatever, the OP can clarify if Madara has Kamui here or not.
