Knuckles and Chaos...who's fight was it really?

This is one of my pet peeves about the story in Sonic Adventure: The Role of Knuckles.
I get that Sonic's fight with Chaos in a way was Sonic's way of facing his fear of water, because Chaos was essentially made of water. Yet, he didn't seem to show it that much.
But when you stop to think about it, the story was really about Knuckles, and how his people disappeared off the face of the Earth. Think about it, Chaos is responsible for the destruction of the Knuckles Clan. Knuckles' people, his ancestry, his legacy. The very blood that courses through his veins. To find out that the very thing that destroyed your clan is alive, wouldn't think think mixed feelings of fear and anger would be in Knuckles' mind? Don't you think he'd want to try to stop it from destroying again?
Then the sequences with Tikal; Knuckles didn't even seem to care when he saw the other echidnas.
And the fight with perfect Chaos, I get that it's Sonic's game but don't you think it should've been Knuckles' fight? Don't you think that Knuckles should've been the one to turn into Super Knuckles and fight Chaos instead? Honestly, Chaos killed his people. If you had the power to destroy the monster that killed your race and you were the last of your kind, you would want to destroy it too wouldn't you?
At least in Sonic Chronicles it seemed that Knuckles got a little more credit. But even then, it just seemed like Sonic had too much spotlight in another game that centered around echidnas. Again, I think it should've been Knuckles fight against Ix. Not Sonic's.
So what do you guys think? Do you think Sonic is showing up Knuckles by being the hero instead of the spike fisted echidna?

Well, the problem of course is all in the name. SONIC Adventure. Since Sonic was the star, everything had to revolve around Sonic, at least the hero stuff. Also, once the Genesis era died out, Knuckles and Tails lost all their powers. They even forgot that they even HAD super forms.

Naturally since Sonic was the star of the game, Knuckles had to remain platonic towards EVERYTHING. Tikal wasn't really important. His ancestors, his past, the being who destroyed his entire race, all worthless to him.

They used the excuse of Knux's one-track mind to get him out of the way and just have him restore the Master Emerald. Once he did that, that was it. It's not Knuckles Adventure (even though half the time it SHOULD be), it's Sonic Adventure.

I get that it's all in the name, but it bothers me that Knuckles is completely apathetic in the scenes with Tikal.
But the thing is, if the plot is supposed to center around Sonic, why even bother to touch base on Echidna History and culture?
It really should've been Knuckles' Adventure, and it should've had Knuckles as the hero. And you're right, Super/Hyper Knuckles and Super Tails have completely been forgotten about.
There's certainly no lack of different super powered forms for Sonic however. (Which is why I don't see why they can't bring Hyper Sonic back) And it's not like Sonic's the only one with a super form. Blaze, Shadow, Silver, and Imperator Ix all have Super forms. So I don't see why Knuckles and Tails shouldn't have one.
But I think Sega just wanted to create a hit Sonic game, after several failed attempts (like Sonic X-treme which sadly bit the dust before it was completed) for the Dream Cast. It's not like they cared about Knuckles, and personally I liked learning more about his history and past, which was previously more mysterious and open to interpretation. And this whole "Technologically Advanced" civilization that Ken Penders one of the previous writers of the Archie Sonic comics just didn't cut it. It was cool at first, but I liked Sega's version better because it was an official plotline. (Fleetway seemed to interpret the echidnas as being technologically advanced as well, or at least far more evolved than the other creatures of the time, with Guardian robots. In Fleetway I think it was more that the Echidnas were just the dominant species and highest evolved creatures at the time.)
In anycase, it just seemed like the game was meant for Knuckles, and this whole "one track" mindedness to me seemed a little OOC. Even in the original games Knuckles was the guardian of Angel Island, not just the Master Emerald.

It's called SONIC Adventure. If Knuckles was the star, it'd be called Knuckles Adventure, followed by Knuckles Adventure 2. xD

But the story of SA1 was about the monster that killed the Knuckles Clan, the entire civilization of echidnas who Knuckles traces his ancestry back to.
Yeah, I GET that it's called Sonic Adventure. But it really wasn't about Sonic at all, other than he just got caught up in the mess, and the monster happened to be made of the thing Sonic's the most afraid of: Water. Even then it wasn't like he seemed all that afraid of water. He wasn't all "OMG WATER! MY MORTAL ENEMY! NUUUU!" *runs* he just acted like his typical self.
Sonic Adventure 2 more appropriately seemed to center around Sonic.
But I really think Knuckles should've shown more emotion toward the echidna civilization, I mean, unless he's used to seeing ghosts of other echidnas like Tikal. There were the ghosts of Sandopolis zone in Sonic and Knuckles, but they didn't resemble echidnas.
