Been long so I don't know the link.
Google is your friend though and I found them the same way.
As for whom they can fight?
Supersonic stats along with some wall level fighting abilities. Whoever you think can fit that bill.
Sousuke's suit is small arms, fall, fire and knife proof. Albeit it apparently cannot protect against assault rifle shots or above.
It's kind of sad that the adaptation very much ends before the plot gets really interesting.
BTW, did you read the few side stories which are actually translated.
On such short details some about Sousuke's past, for example.
Like I said, Rauru could have feasibly created that barrier over an extended period of time. It certainly makes more sense than a mortal sage possessing more power than Hylia's mortal avatar, control of powers or not.
ToC just means MM Link gets powerscaled to things like WW Link's level I guess.
