Ultimately you're gonna want to make this match memorable; you want to milk the fact that its a rare fight, perhaps the only fight like this in the game, by making it a little tougher, but don't just give 'em good stats and a boatload of HP.
I wanted to make special emphasis on this part of Kaust's post, especially because you're doing a one-on-one final battle. Final battles must be memorable since they leave an impact on the player. It's the last impression they get from your game, you MUST make it memorable.
Give your character a special skill or make the final battle require the use of strategies different to all the other bosses, and most of all make it VERY important to the story.
Just to cite an example, MOTHER 3 used a one-on-one battle as the final battle and with a very good reason considering who the final boss is.
