OOC: Actually Charon, that moveset is as good as a Combusken of that level can have without TM/Breeding assistance. ^-^ Oh, but Combusken doesn't learn Flamethrower by level up. Only Torchic does (At level 43). But don't worry, you can get a TM for that from the Mauvile game corner, and failing that, Blaziken's signature move Blaze Kick is a quite decent substitute. ^^ Anyways, the possible movesets that I can come up with at the moment are;
Set 1:
Item: Leftovers/White Herb/Liechi Berry/Salac Berry
Moves:
Brick Break/Sky Uppercut
Flamethrower/Overheat
Rock Slide/Earthquake
Swords Dance/Substitute
Pretty much a standard set, Flamethrower and Overheat to take advantage of STAB and Blaze, and Brick Break or Sky Uppercut for STABed physical damage. Swords Dance is there for fast Attack boosting, because Blaziken simply doesn't have the defenses for taking proper advantage of Bulk Up, while Substitute is there for blocking status moves from slower attackers as well as taking advantage of your opponent switching or using stat boosting moves to put up a protection while the last move is basically just your average hard-hitting physical move. Earthquake for getting the best base damage while still enjoying some type advantage, while Rock Slide serves to counter Blaziken's weakness against flying types. On the item front, Leftovers are always a reliable choice. However, if you go with Overheat for the fire move then White Herb will grant you an additional full-power hit without switching. Also, if you go with Substitute then a Salac or Liechi Berry can grant you an additional stat bonus for sweeping. However, berries and whatnot are a real pain to get ingame so Leftovers are probably the best way to go.
Set 2:
Item: Choice Band
Moves:
Brick Break/Sky Uppercut
Flamethrower/Fire Blast
Earthquake/Rock Slide/Focus Punch
Earthquake Rock Slide/Focus Punch
Meh, standard CB sweeper set. Blaziken might not be the best pokémon for this but it should still do quite nicely. Basically the only idea with this set is to be able to deal as much damage as possible to as wide a selection of opponents as possible. Focus Punch is there as a prediction move as it, combined with STAB and the Choice Band Attack bonus, can deal some devastating damage to practically anything except for Ghost types. However, since it requires your opponent not to damage you and always strikes last it might be best used against other human players.
Set 3:
Item: Scope Lens
Moves:
Slash
Blaze Kick
Double Kick/Sky Uppercut
Focus Energy
Yay for critical hits. As you can probably see this set is basically just bent towards dealing as many critical hits as possible to rip through opponents' defenses. However, because it relies so heavily on luck, success with this set is always up to chance. I wouldn't go for this one myself, but I figured I should offer as much choice as possible. Double Kick is added as an option for Sky Uppercut because it strikes twice and hence, you have twice the chance of scoring a critical hit.
Set 4 (May require breeding):
Item: Leftovers/Salac Berry/White Herb
Moves:
Rock Slide/Earthquake
Flamethrower/Overheat/Thunderpunch/Swords Dance
Reversal/Focus Punch
Substitute/Endure/Swords Dance
Standard subrever with some additional thoughts. Focus Punch is an option for Reversal in case you go for Substitute (Obvious reasons) just in case you manage to keep one up. Revers can be tough too, and to that end, Endure and Substitute let you drop your HP in a controlled manner while Swords Dance lets you get an additional boost to the damage, although you won't be able to get Reversal to reach the very best of its attack power. For the physical move in the first slot, I'd reccomend Rock Slide unless you go for Thunderpunch or one of the fire moves for the second slot, because Earthquake would leave you unable to deal damage to pokémon from the Ghastly evolution line. Concerning Thunderpunch, I basically just added that in case you're Gyarados paranoid. For items, Salac Berry lets you maximize sweeping potential while White Herb provides the usual aid for Overheat and Leftovers make for a generally useful choice, although you should never put those on a rever as they'd cut down Reversal's power over time. :\
Yayness.

Hiro continued trotting ahead of the group, sulking and forcing his attention to stay on their environment. The fools...didn't they realize how many dangers could be lurking about? Granted, the fire type didn't see anything suspicious amongst the bright, pastel coloured houses, but that in itself was suspicious, no? And besides, who knew what could-
The Houndoom stiffened in the middle of his thoughts, freezing onto the spot and staring intently towards one of the houses in the distance, and sure enough, just barely visible in the distance, there was someone there...the dog pokémon's eyes narrowed as he peered at the small glimpse of a slightly shabby tan-coloured overcoat and the unkept, faded brown hair which hung about the person's head in unruly tassles. As his suspicions just seemed to become more confirmed by the minute, Hiro's back arched defensively and his expression turned grim, a low growl escaping his mouth.
Yikari, who had happily joined into singing 'The wheels of the buss go round and round...' suddenly paused, giving his long-time companion a wary look as he knew this particular expression all too well.
"Hiro?" he asked, walking up to the Houndoom and crouching down beside him while carefully placing a hand on the dog pokémon's head, "What's the matter?"
{It's him...} Hiro replied in a voice so low that few others could probably hear him, staring intently at the quickly departing figure until he dissapeared out of view completely, {I didn't catch his scent but I'm positive it's him.}
Yikari frowned, quite an uncharacteristic expression for him, "No..." he said in an equally quiet voice, "It can't...he wouldn't have gotten past...not with all these restrictions...maybe you made a mistake, Hiro?"
{Maybe...} the Houndoom admitted, giving off a slight sigh, {But I'm usually not that lucky. Let's just get this presentation-thing over with and get away from here as soon as possible...}
The boy took a thoughtful pause, sighing in forfeit at last, "For once...I agree with you Hiro." he replied, "Let's go." yikari rose back up to his feet again, reuniting with the group. But his cheerful mood seemed completely gone now as he walked forward in complete silence with a thoughtful, almost somber expression on his face.
OOC: Pwhee for foreshadowing. The dude whom Hiro spotted shall make his actual appearance later. This just struck me as a handy spot to introduce him...well...sort of.
