I HAVE EVERYTHING EXCEPT ONE MISSSION TO COMPLETE AND its one of the last missions where you have to defeat at least seven heartless and i cant beat the final one, he is to much of a beast. but alright i have two questions... is there a secret ending, and how do i defeat this beast?

So, there is no secret ending for this installment sorry, and for the Dustflier (beast) i would recommend the Twilight Blaze keyblade and all high jump links attached. Avoid attacks and nail 2 or 3 combos a time. There is a quite good strategy in kingdomhearts.wikia.com...head over and cheak it

nope, there isnt,

 

ok, basically, have some high level cura's for when you get hit, and a high leveled glide,

he has an attack pattern, jump up and land down to create a shockwave, then it will preform one of three attacks,

-it will lift itself up into the air and do a flip

-it will lift itself up and dash forward

-it will lift its head up and shoot several meteors into the air that will linger for a second then fire at your location

if it uses one of the first two then fly towards it and preform a combo or two, but if it uses meteor, then here is what you do

since it wont move when it uses the meteor attack, what you should do is try to position it on one end of the battle field (since i believe it will land near your current location when using the shockwave), and if it uses meteor, then fly to the opposite side of the battle field and hide behind the set of pillars since the meteors will not shoot through (or you could position the dustflier underneath the roof and all the meteors will self destruct, which is awesome)

just follow this strategy for a long but some what easy victory, but i would suggest you have beaten the game and purchased the zero gear and equipped it with either all ability panels or all sight panels

theres only a secret ending (regrettably) in all major enstallments. BBS has one because it can be considered KH 0.

there is no secret ending

The equivalent of a secret ending in this game would be unlocking Sora and Mickey

Mickey: Complete every mission

Sora: Fill the mission gauge up 100% on every mission.

No there is nit a secret ending in 358/2 Days. Nomura said that the next scecret ending will be in Kingdom Hearts: 3D

Heres a quick tip: when he lands and shoots out fireballs go behind bushes on the wall of the station and you wont take damage
