Reptile is Onaga. But if you mean the classic ninja style, he hangs around the outside of the living forrest in outworld.

I hear ya with rain..

Rain is in Konquest (not sure where though, I don't have the game yet).

i beg to differ! onaga was using reptiles body as a host for his avatar/soul so that he would'nt fade into non existance...and when shujinko found all the kamidogus, the dragon egg hatched...Onagas soul left reptiles body, and it killed him! (but what ever happend to the dragon that hatched?? was that onaga??)
heres what i think
notice how reptile de-evolved from game to game...in MK1 he was just another ninja...MK2 you see hes hidding somthing under the mask!...UMK3 same thing....then in 4 and 5 i mean wow what a change!!
it was like reptile was just a normal ninja once hosting the soul of onaga...and having the dragon kings soul inside him made him mutate...and when his soul left him..after all that change... it killed him!
anyway thats just what ive gatherd from the story...i just dont see onaga and reptile being the same person...reptiles ending in MKDA is null and void...the deadly alliance won....reptile didnt!! meaning he never was crowned the dragon king!!

oh and about rain...i think hes dead or somthing! i remember reading somthing about how he became general of edenias armys or something and was killed....dont know how or by who...but what i do know is he had some hand in helping Noob saibot kill goro...because in konquest...rain needs goros shokan dagger!!! hint hint! and says hes not gonna give it back to him!! wasnt that what goro was killed by nood with...a dagger? i could be wrong!!
but anyways, like i said i think rain is dead now...just like kano, sheeva ect....sad isnt it!

WTF are you smoking? Onaga didn't take control of Reptile until the egg hatched, thus, from Reptile's MK:DA ending "His body was twisted and transformed". Reptile is probably still alive, seeing as if Sindel's ending is true, she took Onaga's soul (essance) out of Reptile, and into Onaga's orginal dead corpse and killed him that way. Reptile was probably just in a weakened state.

im smoking pot...right now as a matter of fact...what are you smoking...cause you failed to notice i said its my oppinion man!...its what i and i alone think!
im just saying reptile IS NOT ONAGA! hes just not... nuff said! onaga is onaga and reptile is reptile...not the same cat...and no reptiles ending DIDNT HAPPEN...and wheres the freaking dragon that came out of that huge egg then mr smarty pants huh? huh? J/K...for all we know that was onaga!! POINT BEING WHO KNOWS! its all speculation friends! dirty nasty rotten speculation! NOTHING MORE!
so now we are right back where we started...wheres reptile...well hes ether alive or dead...gotta be one of the two!!! who knows!?

Reptile's MK:DA did happen and Onaga used his body as a host for his return.
Below is where Reptile is at the end of Mortal Kombat: Deception (it contains spoilers contained in Sindel's ending)

If Reptile ending didn't occur, why Reptile (with his human form) appear in Sindel ending after Onaga soul leave his body?

Yeah that's exactly what I said.
Reptile's ending from MK:DA had to have happened for Sindel's ending to work.

In fact, I asked to DarkCarnival17... I didn't see yet your post...

we'll then sindel's ending will not happen then!!!...i hate when people play the game and think every single ending actually happends!!!
reptile did not beat quan chi and shang tsung no one did...and that means reptiles ending DID NOT HAPPEN GUYS!
nd if my theroy isnt correct about reptiles de-evolution...then WHY DOES reptile appear in human form AFTER dragon onagas soul is removed!?!? think about it... your oppinions hold strong almost rock solid points! BUT take into consideration...his did win the last tournament you gotta win it for YOUR ending to actually happen!! quan chi and shang tsungs ending DID happen (more or less) and this game is the aftermath!!
but i wasnt trying to debate on a topic none of us are sure of! so let it rest!

The dragon egg was Onagas essense and according to prophecy when the egg hatches the Dragon King will return and Reptile just happened to be the one there at the time, thus Reptile became Onagas vessel... the same as Damashi was an avatar for Onaga Reptile was needed to give Onaga the primal Reptilian Dragon like body that he needed... So basically the Dragon in the egg was nothing more than Onagas essence being reborn...

Basically, just PLEASE understand, Reptile's ending DID happen. Not ALL endings happen, that is infact true, but it is known that this one is infact true. Back after DA was released, members of the MK team even said Reptile would change into a dragon type looking thing. HELLO!? lol And yes, Reptile didn't beat Shang Tsung and Quan Chi. Onaga did, BUT Onaga is still using Reptile's body, and that won't change because it IS fact.

very interesting!! i can believe that! but one question...you could clearly see a dragon in that egg man...WTF happend to that dragon?? and do you some what agree with my theroy of his de-evolution through the years...considering you said the dragon king had to give reptile a dragon like body!? and whut if damashi once guided reptile like he did shujinko?
by the way around how many years does this story take place...from MK! to MKDA? is it 5-10 or 10-20? cause sub zero HAS AGED!!!

I think it was said somewhere that he's been aging because of the Medallion he has.

DUDE SOME ENDINGS COME TRUE IN PART OR FULLY AND REPTILES DA ENDING NEVER SAID THAT HE BEATED THE DEADLY ALLIEANCE
So sindels ending will probably be true or half true and remember that when an ending states something of the past it is true EX:

yea you are right some ending do come true in part now that i think back!
cause im sure lui kangs ending will come true as well!
heres some real speculation! is onaga goros daddy? he was half human half dragon!!?? or is that just a stupid thought!?

Basically, in DA some endings were only partially true. As in subzero's ending. Frost was gravely injured in her own ending, and was carried off by sub in his as a continuation. The second part of his prob is not true. The same with reptile. Part happens. Part does not.

True, I guess the endings are really all relavtive to each other, depending on what you wanna believe.

i agree!
