Ryan Cooper... the day has come.

Cross drives a C6.R I know that for a fact and that C6.R is a LeMans Racing Car

But here is the thing your playing as the undercover when you hear the cop say that they caught Ryan Cooper so it's automatically not Ryan as the cop...

First thing:
SH*T! SH*T! Im on NFStheories.

Second thing is that for me its pretty clear how it is in timeline:
1. Underground (You are a noob entering into big world of SR)

2. Underground 2 (You are a boss of everyone in Olimpic City. Someone gets annoyed and tries to end your carrer, but you get back up and running. This time in Bayview)
2.1 Story behind "Carbon" (Stuff in Bayview get you into trouble, as always you want to "Own them all" so you focus on another city this time its Palmont. After time Police gets used to Street Racers, which means they have better tactics on us(In UG and UG2 no cops, because they couldnt do sh*t about fast cars). There are undercovers. It all gets messy one day. You have to run, but money you should have won was stolen. You leave your friends and for all that you had left buy a tricked out BMW)
P.S. I think that back then Crock could have been that guy who changed bags or was in that silver Chrysler.

3. Most Wanted (So, you run. It ends up you are not so smart so your new friends trick you out. You end up without sh*t, but still want to show those guys who is the BOSS.)

4. Pro Street (Mean time story of Ryan Cooper begins. A "young" and furious driver that tries to achieve something, but is scared to try Street Racing. BMW with Carbon license is car of our protagonist is just after events of Most Wanted. He is curious how Legal stuff look, thats all)

5. Carbon (After killing all those fags in Rockport, with a sentiment you try to go back to your old friends in Palmont. And (Doh...) as always it all get messy, because of "Mr. Policeman" that follows you all the way to Palmont. In Canyon accident all stuff gets clear. Cross is bounty hunter. Trap in Palmont(Before going to Rockport) was prepared by him and buddies of Cross. He was on your back all the time (Maybe even since UG2 mid-end game). Once again you "Own the city". This time our past is clear and revenge is done).
5.1 Shift 1-2 (Ryan Cooper again. In time when our hero is Street Racing, Cooper continues to own Legal Racing. Its just my opinion)

6. Undercover (In one of cuts in Carbon, Cross say "I allways get paid, just get sure I do". Im not sure, but I think that what you earned in Carbon wasnt enough. You had to make a deal with Police. Everything is messy again)
P.S. There is also "Part of deal with Cross is that I race with you" spoken by Nikki. I think that this deal was alot bigger than that.
6.1 First scene (Its like a presentation of what you are going to experiance further in the game. You enter the city with style, but still you have deal with police )
6.2 Ryan Cooper (Its just an "Easter Egg". Cooper always wanted to become a Street Racer, but never had balls to do it. Sometimes he likes to make some speed on street. This time he gets caught)

OMG. Thats alot of stuff i have written. Now feel free to correct me, because its only what I think.

P.S. And there is a possibility that Cross is your somehow Guardian Angel, but with his own picture of what you are going to do. Like your arrival in Rockport wasnt your choice. Cross had problems with SR there so he made you go there to help him (Last scene where whole blacklist gets caught).

4.1 Shift 1-2 (Ryan Cooper again. In time when our hero is Street Racing, Cooper continues to own Legal Racing. Its just my opinion)

5. Underground (After main protagonist gets clear he aint in Olympic City. This time we have anouther person that starts from scratch between people known and unknown from MW, Carbon.)

6. Underground 2 (Our second protagonist becomes a boss of everyone in Olimpic City. Someone gets annoyed and tries to end his carrer, but he gets back up and running. This time in Bayview)


7. Undercover (In one of cuts in Carbon, Cross said "I always get paid, just get sure I do". Im not sure, but I think that what you earned in Carbon wasnt enough. You had to make a deal with Police. Everything is messy again)
P.S. There is also "Part of deal with Cross is that I race with you" spoken by Nikki. I think that this deal was alot bigger than that.

6.2 Ryan Cooper (Its just an "Easter Egg". Cooper always wanted to become a Street Racer, but never had balls to do it. Sometimes he likes to make some speed on street. This time he gets caught)

2. About the police is that its my explanation to no police like it would be in real life(Maybe in Olimpic and Bayview wasnt ever such problem so Police wasnt prepared. Shit, just a little bit of imagination man:) )

Shift is too my imagination
1. So if its true what you are saying. Then Underground 1-2 is about someone other but somewhere after Carbon with Nikki in it

BTW. Which girl in UG is Vaugiere?

Edit: Made a V2 of my story with UG happening later.

Im on my way to introoduction board

OMG. Now you failed. I wrote about first Palmont visit right after owning Bayview not Olympic City...

And in Wiki you can read that in UG2 Nikki leaves Caleb and joins us. So this means that its right before Palmont first visit (Where Nikki helps us grow), but then you run to Rockport without her. When you go back she is yours

Edit: Even in "accident" with police cinematic with Vaugier you can see that she is made to look like young girl.
Edit2: And F*ck you x2! It all makes total sense with you in Undercover. Cross wants his officer job back! By making a deal with him you help him get back! YES! Im genius! No more story questions!

Consolidated Timeline:

1. Carbon Flashback- Darius gives Player his Supra, pays off cops, frames Player, and gets away with it.

2. Underground- Player arrives after discovering the police are after Darius (due to Mafia connections through David), ditches Supra and ends up beating the Eastsiders.

3. Underground 2- Caleb attacks Player; Player goes to earn more money to replace what he lost and just for racing's sake. Ends up discovering Caleb's identity and beats him.

4. Most Wanted- Wanting to tie up loose ends, Player moves towards Palmont and buys an M3 GTR to do this. Stops in Rockport, where Razor pink slips the BMW. Player races to get his car and wins.

5. Carbon- Driving down to Palmont through Lookout Point, Cross attacks and the M3 is totalled. Darius goes back and plans to use Player again. Player beats him and gains the wealth of Stacked Deck.

6. ProStreet- Using his newfound wealth, Player envisions and provides funding for the ProStreet competition by getting sponsors to support it. Money for sponsors earns Player a profit and he attends the competition.

7. Undercover- Player uses extensive contacts to plant Sal in the FBI, organize races that Sal wins, and make a profit through the whole ordeal. Sal slips away afterwards. Ryan Cooper gets arrested in the mean time.

8. Shift & Shift 2- Funds NFS World Championship and other races in the games. Sal goes incognito again and brings the winnings back.

9. The Run- Player uses massive wealth to organize the Run. Makes at least a $280M profit.

10. Rivals (WiP)- Player is somehow backing/funding Zephyr's attack on law enforcement

OMG! This is so wrong!
-Undergrounds and Most Wanted+Carbon are "heroed" by two different persons.
-Pro Street looks to be between Carbon flashback and Most Wanted. Our protagonist thinks for a while about going for legal racing(Blue car with Carbon license plate is actually Supra) and maybe he changed his Supra to GTR in those races(GTR is a Track car, Street illegal!)
-Undercover Cooper doesnt have to be arrested, just like this. This accident can be only one-timer and maybe costs Cooper some "POINTS" xD
-Shift and Shift2 dont have story. So these games are out!

With The Run this can actually fit in! (Its long time later, supercars are new "Street racing" cars, main protagonist owns every city in US). But it only makes sence for us. I bet that story creators didnt have this in their minds

but what with the nissan you get in prostreet? The first car you driving in NFS Prostreet.

NO! NO! NO! Pro Street protagonist is Ryan Cooper, not our "blured face" guy. In Pro Street he only appears as a "Small blue car with CARBON lp." Which can explain where from he got his M3 GTR.
