#o!soap

Classic vs. Reboot: o! = Original, n! = Reboot

o!Soap is the higher ranker between him and Ghost, while the roles are reversed between n!Ghost and n!Soap

Roach doesn't exist in the second timeline

o!Gaz has no full name listed, and is noticeably white. n!Gaz is known as Kyle Garrick, and is black

o!Price has a more posher accent compared to n!Price. In fact about everyone has different accents, Ghost having the strongest difference in my opinion

o!Price is mentored on how to shoot a sniper well in ghillie suits by MacMillan. n!Price mentors n!Gaz on the exact same thing also in ghillie suits

n!Soap is shorter than o!Soap. n!Ghost is taller than o!Ghost.

o!Ghost is more extroverted, friendly, and dependent. n!Ghost makes notably darker jokes, is more introverted, less friendly, and starkly independent

o!Ghost has black hair and green eyes, while n!Ghost has brown hair and brown eyes

So far.... Gaz, Soap, Griggs, and Ghost are all dead in the original timeline.

During Shepherd's betrayal Shepherd does the dirty work himself, and successfully kills Ghost, alongside Roach. Graves does the dirty work in Timeline 2, and fails to kill Ghost

Alejandro Vargas and Philip Graves have similarly named characters in the 1st Timeline, but the relations between them is thin to nothing. Alejandro Vargas, the cartel fighting member of Los Vaqueros has Alejandro Rojas, a cartel enemy to Soap's team. Philip Graves has Darren "Graves" Cosgrave, o!Price's North Irish ally.

Shepherd loses his iconic red beret and mustache in the 2nd timeline (and his hair in general)

n!MacMillan is implied to be dead, having gone a failed assassination mission against Zahkaev with n!Price. Although o!MacMillan fails to assassinate Zahkaev with Price, he does tear his arm off, and survive to tell the tale. IN fact o!MacMillan never dies

n! Griggs takes more a backseat in involvment compared to o! Griggs. n!Griggs Also has a full name, Marcus Griggs.
