since Very Dumb Discourse™ exists about whether or not certain versions of this ship are valid, this is going to be THE most positive post about all versions of MegOP. refer back to this post for reasons to ship your favorite version of MegOP if anyone gets weird about it with you. now let us begin!!

G1: goofy '80s faction dads fighting each other in a denny's parking lot every week LET'S GOOO, that shit is fun as fuck. orion pax also totally had a celeb crush on megatron before megatron ruined that and shot him and his pals 😔 and there's a lot of angst you can add with megatron becoming galvatron and optimus coming back to life to see how much he's changed!

BW: it's the sheer fucking comedy gold factor of a newly minted college graduate and a terrorist dinosaur IMMEDIATELY singling each other out on a prehistoric rock and deciding to call their daily gang slap-fights the BEAST WARS, what iconic drama queens LMAOOOO. also, megatron made his final body in BM look like optimal optimus SPECIFICALLY to fuck with him, and that's just...incredible

UT: the fact that megatron CANONICALLY acted like a grieving widower over optimus after he died in armada is. amazing. never forget their absolutely insane obsession with each other that they can never EVER give up on played a direct part in unicron nearly ending the world <3

Bayverse: this is the one continuity of all fucking things that gave us the lore about megatron being prime's lord high protector. absolute galaxy brain writing from the tie-in comics. also these two would ABSOLUTELY have the messiest, nastiest, most brutal hate sex imaginable, and that's beautiful. <3

Animated: optimus being a rookie washout underdog and megatron being a super scary much older warlord is a really interesting and underrated fresh take on their dynamic! lots of fun to be had with exploring what their relationship would be like after megatron finally acknowledged him as his archnemesis, lol. also...age AND size difference ( ͡° ͜ʖ ͡°)

Prime: do i even need to say anything, i'm pretty sure that one flashback still of orion and megatronus being friends is responsible for birthing a million shippers for this pairing alone LMAOOOO. the bitter ex-boyfriends energy was TRULY off the charts in this show, it's a damn shame megatron never appeared in RID15

Cyberverse: same bitter ex-boyfriends energy but this time with dates at maccadams. megatron also dies encouraging optimus to beat the unhinged alternate dimension megs AAHH THE ANGST

IDW1: they're both depressed gay war criminals in this one who CONSTANTLY live in each other's heads rent-free and that's amazing, lmfao. also, megatron becoming an autobot means this is one of the VERY FEW continuities where it's not nigh impossible to figure out a way to give these two a happy ending together in fanon

IDW2: space date space date SPACE DATE. they were falling together and everything. megatron also LITERALLY tells optimus to open himself to him...to give him the matrix...yeah megs my dude i'm sure that's the ONLY thing you wanted from optimus "opening" himself. toootally positive, lol

G1 Marvel: megatron was SUPER fucking pissed and weird as shit about the time optimus died over a video game. it counts

Dreamwave: their first fight had megatron urging optimus to join him AND they disappeared together in a space bridge explosion once which is like, a fanfic-esque setup for them to be alone. also i'm pretty sure this is the continuity where optimus accidentally gave megatron a lobotomy, so...uh...potential for angst is to be had

SG: mirror universe!! evil crazy villain optimus with noble goody-goody hero megatron has so much potential for absolute chaos. bonus if you also bring in the normal versions somehow through multiverse shenanigans <3

KP: the only way this version of prime can redeem himself from the creepy underage human girl bullshit is if he gets a good hard dicking from megatron. next

Prime Wars: huge "ex-husbands go on a road trip with their disgruntled daughter" energy here. megatron also LITERALLY says "oh optimus, if only you could see me now" <3

Earthspark: again...need i say why? they're pals and working together from the get-go, what's not to ship??

Skybound: optimus literally wears megatron's arm. truly beautiful <3

The winner takes it all

The loser has to fall

It's simple and it's plain

(w/o effects)

Bonus! (w/o flowers)
