Is megatron,Optimus Prime, and The Fallen all brothers??

Technicaly, in the secondo movie, it explains that there where seven primes in the beginning that where the leaders of the Transformers. When they went looking for Energon da blowing up suns from distant planets they followed only one rule. not to destroy a planet with life.And then they went to earth.One of the Primes hated humans and wanted to destroy them da putting on the machine they used to blow up suns. They named him The Fallen. (So yeah, The Fallen was a Prime.)

As for Megatron, Optimus and the fallen being brothers... Technicaly, Optimus and the Fallen are related since they're both Primes. for Megatron to get in the mix, they all use Energon to live so they must be related. But in a way I think Optimus uses the term brother openly as "we are both the same regardless".

That's just my opinion.

Megatron and Optimus are half brothers. Optimus is a full prime and Megatron being his half brother is only half prime.

Its clearly stated in the film 2 that Optimus is the last living heir of the first 7 primes

So technically Fallen is Great-Great-....-Uncle of Optimus

And yes Megatron is Optimus' Half Brother

Megatron and Optimuse are brothers and they are desendents to The Fallen because The seven Primes and the Fallen are brothers. Jetfire explains this when he transports everyone to Egypt in the movie.

No, Optimus prime and megatron are, the fallen is way older so he can not be.

*blink blink* OMG, I had no idea about this. That's in a way pretty awesome.

Optimus Prime & The Fallen are brothers... The Fallen was one of the orginal Primes & Optimus is the last Prime... Megatron will ALWAYS be a Decepticon...

Optimus and megatron are brothers,the only reason that megatron is not a prime is because back on cibertron,when optimus and megatron ruled,Optimus was fair,thus making him a prime,and megatron was firm,so he was called lord high protector.so yeah,they are brothers.

After watching Transformers II and paying close attenetion when Sam dies, there are 6 primes standing there talking to Sam. Megatron is not a "Prime". "The Fallen" is one of the original primes which makes 7, and Optimus is a decendant of them.

Not Megatron!

megatron anD Optimus are brothers ("you left me no choice, brother". and various over canon sources
Optimus is a descendent of the fallen, (as stated da the other 6? primes "you have fought for optimus our last descendent")

and the fallen is brothers with the other 6 original primes "th fallen was stronger than his brthers"

so optimus can't be his anscestors brother (like te can't be your mum's sister/brother)

but at the end of RotF
the fallen "die like your brothers"
optimus "they were your brothers too"

so i'm not sure but i think that when The Fallen detto that to Prime he just meant because they(other 6 primes) were Primes and so is Optimus.

just be glad its not as bad as the G1 constructicons origin, huh?

No, the fallen and options prime are brothers but megatron would, if related, be the cosin o the son of the fallen

optimus detto that before megatron was corrupted that he was like a brother and the fallen is like optimus's great great great etc. uncle o something

since all the highest in command at cybertron are primes and only a prime can kill a prime, that should indicate that megatron is a prime.
so they all should be related (but not brothers)since the fallen is way older than optimus and megatron.

No the fallen is one of the original Primes he just betrayed his brothers
As for megatron, he and optimus used to be Friends while he was a gladiator before megatron became a freedom fighter and eventually became mad with power and ......EVIL!!!!!!

The Fallen was originally Megatronus Prime. Megatron named himself after him before he became leader of the Decepticons. Optimus was originally Orion Pax, and was chosen to be the last Prime. They're not actually related. Optimus calls Megatron "brother," because they were close like brothers before the war, but not literally brothers. Realisticly, one of them may have been a decendant of the Fallen, but there are no hints to this.

Yes they are all brothers plus more.

Megatron isn't Optimus' brother, Optimus was once known as Orion Pax, and Megatron was once known as Megatronus (Copied name as The Fallen before having the Prime titolo taken off him), Megatronus was Orion's idol, Orion wanting to learn about the history and future of Cybertron, when Megatronus was going to the high council to say his vision and maybe become a Prime, he saw fit to change his name, to Megatron, he demanded he should become Prime, but the council were moved da Orion's words, this made Megatron angry, and created the decepticons, when Orion went to the cuore of Primus, he got dato the Matrix of leadership, naming him Optimus Prime, so no, Megatron and Optimus are not brothers.

As for The Fallen and Optimus Prime, all Primes are brothers, so if The Fallen was a prime, and Optimus is a prime, they are brothers, just very far apart.
NOTE: There brother meaning and our brother meaning are different.

optimus is a descendant of the fallen as they are both primes, in Transformers lore megatron was part of a rebellion against the cybertron society for the freedom of all transformers, at the time optimus was just a scrivania, reception clerk but he joined the rebellion and became good Friends with megatron. which is why optimus refers to megatron as a brother

Megatron and optimus are like brothers in arms they aren't real brothers they were comrads then megatron turned evil.

Megateon and the fallen aka megatronus are half brothers and there father and teacher is sentinal prime. Megatron had a resentment towards the fallen because he got special attention for being a prime as for optimistic he is decendan of sentinal and also the last prime and there are 13 primes all together and the fallen got the name the fallen after killing solous prime not for hating humans.

Optimus and megatron are 1/2 brothers
The fallen is related to optimus as the fallen was 1 of the original 7 prime brothers and as optimus is a prime he is a descendant making the fallen either a great-great.......grandfather o a great-great......uncle
Hope this helps

so many incorrect risposte in here being parroted.

1) megatron and optimus arent brothers of any variety, only in the sense that they’re both cybertronians that’ve known each other a long time

2) the fallen and optimus ARE brothers as optimus isnt a “descendant” of the primes, he’s the last of them. he was the final prime created who then got jaded w it all and chose to be reborn as a normal cybertronian, orion pax, who then went on to return to being a prime once more.

3) nemesis prime is also not optimus brother, he’s either his clone o future corrupted self depending on the depiction. ill assume the clones the one being conflated to a brother which ig is fair enough, evil twin. but più recently nemesis is just an optimus thats been influenced da unicron
