Did you catch this in Transformers: Rise of the beasts Trailer ? #edformers #transformers

[Fearduck]

He's not trying to hide, he probably activated the mask to appear menacing, probably optimus in this movie doesn't know the humans yet, and wants them to stay away from the autobots.

[afonsopiresdelima]

"Now that I have my mask on, he will never suspect that I'm actually Peter Cullen"

[Vaquerochinaco]

Maybe not to hide his identity maybe more like he's ready to fight

[Dycoth]

He's most likely activating it as a way to intimidate the adversary and be prepared in case of a battle

[furionmax]

It's a face guard. Everyone knows that. Optimus only puts it on when he's going into a fight

[Yuhyeauhuhsurebuddy]

I mean, Bumblebee did fight humans who were tricked into thinking he was a bad guy, so Optimus isn't too keen on being friendly to them just yet

[jaydraws]

It's a defense mechanism. People seeing his full emotions is risky am makes him vulnerable. Mask off, he's a kind leader. Mask on, he's a steel cold war machine.

[Anthony]

Someone said it and I agree, its probably just to appear more menacing after what bee went through, probably knows what humans are capable of

[stuffland]

Hiding their identity for what? It’s not like they know him 😂

[LiIRanger]

Because him having a mask definitely hides who he is

[AlayitnesUchiha-hmvg]

Optimus knows the boy had coronavirus.

[animechannel]

Optimus mask activates when he's going to attack, its not to protect his identity

[Hellcatte]

He's not hiding his identity, He's trying to protect his health from humans

[christiandominicbuno]

Optimus Prime: *oh sh*t a human! Lemme wear my facemask. I don't want to get covid*

[dragonhunter]

He most likely activated it in case he was about to fight

[EMRYTATEllll]

Well it’s to protect his face from being shot or attacked

[kadenbass-]

Megatron:”Who is this masked figure i’ve never seen before?”

[johnconor]

Using his mask for hiding his identity? Bro, his mask was iconic to him.

[Tmack]

"We got reports of a 25 foot tall red and blue robot at the scene"

Optimus Prime - "That wasn't me. You can't even make out the face from the video footage"

[zriehasan]

That is not hide id, that is war mode
