Do they have a lifespan or they are immortal???

Is it possible for this message to get straight to the staff of DC Comics?

I would like to see Mr. Terrific invent a chip or a device that would protect humans like batman, green arrow, or metahumans or everyone from the dcu from gunshots or physical attacks on their open areas of the body especially in the mouth area.. where batman's most vulnerable part is located. Also, nightwing's head and the robins.. something like an invisible, localized force shield (maybe a byproduct from the nth metal or prometheum metal) that would protect them from larger impacts such as being hit by stronger forces or gunshots.. cause i think hitting nightwing or robin's head against a wall by darkseid would cause u instant death maybe a little impact for the damage but guaranteed there is a stronger protection for them and not just because they are superheroes that's why they are invincible.

i just want to make our dcu step up more to the game by making our characters wiser and stronger. Especially Mr. Terrific since he is the smartest man in the DCU. More power to this page!

Does anyone wish that the Watchmen movie characters crossover in the DCEU, if they do an adaptation of the new DC Rebirth comic Doomsday Clock coming this November?

If only, if only.

I ask this because Shabook on MavelCinematicUniverse.Wikia.com did something weird and I want to know whether me posting a theory like the following regarding the DCCU/DCEU would be removed or not.

If you see my latest comment on the Real Mandarin page on Marvel-Movies Wikia you'll see something I posted on the Questions And Answers Forum which has a bunch of theories about different MCU things of course. Shabook deleted mine. Shabook told me he deleted it because it's about a theory and speculation. Everyone else's post on that Forum is staying. I asked Shabook why Shabook did that on Shabook's Message Wall and Shabook blatantly refused to give me details on why my theory and speculation should be deleted while everyone else's stays while disliking that I complained about Shabook's deleting it.

I then posted my Mandarin question/speculation in General Discussions which is currently chalk full of theories and speculation. Shabook immediately removed it "because of Spam" and stopped me from posting on that website until 3/3/2018!!!!!! ... What about what Shabook did makes any sense?  Thoughts?

Can the page about Invulnerability be locked, ImperiaxSeed constantly edits it to maintain incorrect facts.

Does anyone know what Wayne Corp logo looks like pre-1980 before they started to use the "Big W" ?

Why lately are writers making Kryptonians weak, like a bunch of Styrofoam men. SV captured the scope of Kryptonian power really well.

i was doing some research about the DCEU and i saw on a few websites that the films Lobo, Dark Universe/Dark Justice and Blue Beetle/Boostergold are all in the DCEU is this true?

I seem to recall that they said this version of Lex was a self-made billionaire by age 18. Then I see the movie and he says he just took over from his dad? Did I miss something?

Hey, just wanna confrim... does this look like it's the painting in Lex's house? You know, the one with the angels and demons that foreshadows the JL villain? 

(I didn't upload it because I wasn't sure I'd be allowed to or not). 

Thanks in Advance!
