M-11 is a robot. Originally known as the Human Robot, the character was given the name "M-11" in the 2006 to 2007 Agents of Atlas miniseries as an allusion to its first appearance in Menace #11 (May 1954) from Marvel Comics' 1950s predecessor, Atlas Comics. The character's five-page origin story, "I, the Robot", appeared in the science fiction/horror/crime anthology title Menace #11 (May 1954) from Marvel Comics' 1950s predecessor, Atlas Comics. In an alternate reality from mainstream Earth, a scientist's newly created robot is programmed by the scientist's greedy business manager to murder the scientist. The incomplete robot, however, continues through with his directive to "kill the man in the room", and kills the business manager when the man enters. The robot then leaves the house, programmed to "kill the man in the room".
The M-Twins (Nicole and Claudette St. Croix) are superheroine mutants who appear in the X-Men family of books. Created by writer Scott Lobdell and artist Chris Bachalo, she/they (as M) originally was a member of the teenage mutant group Generation X, and have not appeared in the series since Generation X #58. Nicole and Claudette have various telepathic abilities, including reading minds, projecting their thoughts into the minds of others, and defensively masking their minds against telepathic intrusion. They have also used telepathy offensively to limited degrees, such as mind control and memory wipes. The twins (and all their siblings) are somehow able to merge into various combinations with each other, each resulting fusion generally having a distinct personality and unique set of powers. However, the fusions can be undone by considerable trauma, typically a large explosion.
Baby, I think we both know
It's gone wrong, wrong, wrong
And I know you don't think we can carry it on
Baby, I think we both know
It's gone bad, bad, bad
Think of all the good times we had
Driving to your house
'Member when we first met
Dancing on a friday night
Under the moonlight
Talking 'til the night was gone
In the back of my truck with the radio on
Then that old song comes on
Together we're singing
Forever we're singing
When that old song comes on
Together we're singing
Forever we're singing
That old country song
Yeah, yeah, yeah, yeah
Baby, I think we both know
It's alright, alright
But how could I forget what you did that night
Baby, you told me you loved me in Tennessee
Where we were gonna live
But now you've done a few things that I can't forgive
Driving to her house
Tellin' her you love her
Lying on a friday night
Ring in your pocket
Lying to me all along
In the back of your truck with the radio on
Then that old song comes on
Together we're singing
Forever we're singing
I know we went wrong but we belong
Together we're singing
Forever we're singing
That old country song
Yeah, yeah, yeah, yeah
Yeah, yeah, yeah, yeah
Yeah, yeah, yeah, yeah
Then that old song comes on
Together we're singing
Forever we're singing
I know we went wrong but we belong
Together we're singing
Forever we're singing
That old country song
Yeah, yeah, yeah, yeah
Yeah, yeah, yeah, yeah
Yeah, yeah, yeah, yeah
Yeah, yeah, yeah, yeah
