@reemas: Yeah... No. Capital N. I'm running the risk of countering your valid opinion in a very disrespectful manner, so instead I will say I disagree with your interpretation. However, it is YOUR interpretation of a character and its circumstances, which makes it as valid as my own opposite interpreation of the same.
No prep time; no previous knowledge of each other; all canon feats are allowed.
Which "family" wins this bout? Do cooler heads prevail? What would be the Sampsons' reaction to the mainstream Marvel Earth, ca. pre-Civil War? What would be the FF's reaction to the Union's founding family?
Omni-Man. There's an actual reason for his madness/evilness. And he has a true character evolution arc.
As opposed to Thanos's operetta style, mustache-twirling, mommy and daddy-issues-driven, idiotic "plan" for "saving" the universe.
Seriously, the big purple doofus's plan was using an instrument of omnipotence to halve the universe's population, so as to extend the universe's resources. He must have ridden in the short bus to not have realized he could just as well triple, quadruple, or multiply to infinity the natural resources across the universe without killing anyone; since he was omnipotent and such. What an f****ng idiot.
In an attempt to remove Superman and his cohorts as an obstacle to his aspirations to power over all, Mordru the Merciless casts a spell to expel Kal-El, and all those realted to him, from their universe/dimension, and cast them out to the furthest, most antitethical location possible, whilst setting up the most comprehensive barrier he is able to in order to prevent their possible (eventual?) return.
And thus are Superman, his family, and those most closely associated with him, castaway on Eath-616 of the Marvel Universe shortly before the tragedy at Stamford, the Superhuman Registration Act, and the subsequent "Civil War".
An ROB plucks you out of your own time and throws you backwards into the time stream after changing you on an atomic level, granting you the abilities, knowledge, and metahuman powers of one of six individuals.
Throw a d8 to see which character will you be ROBd into:
2. Omni Man
4. Allen, the Alien
5. Mr. Majestic
6. The Utopian
Throw a d4 to see which time period/year and location you will be translocated to:
1. London, 1556 - Mary I Stuart is Queen
2. London, 1835 - William IV is King
3. London, 1933 - King Edward VIII sits on the throne of the British Empire
