You ever think that maybe Megamind just isn’t cool with Metro Man at all? Like sure he loved being evil and trying to destroy the dude so I GUESS that can be misconstrued as frenemies, especially when Metro Man calls him his “little buddy”.
But Metro Man was the person who sent Megamind into the spiral of “I am the bad boy I can never be good I will never be the good guy.”
Even when it’s very clear that he’s switched sides, Roxanne is very clear that they should team up, and even still, he says, “I’m the BAD guy.”
Like Metro Man fucked up his whole psyche instead of helping Megamind understand this planet he was on after spending his whole childhood in JAIL FOR NO REASON OTHER THAN THAT’S WHERE HIS ESCAPE POD LANDED.
Why would they be friends??????
I have to do something with this.
(( For me it
involves what we don’t see in the movie. Which is a decade of battles and
growing understandings. Summed up very shortly in the flower scene.
“I didn’t mean to destroy you. I mean, I meant
to destroy you, but I didn’t think it would really work. What’s the point of
being bad when there’s no good to try and stop you?”
This plus the yellow roses for friendship and
the “little buddy” by Metro Man, paints a much deeper picture than just
what the movie shows of their relationship.
Megamind didn’t want to kill Metro Man, not
really. There was the joy of victory and success, but the horror on his face
from the skeleton says that even at the start its more complicated than
simply “yay i killed him.”
But his perception of right and wrong and good
and bad is horribly skewed from his upbringing and the difficulties he went
through growing up. This effects his decisions horribly throughout the
movie.
Also, last case point of Megamind cares for
Metro Man (whether he should or not) I present this face:

of Megamind looking at Metro Man. Boy CLEARLY
has feelings that aren’t ‘i hate you” and of the two of them, Roxanne is
the one that’s angry at Metro Man.
I wish HORRIBLY that
the movie had done more with Metro Man’s character or DO A FUCKING SEQUELL!!!
so we could get more canon development for the character, but alas. ))
