Looking at the Martian Manhunter now, what I find myself wondering (apart from why the green skin) is why Mars? Apart from alliteration, I mean.
No doubt its nearness played a part, although these days that works against him, as we know a great deal more about Mars now. The idea of human-like life on Mars has gone by the wayside. and if you asked anyone these days about Martians, they would probably think of Marvin the Martian instead.
I know I’m not the first person to comment on this, but I’m really pleased with the new Aquaman. Anyone who watched the old Super Friends show no doubt wonders what the point of our finny friend is: he can swim, right, and communicate with fish? To anyone who just watched the show, Aquaman must have seemed only marginally more useful than Bouncing Boy. (A true Ronseal hero, the name said it all.) There’s even a song, Aquaman’s Lament, in which the hero bemoans his general uselessness.
