FWIW, I think it makes more sense to play Silver/Bronze Age Superman as a GM's ''deus ex machina" within the Champions framework, rather than as a guy with a character sheet. The mechanics of the game tend to fall apart with the extremely powerful DC folks (e.g. a maximum of 12 SPD).
How I chose to represent Superman's superspeed is detailed in the "About the Conversion" section, and IMHO, I think it is both more playable and more importantly, more accurate, than if he was given 50 SPD or something.
Limiting him to 90 active points per power helps establish parity with "typical" 250-500 point Champions folks to the point that he might be playable. But that limit just scratches the surface of what pre-Crisis Supes is capable of. 90 active points doesn't get you to igniting distant suns with heat vision.
Even an EB by itself can't give you that sort of effect. Igniting distant suns would be a fairly powerful Transform instead of just an EB by itself (there's not a point where the book says, "Okay, if an attack does this much BODY, it can ignite a sun too"). The key to representing Superman that this sheet takes is that just buying things in gigantic bulk doesn't accurately represent Superman; this is why other character sheets I've seen of him are both unplayable and rather sloppy; he has a wide breadth of ability that isn't shown.
To represent his limitless strength, for instance, I bought extra STR past the 90 Active Points with the Does No Damage and No Figured Characteristics enhancements.
That being said, it's a fine effort if you want to make it. You're missing the power stunt where he freezes someone into suspended animation, which goes a little beyond an Entangle.
Ooooh! Forgot about that one. Thank you for bringing it to my attention, UncleMxy.
2) Self-hypnosis. Pre-Crisis Superman could hypnotize himself very powerfully, to forget certain events typically, and otherwise force his mind and body to do unnatural things when the plot device called for it.
I bought him Simulate Death and other Talents that partially represent this. Here are some ways to handle this sort of thing:
1) Shape Change with the Mental Group;
2) Allowing Superman's Super-Hypnotism Transform to work on himself. Normally, this isn't allowed, but may be justified as a part of the "special effect" that the hypnosis comes from his eyes. Yes, it can be blocked or deflected by mirrors, but he can use a mirror to hypnotize himself. Also as a disadvantage to the special effect, he can be hypnotized into hypnotizing himself (don't think about it too hard, your brain will pop like a grape).
You know, considering the vast range of Classic Superman's powers, I'd think that a Variable Power Pool would almost certainly work for him..
Others may feel differently, but I've always thought that in a representation of a fictional character, that something like an Omni-Power or a VPP is kind of a cheat; that is, instead of going to the trouble of figuring out what the character can do and has done in the past, it says, "okay, here's a bunch of points, now leave me the hell alone."
