You can go pretty far on 60pts but you may want to simplify a little.
I don know who alpha is, but superman doesn't seem feasible (even one power at a time) on 60.
Variable effect would net you about 3dice a d be a willpower hog. I don't recommend it unless you want to also "turn the bomb into flowers and save the day."
If/then 1 power at time is either awesome or not really a flaw, depends on the player and the GM, so I wouldn't count on it.
A few points of LAR is cheap and easy and allows you to get shot up without dying. I'd go with 4hd so only Big guns and the really lucky do any killing.
Flight and superstrength can be rolled together either as jumping with hyperbody or adding attacks with Mass/hi capacity extras to flight. I'll go with the flight power since its like tactile Telekinesis.
Damage Resistant 2/d 4hd, 16pts
Defends 2, Self, Endless 3, armored defense -2, if/then limited tactile sense -1
Flight 5/d 3d+1wd, 35pts
Attacks 2, Mass, Booster 1, attached to useful-2
Useful 2, Speed, Duration 2, Booster 1, Limited uses -1
Cosmic Beam 1/d 5d+1wd, 8pts
Attacks 2, range, no upward limit 2, if/then not in radio shielded rooms -1, Slow -2
The beam requires a round to charge and anyplace that doesn't get a cell signal doesn't receive the "cosmic rays" he needs either. I'm thinking of it like he's magnifying and refracting the energies toward a target like a kid standing over ants, you can flavor to taste.
He can "lift off" 4 times then needs to spend a round "exposed to cosmic energy" (essentially be near a window or outside). To recharge fully he needs to achieve a sufficient altitude to receive "unfiltered" cosmic power, top of Everest or higher. Usually not a problem if he uses his last charge to get that high.
You could clap an if/then weakness on the armor so xenon lasers cut through it or you could give him an allergy on the archetype ala Kryptonite. He's hardly unkillable so I'd skip it. With xp you can always improve the powers (remember to take the mutable quality on your archetype so you expand into enviro immunity and hyper body).
Good luck!
