You've only spent 19 of your 23 free Ability dots, you can have another 4 more dots, but none of them can be higher than 3 dots
(3 NP Spent for 9 additional Attribute points) You get 24 free Atribute dots. I see 12 additional Attribute dots above, which means you need to spend 4np.
(4 NP Spent for 24 Ability Dots) You only need to spend 1np for the 6 extra Ability dots you've added
Backgrounds You get 7 free dots on these
Mentor 5 5bp free
Attunement 1 1bp free
Eufiber 1 1bp free
Node 4 8bp This only costs 4bp
Up to here, you've spent 7bp so far, leaving you 15bp. I assume you spend another 14bp on 2 dots of Quantum. At this point your Quantum is 3, Willpower is 1.
Quantum 1np (5) I assume you mean you're buying 1 Quantum for 5np?
Bulging Muscles 2(Arms and legs are unnaturally beefy for his frame. His skeletal muscles are toned and lithe in spite of this he looks like he's trained at the pinnacle of fighting though he can't be more than 13.)
Glow 1(His Tail and Pupils Glow with Golden Light, they are very hot to the touch)
Hardened Skin 2(Its dense like metal, his bones are too)
Vestigial Tail 2(Its brindle striped and wrapped around his waist like a belt, doesn't look like it moves)
Permanent Power 1(Quantum Bolt which he keeps charging in his vestigial tail.)
Armor 3(6np)
Flight 2(2np+1 taint)
Quantum Bolt 4(8np) this costs 12np
MEGA ATTRIBUTES
Mega-Strength 2(3np+1 Taint)
Mega-Stamina 2(3np+1 Taint)
Mega-Dexterity 2(3np+1 Taint)
Mega-Perception 1(2np +1 Taint)
Up to this point, it looks like you have spent 40np on Powers, Megas, Attributes, Abilities and Quantum which is too much. Still gotta redistribute a bit more.
Background-wise, I've enjoy much of the detail that you've provided. Two big issues I cannot yet rationalise though. If T is a high aberration, high taint individual, it is unlikely he has such a good relationship with his environment and the people around him as described. (Remember the game mechanics impose negative social modifiers). Or put some dots into Allies or Contacts. Also if you're going to say he's got some money or a business going, then I'll need some dots in Resources. The second is a hard no on the permanent power aberration on Quantum Bolt, that's akin to Johnny Storm having his fire permanently on, burning everything in his path. A permanent Q Bolt seems to me like a constant death ray killing and damaging everyone around him. (Which I do like a lot as an idea, but seems unplayable as a character), as opposed to a permanent power like the Thing.
