@NewSun; Aaron Looks good! Only a couple things...

1. I understand as an Android he is capable to punch with extreme force but I am thinking that 3,000 pounds of force is a bit much. I did a little research and saw that a professional super heavyweight boxer had only been able to reach 1,066 pounds of force so I think it would be fair to drop it down to 2,000 would be more than adequate :)

2. I appreciate you wanting to give your character good weaknesses but I think a bi-annual core replacement is a bit extreme lol The power cores are quite powerful and very good with maintaining their sustainable power source. I think 3-5 years would be more accurate. Though if you wish to keep the bi-annual replacement that is fine :) Just my two cents on the matter lol

So only change the punching power a bit and everything should be fine :D
