Does Shadow have a super secret power?

He stronger powerful and más faster and his speed is más amazing más than sonic is

Well... he wears limiters on his wrists and ankles... when he removes them... his power level increases, but he gets tired quickly...

Maybe he does but just hasn't found it yet

His power is super shadow.

Which kind of secret power?
All he have are Chaos Based moves,Super Speed,Super Form,Immortality and relation with Chaos Emerald.
Nothing more,nothing less.
