Ok.. I was thinking.. about armored core and sergals.. so i put them together...

Status
Ac name:....
{Ap}: 40,000
{Ce def}: 2000
{Te def}: 2000
{Ke def}: 3000
{Leg}: light Reverse joint
{Weapons}: physical attack such as fist and tail whip. (Also uses energy blasts from energy guns not equiped to him right now though..)
{More status}: He has a quick lock on and can dish out heavy damage and still move incredibly fast. His defense is solid and it would take about 4 ac's to kill him. As he fights an ac he scans them and learns there attack patterns and stores the data in his tail, If you were to cut it off some how...
