WHO AM I ? ? ?

As big as a giant, powerful and clever in mind;

Not liked by many, I was hard to find;

Evolving small in size, lickety-split I emerge;

Befriended overtime, having me is the urge.

Transforming life, I am earth-shattering;

Never tired, no qualms when catering;

The more I am told, the more I do things;

I sing and speak, and needs no bathing;

No legs no arms, and not any feelings.

This riddle is diddle; reading it is half the battle;

B@loopuu was the first to figure out; leave a comment on your way out.
