Need A Word Or Two

[hammerman]

Im looking for a rather flashy word for someone who, if you do something, he has to do something bigger and better.

Also for a word that describes someone who has to be in control all the time....control freak was my suggestion but need something a bit...would meglomaniac suit ?

Thanks

a megalomaniac imagines himself powerful but isn't necessarily; control freak is better though slangy. "Controlling personality" perhaps.

One-upmanship is the right idea but there isn't really a noun from it ("one-upman") to apply to a person. Same for competitiveness.

Someone who has to be better than everyone else according to my partner who is from County Durham is known as a "Blacker Dog" ie if you had a black dog his would be blacker as his would be better.
A control freak would be called a "nic" initials for Not In Charge because a control freak is not in charge of themselves correctly.!!!!
