Pound for Pound toughest fish?

Mangrove Jack, the smartest, meanest fish I've ever seen.
 
Has anyone mentioned frog fish? Pound per pound wouldn't a frog fish just swallow anything whole that came near it even if it's opponent were about the same size? Angler fish is another. They are slow moving though (except when they lunge at food).
 
hands down, the dorado, mine (10-12 inches) killed the following all similar sized, african snakehead, black bass, and a large redline, these fish all provoked the dorado, when i sold this beast at 16 inches he continued his killing spree, killing a large black pirahna, about 9 inches, all was peaceful until the dorados tail was bit, these fish are well known for their revenge tactics.
 
I put a 14in. rtc x blochi hybrid in with a 13in. marble cat. The outcome was not pretty. The hybrid started attacking the marble cat as soon as I put it in the tank. It continually bit(full suction force), and rammed the marble cat into the bottom of the tank until dead. After the cat died he continued his attack until the fish was removed. I also tried putting a 11" walleye in with it today with the same outcome. Maybe hybrids are just more aggressive. Ps are overrated, I fed 3 at one time to my rtc I had a few years back. Funny cause my friend lost a bet, some dough, and 3 Ps to my catfish. (I do not condone pitting fish against each other, but there was money on the line ;) but yeah, the hybrid kicks ever fish' *** that I put in of similar size save for the 3 gold fish that live with him now. They are all 6in and smaller. Go figure.
