Well, the big thing here is his armour. I can't see Chief taking out most low metas (like Spider-Man) but I can't imagine most high streets taking him down either because of that armour. If he is high street, he's the top of it. mmm
Bane, Batgirl, Batman, Black Panther, Blacklash, Bronze Tiger, Bullseye, Captain America, The Cat, Constantine Drakon, Daredevil, Elektra, Green Arrow, Hawkeye, Hush, Kingpin, Lady Shiva, Ravager, Red Skull, Richard Dragon, Rose Tattoo, Taskmaster, Union Jack, Nightwing, Red Hood
How many of them can consistently win against Chief? Not many. It's in low meta where the consistent losses for Chief come:
