The Warriors in Enemy Quest are this, being both incredibly strong and surprisingly swift and agile. Their durability is nothing to sneeze at either, as "During the war, they put on brass armor and charged through hails of bullets."
The Brute in Ninja Spirit is revealed to be like this when he dodges a lightning bolt.
The titular doctor/ninja himself starts out as a low-level version of this, capable of moving at insane speeds and surviving a large number of gunshot wounds (if only barely), but not being particularly strong compared to other characters in the series. This apparently changes by the second-to-last arc, where he takes out the aforementioned Mongo with a single punch while barely even paying attention.
Specifically, Schlock looks slow because his resting form is a rough, grey-green pile that looks like waste products, but with the exception of his eyeballs, Schlock's entire body is made of Grey Goo that can function as muscle tissue and sniffs out other fragments of itself to recombine if he's torn apart. He "runs" by flexing his entire body to bound over the landscape. And then he figured out how to use his iconic plasma cannon as a plasma rocket.
Airman Higgs mixes this with Made of Iron. He's shown himself capable of moving fast enough to practically Flash Step from normal perspective, is capable of smashing through Clanks with a single strike, and was capable of outpacing Zola even when she's nigh on overdosing on Psycho Serum.
Gilgamesh also qualifies when he gets serious. as does Tarvek. And Zeetha. And Othar. And Doctor Sun...
The Dreadful: Jeanne Noelle is fast enough to dodge bullets, and a punch from her can lift a person off the ground straight up. Said punch was delivered to someone with their gun to the back of her head.
The Fox Sister: The Kumiho is incredibly quick on her feet but also is able to both take and dish out.
