And Dragons skipper Willis, signed from New Zealand side Waikato Chiefs, reckons the match-up with the Scarlets is an ideal test.
Willis said: "The quick turn around hasn't allowed the players to dwell on the performance against Glasgow.
"I'm confident that the Dragons will learn from its mistakes, improve its performance and bounce back in a typical local derby."
Dragons coach Paul Turner added: "The Scarlets are a strong side that will give us a tough challenge. They have started their season well and we are fully aware of their capabilities away from home.
"The local derby is always a huge fixture and a great rugby occasion for both teams and supporters. We need a big performance."
Turner's only change is enforced with Phil Dollman starting at full back after Ashley Smith was ruled out with a leg injury.
Scarlets boss Nigel Davies makes three changes for the trip to Gwent.
Wales flanker Dafydd Jones replaces skipper Simon Easterby who starts on the bench, Dafydd James comes in on the wing for flu victim Mark Jones and Vernon Cooper takes Simon Maling's spot at lock.
Vice-captain Stephen Jones will lead the side in Easterby's absence.
