Hughes takes charge of his first game at St Mirren Park as Caley Thistle look to extend a five-match winning streak and consolidate second place in the Scottish Premiership.
The former Falkirk and Hibernian boss was at training for the first time on Thursday and Warren is determined to give him three points in his first match.
The centre-back told CaleyJagsTV: "You can see from the moment he walked in and met us on Tuesday that he has got passion, drive and energy, which he has brought to us.
"I think it's good for him to come in and see the group of players we are.
"It seems he's a hungry man who wants success, which is good for us.
"We were at training and he has a laugh with us but you can see there's a side, if you are not pulling your weight, you will feel the full force of him.
"It's up to us to get him off to a winning start."
And he will take a step back in Paisley to allow the players to show him what they can do.
Hughes said: "I will sit in the stand because I just want the boys to go out and express themselves. "There is no pressure on them because there is a new manager. I want them to go and be a free spirit."
The players have shown they are self-motivated in recent weeks having won three games since Butcher told them he was heading to Easter Road.
Warren said: "When you get a situation like this, it's a test of character of the players you have got in the dressing room.
"There are some good boys in there who like to pull each other through.
"We have got some good results and carried on where we left off."
And they proved they have their own standards to maintain by issuing a punishment to their new boss.
"He has been fined for his dodgy suit and a dodgy belt," Warren said. "It's part and parcel of coming into a new changing room - you have got to be smartly dressed. He got a tenner fine."
