Cell made similar grimaces against Goku, and he wasn't using his full power.I don't see any reason why he wouldn't have been. Dabura's number 1 goal was to draw energy from Gohan, which he said beforehand he would have Boo's meter filled in no time at all. He didn't even make a dent in it against Gohan. I also don't buy the "Dabura enjoys toying with his opponent" argument. Just because his demeanor wasn't 100% focused at the beginning of the fight doesn't mean he was holding back. The sequence where he tried to kill Gohan with the sword actually shows him trying his best and then getting frustrated after Gohan overpowered him. There would be no need for the frustration if he wasn't giving it his all.
Didn't he still believe he could take out all the Saiyans by himself, even after fighting Gohan?Because he still had the upper hand on Gohan in the fight despite Gohan being physically more powerful. Gohan was clearly struggling with stamina and was huffing and puffing while Dabura was calm and collected.
So where was it said?You've bad memory tho
Nowhere I think.So where was it said?
He called him trash!Chapter: 452 (DBZ 258), P3.1-2
Vegeta: “Hmph…Seems Babidi is really panicking, if you, his #1 man are already making your appearance…”
Dabra: “Hmph…Let’s end the pointless blather there and have all of you come at me, at once.”
That's before the fight with Gohan.
Chapter: 459 (DBZ 265), P2.2-3
Badidi: “How about it, Dabra? Just to be sure, do you have confidence that you can defeat that Earthling [Gohan]?”
Dabra: “Naturally. I fought him a little bit before, after all. There’s no doubt that I can take care of trash like that.”
That's after.
I don't see anything about taking on all the Saiyans after fighting Gohan.
