Random headcanons that nobody asked for
The criss-crossing scars on Yondu’s head are Kree slave marks, and anyone who knows anything about anything knows this. Most former Kree slaves would cover the marks, with wigs or hoods or more scars, since escaped slaves are to be killed on sight by any Kree that crosses their path (the only “freedom” granted to slaves by the Kree is death).
But not Yondu.
He keeps them visible, to remind everyone around him where he came from. What he has endured, survived, and escaped. Ain’t nobody fucking with a former battle slave who ain’t afraid to face those who thought they were his masters.
Also, he didn’t have the Yaka arrow and the fin prosthetic when he first picked up Peter. He used a Kree battle hammer, stolen from his old tormentors. It was a brutal weapon, crushing bones and splattering blood all over the place, and after the first time Peter saw Yondu in action he spent almost three weeks hiding, utterly terrified of this brutal blue warlord he’d gotten stuck with.
Yondu never said that he acquired the Yaka arrow for Peter’s sake. He claimed he got it just because it was a faster, less messy way of killing people, and that he wanted to be more Centaurian, less Kree.
And if Peter thought the arrow was cool, and far less scary than the blood-stained hammer, well, that was just ‘cause Terrans were too soft to handle a bit of gore and nothing that Yondu had even considered when he decided to ditch the hammer, no siree.
