Powerful enough to walk through few hundred vibranium missiles and not get a scratch. Powerful enough to own Wakanda all by himself. And most importantly powerful enough to defeat Spider-man.

The same way the Spider Queen is. Spidey constantly deals with such threats.
Morlun's potential wasnt fully shown when he first appeared. He wasnt going all out against Pete. But even then Spider-man only managed to hold his own for some time. He was unable to do any damage to Morlun. In their very first fight Pete compared Morlun to Hulk physically. In his later appearance Morlun was shown ripping though adamantium net like it was made of paper.

His body is made of.. well.. magic. Doubt tp would work. So far he's only been beaten twice. Both times with magic. So Aquaman might have a shot depending on how powerful his hand is. Im no expert on him.

The hand is pretty powerful no doubt, but I don't know if it's enough to put down a guy like this.
One thing it is good at, though, is dealing with magical enemies that are considered "unnatural", so maybe he has a shot there; I just don't know a whole lot about Morlun.
