Well, yes there is a bit more evidence in that name Apollyon as pointing directly to Satan.
Ex 12:23
23 For the LORD will pass through to smite the Egyptians; and when he seeth the blood upon the lintel, and on the two side posts, the LORD will pass over the door, and will not suffer the destroyer to come in unto your houses to smite you.
KJV
Rev 9:11
11 And they had a king over them, which is the angel of the bottomless pit, whose name in the Hebrew tongue is Abaddon, but in the Greek tongue hath his name Apollyon
KJV
Abaddon is a word from the Hebrew that means a destroying angel.
Apollyon is Greek for 'destroyer'.
The fact that both of those are in capital letters as pronoun names, it is even more emphatic that the Destroyer is directly referring to Satan. Even more with Greek Apollyon, because it comes from a Greek word that means to perish, or perdition, which is yet another pointer to Satan since only he and his angels so far have already been judged and sentenced to perish in the future lake of fire.
