Help with a few lines needed

So there are a few lines I am having issues understanding in an adult manga.

Here's a snippet:

ソニックにこわいものってないの
Sonic, aren't you a stubborn person?

何言ってんだい！
オレにこわいものなんてある訳ないだろ！
What did you say!?
Why wouldn't I seem to be a scary person!?

あー
こわかった

I tried translating some of it but I am confused by 'も/の' as in I am not sure if the artist is meaning 'person/thing' or 'particles.'
In the page Tails starts talking to Sonic and Sonic refers by using オレ.

On the other hand 'こわい' is used and not sure if stubborn or scary is used especially when Sonic tells Amy her red clothes and panties are 'kowai' thus forcing her clothes off.

Any help on understanding this more?
Thank you

もの in that context refers to 物; thing(s). You need to pay attention to the function of the particle に in the examble sentences.

ソニックに（とって）こわいもの: "something scary for Sonic"
オレに（とって）こわいもの: "scary things for me"

They don't mean "ソニック/オレ is こわいもの."

Oh now I get it! :3

why are you using とって though?

To clarify the meaning. に can have different meanings depending on the context.

ソニックに（対して）こわいものを見せた。
I showed a scary thing to Sonic.

ソニックに（/から）こわいものを見せられた。
I was shown a scary thing by Sonic.
