Go back to the tailor and make sure you specifically check the power 'Throw Spines' to have metal spikes
Because it's the tier 9 power, it's off the bottom of the screen when you are coloring your powers -- you have to grab the scroll bar and drag down to see it. For that reason, the Tier 9s sometimes get missed during customization.
I do not recall having this issue on my metal spines character but I will look tonight.

Reporting back -- Throw Spines has the correct (metal spikes) look for me. Check your power customization at the tailor?

What they said. 
No problems here. Sounds like you just forgot to change them.

I had changed my spines to metal spikes at the costume shop.
I noticed that only Throw Spines is bugged. When I activate Throw Spines my metal spikes turn into the default spines for both the spines I throw and the spines protruding from my toons body. When I activate the next power they all revert to the metal spines.
I'm not certain where else to post this so I figured the scrapper's forum is a good place.
