What would be a good hairstyle to use?

Spikey is the only one I can think of that comes close...

Does anyone think messy is a good one?

Mm... it's a bit too tame for him, I think. I'd use either the one suggested, since it at least goes back in a similar manner, or the Flame hairstyle, for the sticky-uppy properties and the appropriateness. (I might use the Smirk mouth, too -- Axel is pure attitude, man -- but it's up to you.)

I would try layering red spikey hairstyle over Lililace AllClassedUp wig....layering looks a little off..but it's the best I found for his hair at least.
