Havok has had his share of terrible costumes. Pretty much anything past 1994 or so. I’m pretty sure you can add this one to the list. For me, you can’t get past the perfection of his original outfit. It’s great and if you don’t think so, there’s the cliff off which you can dive.
I’d also like to point out that TRON ruined comics forever.
That said, I tried to keep this simple and slightly reminiscent of his original look with something to call back to the headgear (which again, is great) without doing the headgear.
