My 32 katana/regen scrapper does not wear a cape on any of her costumes. It doesn't fit for her. She's an ex-government agent (and there are questions about the ex-) not a costumed crusader.
On the other hand, my energy/energy blaster does wear a cape, and it suits her just fine.
Capes aren't used for a lot of Assault Rifle types, save the ones that have Energy/Electricity as a secondary and are robots/have robot suits, then maybe.
Most Rifle wielding vigilantes won't wear a cape, because they don't look good with Flak Armor or Suits.
Also, I plan not to have any travel powers for a couple of my characters due to it not working out for RP reasons. It's hard to justify a "true natural" to have any of those powers. I'll just use swift and sprint and maybe slot it for some running SO's and it'll work out.
My main doesn't have, nor will ever have a cape. Martial Artists with capes are silly, as the cape would get tangled when spinning around, doing those kicks.
He's a martial artist, but over the top, like in one of those Hong Kong action flicks. He does things that bend the rules of reality (as a magical martial artist) , but doesn't break them. I took super jump as a travel power, and will take super speed in my 40's. Flying or teleport would be too unnatural, hence out of character.
I have 2 completely natural characters. One is an AR/Dev survivalist, and another is an MA/SR government agent type. I've levelled them up to 6 and waiting for the grappling hook power to be introduced, as I heard it was rumoured to.

With superspeed?
First revolving door n' I'm dead.
Wow...
I guess since I never got into the natural, agent-type hero/anti-hero, I never thought about that not fitting the whole cape thing.
My lack of choosing a travel power was sheer ignorance of the power sets. I started by taking Fitness powers for my (now 25) Science tanker...think the silver surfer...all chrome with no eye slits in his helmet. Anyway, byt the time I got to End Recharge (whatever), I was in my 20s and running with souped up Swift and Hurdle.
Ran respec mish over the weekend and redid his powers. Very little external changed. I gave up Energy defense for Superjump and Combat Jumpnig, and went back to get End Recharge.
I recently pulled my capes off of my costumes. They looked cool but they really did not fit with the hero.
Still got aura effects on all 3 costumes 
Has anyone finished the cape mission and elected not to wear a cape? I did because the cape didn't fit with my character. I was wondering if I was the only one.
Also, anyone else not pick a travel power until they hit the 20s? My tanker, at 13, was running around like a dope...until he fell into Faultline. Then, he was screwed. I had no idea...poor planning...that I could switch power sets midstream. I know...dumbarse...
