My latest vector work is well-made rendition of the beveled 3D-looking Mega Man Star Force emblem.
It looks very close to the original, plus this one should be mathematically accurate. You won't find this emblem anywhere else on the Internet, let alone with a transparent background. The size is okay for almost anything needed. But in case you need a larger size or want to see the SVG file for yourself, I've made it available.
You must save it to your computer for it to work. I use Inkscape for vector.
