Hmm, note too keen about some of his ideas.
1. The fins on the gloves should not be fabric, but pointed and sharp. The blade should be hidden and pop out with a muscle twitch.
Pointed and sharp yes, pop out...no.
2. Batman's Belt. The old capsules ceased being effective 25 years ago. No, they never were effective, nor is a World War 2 garrison belt. But a utility belt, as in a carpenter's utility belt that holds weapons, grapplers, guns and crime-fighting paraphernalia as a uniquely designed true utility belt would be perfect.
Maybe but I prefer the look of the "garrison" belt.
3. Boots are thick soled ninja boots with wraparound flaps velcroed up his leg. In the shank, weapons.
Please no.
4. Costume. Bulletproof and watertight, thermal coils and refrigerant coils throughout, acid resistant, padded at the shoulders and riddle with structural supports for (if needed) a kind of super strength.
That's already the case.
5. Cowl is pulled over a face plate containing radio, infrared biometrics and night vision as well as video feed. A waterproof breathing mask slides and seals over the face for breathing underwater. (Oxygen in utility belt.)
Great idea.
6. Bat symbol subtle but bold. Dark against dark.
Great but not as he draws it on the pic.
7. Cape stiffens for flight. Acts as fins underwater.
Not seeing this...
