I had written out a reply far longer than this however it seems it did not copy correctly before I posted and timed out.

It seems general consensus is in favor of nerfing.

I actually reread my post as found out I meant 0.1 milliseconds. Rather than the fuddle conversion. That is, I originally planned out to use 0.1 milliseconds, but then switched to 10 thousands of a second without changing the milli portion.

I'll remove the ability to change into any form, limiting it to a Wolf, a Raven, Mist, and a Red Dragon, but also remove the cap on when can use such power such that he may use them in daylight. The Red dragon is a nod to some legend.

He can travel between 2 lakes, natural or man-made, in/near NY and LA. They count as bodies of water large enough. He needs no plane. Which is also why I question how did Kami even know of Lord Bedivere's presence in the U.S. as he simply traveled via water. Or how did Kami know of Lord Bedivere's connection to Arthurian legend as he became a recluse during those times only resurfacing during the Normans. I assumed some form of intelligence was done, but even still, he does not tend to introduce himself as Sir Bedivere of Camelot, but rather "The Collector."

During daylight hours, his one asset is absent, hence it is then when he is most vulnerable. During night hours, unless he uses his sword, modern technology renders his power useless as lights are everywhere in a city as already pointed out. Hence what utility does this have in modern times? Hence why he is designed to have unmatched speeds during the darkness as in the old days, there were no such lights and he would be a truly powerful force. It is an antiquated power which is befitting of the old knight.

I will make the speed capped at Mach 3.2. However, do note that Bedivere is ridiculously easy to kill during the day. Especially when he is resting in his water bath per his Draculian coffin to maintain his power. All Kami needs to do is to find Camelot (it's somewhere in Wales), find lord Bedivere's resting place, stab him with a silvered stake. Or alternatively, drop high voltage into the water and watch him fry. Or even bring along a priest to pray over and bless the water and suddenly turn it into holy water.

Here are the restraints to magic.

What are the restraints to Technology?

Kami's also got a magical compound running through him to extend his life, and I assume provide nourishment. His suit materials offer him general protection against the elements. I question if pain means anything due to the dose of narcotics he has for his increase reaction times. There is no mention of limit to his mechanized muscles with respect to time, nor energy consumption. His batteries I had mentioned earlier but again that is a grey area. Hence as technology advances, and stretches into the realm of magic, should it too have a limit?
