I would like to add 2 more restrictions to my character's power.
1. Every 12 hours hours he spends in a tech will cause him to lose a month's worth of memory, in chronological order from his day of birth ( I'd say about now, he would be missing about the first 5 years of his life, which a normal human would remember extremely well anyways, this also means he will soon start losing memories of more of his childhood). He does not realize this, and consciously doesn't know he is missing anything because it isn't just going missing. It is getting deleted. (There is a way to get them back though, which would be a part of his story.) I would like to note, he won't lose any knowledge or abilities, he will be exactly the same in the present (unless he stays in for so long that the amnesia catches up, in which case I don't know what would happen.)
This restriction does not apply to people he brings with him, in fact when he brings people, it doubles the amnesia process (excluding the clone who isn't too complicated to bring in and only adds an hour)
2. Any time he goes into stasis can cause full amnesia, though unlike above, the memories are vaguely still there. They are recovered in the same way as above (which is being planned out).
None of these really effect him until way latter, so it isn't anything huge at the moment ( or even anything small) I just wanted to pass it by you.
