Talk:Ultraman X (character)/@comment-25451319-20160101223430

You know, I just realized something. If Greeza was the source of Dark Thunder Energy, why didn't X pick up on the fact that he was still alive after the fight against Tsurugi Demaaga?

I can only think of two possible explanations.

1. There are other things that can also create Dark Thunder Energy. This seems extremely unlikely to me, however.

2. He never saw Greeza use Dark Thunder Energy before. This option would be more plausible, especially if their first encounter was the chase that led to the Ultra Flare incident.
