Panzer Dragoon Zwei Question

Hi, I’m new here. Just had a quick question. I beat Panzer Dragoon Zwei the other day and I only fought one form of the last boss. I was the SoloWing but I lost one life against the Guardian Dragon first form. Then on my second try I beat him… but I did not get to fight a second form. So I started a new game and though I’m not a SoloWing I was able to get the second form. None of the faqs I have read say anything about skipping the second form if you are the SoloWing… Was there a weird glitch or something?

I have not heard of this but it has been a long time since I have played.

Did you still see the ending and credits?

Yeah, I saw the ending, credits and it graded me.
