what you need to accomplish:

1. Defeat Ultraman with 50% or more health remaining with Dada (Ultraman can be weakened by previously captured monsters).

2. Defeat Ultraman before time goes below 1:30 as Dada

3. Capture the Super Beast Vakishim and have him fight Ultraman

4. Make Dada change to his A and B type faces during the fight against Ultraman.
