11. At the end of Stage 25, you are due for a surprise. Even if you already have (or missed) the two capsules needed for a Dimension warp, the last opponent will drop one more which has a strange glow. What is the function of this capsule if caught?

Answer:
Your ship will immediately become a triple if it is not already.
The tripling capsule is probably the nicest thing available in the game as it essentially provides you with one or even two extra lives when you have been hit in the previous three, extremely hard, stages. It is thus usually advisable to not risk a ship capture in stage 23 to 25 even if you do still have spares available (freeing yourself again without losing lives is quite hard in these stages). Just do not let that last opponent escape and make sure it would not drop a normal warp capsule (the normal one overrides the special one).
Special geek info: With these possible two extra lives, the two you can get off the similar hidden stage 15 bonus and the maximum of four points-based ones, you can get 8 extra lives in the game. Add in that, at the most customer-friendly settings, you get 5 lives to start with, and the maximum number of times you can die in one game is 13.
