How to Help Zal in Prince of Persia (Nintendo DS)

There is no character named Zal in any Nintendo DS Prince of Persia game.

You may be confusing:

• Prince of Persia: The Fallen King (DS) — features the Prince and Zal (a spirit companion).
• Prince of Persia (2008) — Elika is the companion (not Zal).
• Other DS titles: The Sands of Time, Warrior Within, Rival Swords — no Zal.

If you mean The Fallen King, Zal is controlled via touchscreen for puzzles/combat—no "corruption" mechanic exists. Clarify the exact game and situation for specific help.
