Trinity

Trinity Mark is a special action present in Kingdom Hearts, not to be confused with the offensive ability Trinity, the effect happens when Sora is near a coloured Mickey Mark, the last command box will change to Trinity. Pressing it will allow Sora, Donald and Goofy to do various commands depending on the colour of the Mickey Emblem, it can either open new paths or obtain rare treasure. Some are even required to complete Jiminy's Journal and progress the story line. A total of 5 coloured emblem can be learnt. It should be noted that Trinity Mark can only be accessed when Donald and Goofy are alongside Sora. Replacing other world characters/allies, will cancel this ability.
