^ It's deliberately that absurd. And I have seen some real edits that were not that far from this example.

Tense has nothing to do with updates. But basically, as a rule of thumb:
 * If the character is history, the whole page should be in past tense (with some small exceptions, like quotes or some of the trivia).
 * If the character is alive, then introductory paragraph, appearance, personality, powers are usually mostly in present tense (except if they describe past characteristics of the character).
 * Plot should usually be all past tense, as this section describes past events.

Think about the character pages as normal biographies, then this is natural.
