The staff could bring out a new side of his leadership. If it gives him an edge in battles or in solving magical problems, his friends would look up to him more. This could lead to him evolving into a more decisive leader. He would have to make tough calls on when and how to use the staff, and this would shape his character in terms of decision - making and strategic thinking.
The staff could make him more confident. If it has powerful magic, he would feel more capable of taking on difficult tasks. So, his character might shift from being a bit hesitant to more assertive.

Maybe he finds it in a hidden chamber at Hogwarts. There could be some ancient magic protecting it, but Harry, with his knack for getting into trouble and finding things, stumbles upon it.
He could use the staff to battle dark forces in a more unique way compared to his normal wand. The staff might have some ancient magic that helps him overcome powerful enemies. For example, it could have the power to nullify certain dark spells or even turn them back on the caster. This would give Harry an edge in his fight against Voldemort or other dark wizards. Also, the staff could be a key to unlocking secrets about his family or the history of Hogwarts that he didn't know before.
The use of a staff could potentially change the range and strength of magic. A staff might be able to channel more raw magic power, so spells like the Patronus could be larger and more powerful. Also, it could affect the type of magic available. Maybe some earth - based magic, like controlling the movement of rocks or growing plants instantly, becomes more accessible with a staff.
A custom staff could also make Harry more responsible. If the staff is very powerful, he would need to be careful not to misuse it. This would lead to him being more cautious and thinking more about the consequences of his actions, which in turn would shape his character in a more mature way.
It could be Dumbledore. Dumbledore is always full of surprises and he might give Harry the staff as a last - resort weapon to fight against Voldemort. He could have been secretly researching the staff and its powers and decided that Harry was the only one who could wield it properly.

Perhaps it's a time - traveling wizard from the future who knows that Harry will need this staff to save the wizarding world at a crucial point.

This creature, having a deep connection to magic and prophecy, presents the staff to Harry as a means of fulfilling a greater purpose in the wizarding world.
