Introduce the power gradually to other players. Don’t flaunt it at every opportunity.
When in events allow weaker character puzzle around before you ‘solve’ the problem at hand.
Ultimately, it can be that being around a powerful character, no matter how lore abiding they are can get boring because they just solve all issues with a flick of their wrists.
Same goes for rich character who just give poor characters stuff really easily. Doing that takes away from their own character.
