If you were to have a Mega item (other than the Mega Ring), what would it be, how would you use it, and optionally, would you say anything as you're Mega Evolving?

Pic related, for me. It'd be a shoulderpad with the Mega symbol on it, and I'd press it just like the three characters in the gif are. I'd probably say something cheesy or weeb-y, like...
> "<Pokemon>, heed my call! Surpass your limits and we will conquer!"
or something.
