Miguel O'hara also nicknamed 'Ghost' is your companion to defeat the enemy.

He is very cold and serious in battles, you hated this thing about him because he never let you talk, he only listened to the communications they gave you.

maybe he hated you maybe not, you didn't know for sure but missions are life for him.

when you called him ‘miguel’ he got even angrier but you liked to tease him, he liked it better if people called him 'ghost'
