Larry "Pixy" Foulke
Character from the Ace Combat series , Only appearance in Ace Combat Zero, he begins as our companion, our equal, a friend or brother, but as we approach the end, he distances himself from the protagonist. Ending up fighting him in the last mission under. Even when he is against us, he continues to speak to us as he always did. Casually droping quotes That hit hard like "<<You and I are opposite sides of the same coin...>>" , "<<When we face each other, we can finally see our true selves.
There may be a resemblance, but we never face the same direction.>>" His 'betrayal' being one of the saddest (in my opinion)
I'll let you find the plot and read for yourself by watching the Ace Combat Zero missions for yourself
