Bostro looks tough with a white pin-stripe suit, red top hat and red shirt. He also resembles a warthog.
Bostro gives to puzzles in the game Professor Layton and the Unwound Future.
He is Dimitri Allen's henchmen and was very disappointed when his real leader was in fact Clive. He commands other members of The Family to Get Lost whenever they need to change places. Luke Triton's Parrot Friend mimics Bostro's voice to let the group continue in their investigation. Bostro sets The Family onto the group when it has became clear that they were in the Casino.
Bostro gives the player three quests, these are Family Business, Bad Luck Bostro and Family Nutritionist. He is always found in the Golden Spires Casino, which he seems to own, similar to the Gilded 7 Casino in Professor Layton and the Unwound Future.
"As Dimitri's henchman, Bostro has never doubted that his boss is the true head of the Family and is loyal to a fault. This blind devotion has made him a useful tool to Clive, but he remains blissfully ignorant."
- Bostro's name may come from a mixture of the word "Boss" and the italian word "mostro", which means "monster".
