Alex Cane

Alex Cane was an arms dealer affiliated with The Penguin. He was also a murder victim.

Batman: Arkham Asylum
Alex Cane was one of the Penguin's thugs, acting as an arms dealer between the Penguin and associates. He has had a list of prior crimes, including assault and carrying concealed weapons.

On Christmas, Alex Cane, alongside another member of Penguin's gang, a martial artist and top hitman named Qing Lu were waiting for what was presumably an arms deal to occur at Coventry. Unfortunately, Cane ended up betrayed and shot through the heart by Lu, who wanted to advance up the ranks quickly. Cane in return used a Molotov cocktail in an attempt to ensure Lu died with him, but Lu escaped by jumping up a wall and up a ladder, leaving his DNA behind. Batman, having learned of the fire at Coventry as well as the murder, deduced what had happened, although he initially guessed Penguin hired Lu to take Cane out. He eventually tracked Lu down to Penguin's Hideout at Amusement Mile, and proceeded to knock Lu and most of Penguin's men out.
