Let's see if this works. I've never tried to copy text from the Monster Builder to the net before.

Tactics:Leo has four phases. During phase one, Leo is in control of the demon inside him. He remains in control of his demon until he takes 97 hps worth of damage, at which point the demon takes over and Leo grows to large size. He remains in demon form until he takes another 97 hps worth of damage which allows Leo to regain control of the demon. He remains in that form until he takes another 97 points of damage, at which point the enraged demon emerges from Leo's body, resulting in Leo and his demon both being active at the same time. The demon and Leo share the same hit point pool, both die once they reach 0 hit points, and both take their turn on the same initiative number.
Also, I made this creature before MMIII so the stat block hasn't been reworked into the prettier format. I had a huge tactics section instead.
The encounter started with Leo's cult trying to draw the Demon from Leo's body on a dias (4 minions standing around him, the other 3 level appropriate creatures looking on). The PCs were sent to save Leo, as he was a famous demon slayer, so weren't expecting him to attack, but the demon had corrupted him and Leo was driven insane.
