“Bull SMASH!”
“What my compatriot means is, we would enjoy discussing how you’ve come to be hear at this very place we have been commissioned to destroy, but as we are in the middle of said commission, we must defer this conversation until–”
“Bull SMAAAAAAAAAASH!”
“…Ahem. Unfortunately said deferment will have to be of a physical nature since our patron did insist that no one survive–”
“Bull going to break you in half!”
“–I’m afraid that my colleague is correct in this assertion. Have at you! Huzzah!”
No one knows where Troy and Bull come from. No one know how one being can be at turns fiendishly clever and dull-witted at the same time. The divergent personalities of Troy and Bull hold many confusions and contradictions. for those who meet them. What remains simple is that destruction and mayhem grow from the seeds they plant; between Troy’s incredible mastery of alchemy (used to created explosives mostly) and Bull’s supreme ferocity and strength, the Smashing Brothers can tear down any structure that can be built. Siege breakers without equal, they can be found in battlefields around the world.
“Two Heads Are Better Than One!” Opening
Bull: We Smash you and you and you….we smash just about everything!
Troy: “Indeed! Now we sow the seeds for your destruction. Watch as we prepare our ultimate strategem!”
Bull: “AARRGHH!”
Troy: “Huzzah!”
Bull slams his club into the ground, cracking the earth open while Troy throws miniature firebombs into the cracks. Whatever they are doing, it doesn’t look pleasant.
As a free action during the opening of the worldbreaker poewr, each player can choose to take on of the following actions:
Spoil the Strategem (DC 23): Ettins aren’t really that clever. You easily keep from being hampered by their “ultimate strategem”. Skills: Thievery, Perception, Nature. Success: You can ignore the effects of the zones created with the worldbreaker power for its duration.
Read the Attack (DC 23): That is a big club. You wouldn’t want to be hit by it, so you watch it carefully. Skills: Insight, Perception, Athletics. Success: You gain +2 defenses against all attacks from Troy and Bull.
Big Oafs (DC 23): One is smart, the other is strong. They are both incredibly slow. You exploit this fact and stay one step ahead. Skills: Stealth, Bluff, Acrobatics. Success: If Troy or Bull miss you with an attack, you gain combat advantage against them until the end of your next turn.

I rather like the concept (and, indeed, I made something quite similar just a few days ago, but it used two separate tokens, and two almost complete sets of actions.) What you might look at, though is this HTML monster block creator. It requires just a bit of tweaking, if you want it to look like the new statblock setup, but it should be a nice alternative to what you’re using now, and requires little to no code to fix up. http://omnichron.net/external/op/tools/mon.html
