Lucas Simms

 is the sheriff and mayor of Megaton in 2277.

Background
Simms was born in 2236. He grew up in Megaton and won his position by a unanimous vote of the town's citizens. He is fascinated by the stories of the Wild West and named his son, Harden, after John Wesley Hardin, an Old West outlaw. Simms is also a member of the Regulators.

He often contests the title of Mayor with Colin Moriarty. While Moriarty claims Megaton to be 'his city,' every resident comments on how Simms is the real Mayor. Simms warns the player of talking to Moriarty, saying the same to his son. Likewise, Moriarty despises Simms.

In 2277, Sheriff Simms foiled an ill-conceived raid on Megaton by a band of Raiders headquartered at Springvale Elementary School. During the conflict, Simms shot and killed the Raider Boppo.

Quest: The Power of the Atom
You can choose to disarm the bomb, in which case Simms rewards you, or you can choose to blow up the town for Mr. Burke and Allistair Tenpenny.

You can also choose to report Mr. Burke's intentions to Simms, which leads to a showdown between the two men in Moriarty's Saloon.

Effects of player actions
If Simms is killed there are unique dialogue choices with Manya and Harden Simms.

Notable quotes

appears only in Fallout 3.

Bugs

 * Like all Megaton residents, Simms may disappear or die. Check Recovering missing NPC in Fallout 3 for help.
 * When Simms is killed by Mr. Burke, a floating blood splatter can some times be found walking the same path that Simms once did. It can cause the game to freeze and you will need to restart the console.
 * He will sometimes follow the Lone Wanderer across the Wasteland. The reason for this is that the Lone Wanderer talked to him before he could auto-talk to you as you enter Megaton for the first entrance. Therefore he will follow you till he can initiate conversation with you.

Behind the scenes

 * Simms' welcoming speech mirrors Marcus' first speech to the Chosen One in Fallout 2.
 * Simms: I'll be damned, you're from that vault, Vault 101. *chuckles* I ain't seen one of those jumpsuits in a long time.
 * Marcus: Well, what the hell. I haven’t seen one of those outfits for a long, long time. Takes me back.
