Together with his sister, Sarah Weintraub, Michael grew up in Vault 21. After Mr. House opened the vault, Michael started to work as a designer of neon signs for the Strip's many establishments, often taking "special orders" from Mr. House himself.
Like his sister, living inside a vault all his life has made Michael an agoraphobic, which means that he is afraid of wide open spaces. Compared to his sister, Michael has the more severe form of agoraphobia, as he even has problems working on the main production floor of his workshop because of its size. Thus, he can usually be found in the workshop's back room, while his assistants, including Kate, work in the main hall.
When first encountered by the player, Michael is lacking inspiration. Talking to the player, with years of costly therapy being out of the question, he realizes that he might regain his inspiration by studying sights he hasn't seen so far.
Michael Angelo can be blackmailed through a series of speech/repair checks upon the first meeting. The series consist of: Speech 40, Speech/Repair 45, Speech 55 will net you 300 caps and 140 XP. You will however no longer be able to interact with Michael Angelo, and thus be unable to attain his quest. If you choose to tell him you are just kidding at any point before you tell him "300 caps it is", you will abort the blackmail.
"I always wanted to see the Dinosaur and its Thermometer sign at Novac. Then, there's the famous Bison Steve sign. The McCarran Airfield and the Helios One power station signs are of much interest to my work - like the Sunset Sarsaparrilla Headquarter's bottle."
