SCP-7333, The Business Lizard Object Class: Euclid Form: Animal A lizard SCP managed by Mercer. It can speak and enjoys watching TV, but otherwise seems to have no particular abilities. However, one day SCP-7333 suggested buying a failing stock; Mercer ignored it at first but tried buying some for two weeks just in case, only to find the stock had risen several times over. Mercer now uses this to earn money through stocks, and the SCP Foundation also uses it to secure budget funds. SCP-7333 claims to have been one of three ancient gods; as human interest shifted from gods to money, two of them weakened and died, and the remaining one took the form of a lizard to bring happiness to people, becoming the current SCP-7333.
