Imzadi must be up there. Established Riker's middle name as Thelonius, which was invalidated by Second Chances about 10 months later.
And I have a vague recollection of Riker having both "Thomas" and "Thelonius" as middle names.
In a zigzagged way, no and yes. In 1992's
Imzadi by Peter David, a computer stated the full name to be "William Thelonius Riker". After 1993's "Second Chances" blew this out of the water with "Thomas", 1994's
Q-Squared, also by David, tried to smooth this over by having Picard address him as "Commander William Thomas Thelonius Riker". Interestingly, David's
Triangle: Imzadi II in 1998, which featured Thomas Riker, did not acknowledge "Thelonius". For his part, Jonathan Frakes narrated the audiobook version of
Imzadi, and just last year he
joked on Twitter about Peter David's origin of the name homage: jazz musician Thelonious Monk.
This feel somewhat parallel to the DIS
Enterprise scenario. 2017's
Desperate Hours by
David Mack had Georgiou's
Shenzhou meet Pike's
Enterprise a year before the outbreak of the Klingon war. 2019's
Discovery season 2 set up a new premise for Pike's
Enterprise meeting the
Discovery after the conclusion of the Klingon war. Burnham and Spock do not acknowledge the events of
Desperate Hours wherein they overcame some sibling tension; Burnham states to Sarek that "it has been years" since she has seen Spock. By contrast,
The Enterprise War by
JJMiller has Spock think to himself that "it already felt like many years since [the events of
Desperate Hours], and he expected [Burnham] felt the same way". I am not sure if this massaging feels believable to me, though to be fair, the
Enterprise crew was being dragged by pseudo-religious zealots through a good year's worth of hell.
