I could do the various incarnations of the Doctor in Doctor Who. An example info-dump from memory without looking stuff up:

So the first Doctor was played by William Hartnell, and later Richard Hurndall and David Bradley after Hartnell passed away. Second Doctor was Patrick Troughton who (tangent incoming) originally pitched playing the second Doctor in black-face which thankfully got nixed. Third Doctor was Jon Pertwee, Fourth was Tom Baker who is still the longest-running Doctor by episode count, Fifth was Peter Davidson, Sixth was Colin Baker, Seventh was Sylvester McCoy although (tangent 2) he also played the Sixth Doctor for the regeneration because Colin Baker got fired and refused to film his last scene so the Sixth in that scene is just McCoy in a wig. Eight Doctor was Paul McGann who was the longest-running Doctor chronologically even though he’s only been in one full episode (the 1996 TV movie) because the show didn’t come back until 2005. He’s done some cameos in the show since though. Ninth Doctor in canonical order is John Hurt, although he was added in retroactively during the 11th Doctor’s tenure so he’s referred to as the War Doctor instead of the Ninth. Tenth Doctor canonically is Christopher Eccleston, who is referred to as the Ninth Doctor because of the aforementioned retconning. Then it gets complicated. David Tennant is the Eleventh, Twelfth and Sixteenth Doctor because he regenerated into himself and then came back again later on, which we’ll get to in a bit, but he’s referred to as the 10th and 14th Doctor. Thirteenth Doctor is Matt Smith, who’s referred to as the Eleventh. He was also supposed to be the Doctor’s final life because Time Lords are only supposed to have 13 of them, but then he got a new cycle of regenerations because it would be silly to end the show because of some arbitrary plot point from the 1970s. So then Peter Capaldi was the Fourteenth (or First if you want to start counting again from the new cycle, which nobody does) and is called the Twelfth. Fifteenth (or Second) was Jodie Whittaker, who in the show is called the Thirteenth. She then regenerated into David Tennant again (hence him also being the Sixteenth/Fourteenth) for a couple of specials, and then he split into two separate Doctors, the other one being Ncuti Gatwa who is the Seventeenth or maybe co-Sixteenth or maybe Fourth but is referred to as the Fifteenth in the show. He then (SPOILERS if you haven’t caught up to the last episode) regenerated into Billie Piper, who played Rose Tyler previously in the show and also a sort of sentient bomb called The Moment and who might not even be the Doctor at all, we don’t really know yet. There’s also all the Timeless Child stuff which throws off the numbering even further, and Jo Martin who plays the Fugitive Doctor who is possibly some sort of pre-First Doctor Doctor but the show never really explained it. There are also some other pre-First Doctor Doctors shown in flashbacks and things in The Brain of Morbius and The Timeless Child, but who knows if they’re even real or not. There’s also another David Tennant who is a sort of human clone of the Doctor who lives off in some parallel universe, and another Tom Baker who is a character called the Curator who seems to be some far-future retired version of the Doctor who revisits some of his old faces.

I could go on but you get the idea.
