When you win the game as a yeek summoner who has the talent "summon control" and choosing the option to be killed rather than spread the way (I haven't checked if the same happens if you spread the way), you are given control of one of your summons, and a character sheet is generated for that summon. Here is the sheet for a minotaur I was given control of immediately after winning.
I'm keeping that sheet forever by the way- it's the only way I can be technically correct in saying there's a character in my history with almost 350 of a stat without addons or infinite dungeon.
Edit: Here is the summoner who was the winner
