Splinterson

Splintersson is a patronymic used by the Ninja Turtles in the 4Kids television series. Its use is infrequent and is thus far exclusive to this continuity.

Leonardo first mentions that the Ninja Tribunal call him "Leonardo Splintersson" in the voice-over introduction for More Worlds Than One. In Timing is Everything, Donatello addresses an envelope from "Donatello Splintersson" and to "Michelangelo Splintersson."

Peter Laird had this to say about the patronymic in his notes on More Worlds Than One:

"The more I see the names the Turtles are called in this script, i.e. "Donatello Splintersson", the more I am unsure I like them -- they're sounding kind of Scandinavian or something. I'm not saying that this works perfectly, but might we think about giving them the "Hamato" name as we gave it to Splinter in the "Big Brawl" episodes, i.e. "Hamato Donatello"?"
