So....even in stories that use Tang Shen and Yoshi's relationship in stories, they seem to scrap Oroku Nagi, Shredder's older brother who's murder at the hands of Hamato Yoshi for crimes against his beloved sparked the whole feud between the Turtles and Shredder in the first place.

Since he's easily supplanted by his own brother (in the 1st movie and most recently the Nick toon.) or some generic orphan "brother" to Yoshi himself, does the Turtles lore even need Oroku Nagi?
