With the OT, most to everyone would agree it's the lightest cartoon version of the TMNT, but after watching a few episodes I noticed that in some of the dialogue, the characters (minor or villian though) had dealt with death. Here are some examples:
"Shreeka's Revenge" - Shreeka becomes upset with Krang and has a punishment "worse than death" by returning Bebop and Rocksteady to Krang. So she must have been familiar with killing others then... I guess...?
"Night of the Rogues" - Krang's executioner from Dimension X. Therefore, he must have killed prisoners or enemies within Dimension X.
"Poor Little Rich Turtle" - Buffy Shellhammer's grandfather passing away and giving her the formula for an explosive.
So besides these examples, are there
any other occurrences in which the dialogue or backstories may have suggested/implied that any of the OT characters had experienced death? It's actually interesting that the OT wasn't
completely free from dealing with the issue, but of course these moments were
so insignificant/unnoticeable to the overall light tone of the series.
