Why didn't Mumm-Ra...?

I just thought it’d be fun to drop some ideas of what Mumm-Ra didn’t do but should/could have done to get rid of the TCs once and for all (of course I know he could just erased them from the face of Third Earth with just a beam, but I’m thinking in things he could have done in the episodes). Feel free to add to the list.

So, why didn’t Mumm-Ra…?

[li]Gave the Mutants thundranium covered armors and weapons? (He kinda did this in “The Mountain”)?[/li][li]Ordered teh TCs to throw themselves to the river or kill themselves somehow else when he had them under his power (“Mumm-Ra Berbil”, “Dimension Doom”, “Dream Master”, “Bracelet of Power”, etc)?[/li][li]Sent them to the sun or another planet rather than to “exile” in “Last Day”?[/li][li]Just get rid of Lynx-O, Pumyra and Bengali in “ThunderCats Ho!”?[/li][li]Slain every TC with Excalibur?[/li][/ol]
I’ll leave this here in case someone else want to say something.

I guess he didn’t want to kill the story … LOL :tongue
