So it's been brought up a few times in this thread, but I wanna spell it out for the people who haven't seen it. Generally people being angry about shipping is misplaced, but I'm pretty certain the writers of Thundercats 2011 purposely bred a shipping war.
Lion-O in the 2011 reboot of Thundercats got the rawest fucking deal. Lion-O starts out the series being berated by his Dad, and treated like shit by his brother Tygra. (Mainly for not being a huge racist by the way.) Putting aside how Lion-O is nearly killed by his brother twice, does get killed once, and ends up in despair in the finale of the show, Lion-O loses in the game of love twice. The first time to his brother, almost immediately after his brother tried to kill him. (Said brother never experiences any consequences for this.)
This needless to say, made shippers pretty mad. Tygra was never likable, and the writers pulled the filmiest excuse out their asses to have Cheetara fall in love with him. There was no buildup to it, and Lion-O literally stumbles upon them in the act of making out. This is after an entire season of Lion-O and Cheetara flirting. (Coincidentally, after this Cheetara basically became a background character.) Needless to say, people were angry.
But then they introduced Pumyra in season 2.
And shippers were happy. Pumyra was cool, and bounced off Lion-O well.
Then in the finale of the show, Pumyra betrays Lion-O. Not for a mysterious third party. Not for her own gain. To help Mumm-ra, the person literally responsible for killing her way back at the beginning of the show. The fact that Mumm-ra says Pumyra was literally his, body and soul, is also super weird. So Lion-O loses the second love of his life to an undead mummy.
Here, Pumyra is kissing Mumm-ra's "power gauntlet."
But wait, it gets worse for Lion-O! The show was cancelled after this due to poor toy sales, but apparently if the show had continued, Mumm-ra would have transformed Pumyra into a winged insect monster. She would later be killed by the Thundercats.
The Thundercat that would kill her?
Tygra.
