I saw you removed Dehuai as a The Heavy. The character seems pretty cut and dry for the criteria, even with his own section on is long term effects on the plot, how it starts and his agency over ending the lives of several character's lives minor, and major. But I wanted to know why he was removed so I can reapply any crucial limiter to the category.
Alright - he kills several characters, including the main character's father, which continues to affect him, as well as killing a character from the second game - (time travel). And triggers the traumatic experience that has our main hero dealing with the internal balancing of Malice as a battle mechanic.
My apologies for the disturbance, but the character Aresia actually failed her 2 goals at the end of the 2-part episode "Fury" of Justice League as she died from the explosion destroying both her & her allegen aboard the jetplane. I watched the cartoons many times since my younger years. I know what I'm talking about.
the problem is Pink Diamond was a villain, way back, yes she was the "nicest" Diamond but she still willingly conquered worlds and enforced a caste system etc.. she improved over time because she learned that being a tyrant wasn't what she truly desired but originally she was part of a tyrannical regime.
Grogar may or may not of been real but every moment that we have seen "Grogar" in FiM has been Discord in disguise, meaning every threat that Grogar has been to the series is null.. it was all a con.
FiM has made it pretty clear that most threats that have ever happened post-redemption arc of Discord have basically happened because he either allows it to happen or he finds it useful to do so.. I'm unsure if even the Bewitching Bell truly harmed him or if it was, again, another con to spur heroes into action.
Grogar as stands is like a fairy tale, if anything, maybe it can be put up as such but it'd be of the legend - since real Grogar seems to be fake and quite possibly even back then it was Discord in disguise.. since Discord was shown to be more malicious way back.. it is likely "Grogar" was Discord, back in the day.
I seriously doubt Discord would go as far as to pretend to be Grogar thousands of years ago. He may have faked his injury in the season premiere, but I think he was being serious about being depowered in the finale.
Look, if this is such a huge deal to you, then I'll just wait until we see both episodes. Just be ready to return the page to its former glory if it turns out I was right. And if I'm wrong, then we'll move everything onto Discord's page.
Also, Pink Diamond only ever had one colony, and she never realized the consequences of colonization until she saw how beautiful the Earth was and the damage her kind was doing to it. She was more of a bratty, naive child than a full-fledged tyrant.
