We just became best friends.

There’s another line aside from Grogar saying “I don’t trust anything any of you say” that might mean something:
 

 
When you put those two together…

That last one in cons could be his flaw that would help twilight

@MasterNexus  
That would be a really nice callback to all the previous episodes where friends were helped. Though personally, I always preferred the episodes where the Mane Six go through some sort of friendship problem and work through it themselves.

@Background Pony #02DE  
Yeah. 69, 420, that 6-digit anime meme, 13, and 50.

@SilverStarApple7
 
Can you tell me the lottery numbers?

I really hope they don’t mess this up. This is the last MLP season before they reboot the show badly under crap writers. This is their last chance to be epic.

‘Gain their trust’? That assumes that Chrysalis, Tirek, and Cozy trust anyone besides themselves. With those three, terrifying them into obedience is probably the better course. I mean yeah they’ll betray him eventually but until then they should be reasonably loyal.

@Background Pony #F238  
Yeah.

@LaszlVFX  
Plus, after Sombra’s defeat, Grogar made an example out of it if Chrysalis, Tirek, or Cozy Glow were to cross him.

@Background Pony #B308  
Because the characters from the movie are a movie exclusive characters. Their VAs was only paid to voice act in the movie and not in the show. Hasbro has no intention making the characters from the movie show up in FiM.

Another con: Why didn’t he revive the Storm King, or at the very least explain why he didn’t?

@AC97  
Yeah, that also could be a reason why.

I think it might be up in the air, if you should take that storybook Twilight was reading with some skepticism, that is to say, not be surprised if it didn’t happen exactly as portrayed in the little we heard of it, since his reign was so long ago.
 
@LaszlVFX
 
Specifically, Grogar probably waited until now because he had a few villains at their absolute lowest points, one of them dead (though Sombra ended up pissing him off with his attitude, so I wouldn’t be surprised if that was also a factor for leaving him dead, other than Sombra not listening to him, by not stopping after his Crystal Empire invasion failed), two of them in Tartarus, and one in exile and gradually losing sanity.
 
He is, to put it bluntly, an opportunistic bully (which is also why he favors ruling with fear), and I’m guessing the “betray Grogar” plan is something that won’t end up taking him down, regardless of whether he’s fully aware of it happening now or not.

There are multiple ways to gain respect, fear is but one of them. The problem arises, however, if someone ever decides they hate you more than they fear you. If that happens, then you have a potential problem.

He’s gonna create a darker version of the Weirdmageddon once he recovers his bell. I just know it.

@PurpleWonderPower  
Someone hated Grogar even in G1…

I think he’s all cons and no pros. I think the show should’ve wrapped up Cozy and Chrysalis in their own two-parters instead of doing this Legion of Doom thing and introducing such a bland villain.

“Why didn’t he revived Sombra again?”
 
He didn’t revive him since Sombra proved himself to be unworthy for Grogar’s plans since his plans include a lot of team-working. He was way to stubborn and egotistical to even realize what Grogar was saying. A villain like him would be a back-draw and a liability in his team.
 
“Spends more time that actually doing something”
 
Yes, because he’s a cautious villain. He wants to make sure about everything before attempting anything. Meaning that he wants to prepare for any surprises from the heroes’s part.
 
“What took him so long?”
 
He was too weak to do anything. He just now regained enough power to start his plans. He wouldn’t just get into a battle without his power not being restored enough.
 
“He didn’t watch Tirek, Cozy Glow and Chrysalis through his crystal ball?”
 
Yes he did, but he’s just playing along with them so he can make them feel unsuspicious. He obviously waiting them to start executing their plan and when the time gets right, he’ll unexpectedly strike on them. He’s actually way smarter than we think.
 
“Uses fear to boss them around”
 
Yes, since he wants to intimidate them so they’ll get a better motive to start working together. If he would just take it easy, they wouldn’t star working together willingly.

@ApplejackFan204  
Is it not the fandom way to overanalyse things?

@Background Pony #A104
 
It’s only one of the ways.

@ApplejackFan204  
Apparantly.

Using fear to boss around is actually helpful. This is how you get respect.

You got all of that after just three episodes featuring him?
