Definitely. They both have some pretty good one-liners too.
TEAM KAYNAR!!! You are like the toy that never breaks XD
WOOHOO!! Support!!
I wouldn’t mind seeing Cheetara go up against Kaynar, if only to recreate the scene where she tricks him into running into a big rock. 
Merged Post:
Here’s an idea for a new poll; compare the OS vs NS villains and see who deserves the “Most Improved” award.
Kaynar wins that. Not just because he’s my favorite, but because he was by far my least favorite in the OS.
I’ll take Kaynar vs. Pumyra. The insane versus the berserk. That would be one for the record books.
Most improved…hard to say since we haven’t seen the incarnation of Vultureman yet, if one is out there. But Kaynar is definitely the front-runner. While I always liked Jackalman, he was kind of the third stooge who was stupid enough to mess up a glass of water, and he seemed about as dangerous as a feather pillow.
So I got really bored and went on deviant and did a random search on Ratar-o and I found wtf drawing of him. http://browse.deviantart.com/?qh=§ion=&q=ratar-o#/d4z0jzz
That was weird. Very weird and slightly scarring.
Awwwwwwwwwwwwwww! That made me smile! I want to hold him in the palm of my hand.
That could easily be Mordax cosplaying Ratar-O:cool:
Although I do like Kaynar and Atticus, and frankly they are more menacing than Mumm-Ra at the moment, but I have to side with old bundle of bones :D. He has just something about him that I like, he’s fun even if he is silly at times. I hope they do something amazing (horrifying 
) with Mumm-Ra to make him more of a genuine threat than someone who can be defeated every time Lion-O uses the spirit stone.
I’d consider him a pretty big threat with the sword of Plundarr.
Wow Slithe is way behind.
That’s good!
Kaynar. Because i think he has the psycho factor down petty good. And he looks like a complete bad@^&.
Kaynar has the edge, despite not seeing him too often he has managed to win the audience’s favor! I like a lot his menacing and psycho profile.
My question is when are we going to see Grune again???
I question with you. Bring the sabertooth back!
Well now he is. Let’s see what he does. He succeeded in attaining the sword, but I was hoping by now he would have had done something more to cripple the Cats. I know he helped destroy Thundera and killed Claudus, but his presence doesn’t have that resounding impact if you know what I mean.
He will be even a bigger threat if he gets the other two war stones (which I think he will) before the Thundercats can get them.
