This is my list for Top 6 strongest titans shifters, some of you guys may disagree and too normal becuse it's still my point of view, so if any of you have other different ranking for the titans, please dont hesitate to put it in comment below with argument!
1. Colossal Titan
In my opinion Colossal Titan is the strongest Titan we've seen so far, so freakin' huge and terribly strong.
2. Armored Titan
3. Ape Titan (Beast Titan)
Not much is known about this Titan, he is quite "new" in the story but he seems to be physically very strong (throwing pieces of the wall at a castle far away) and the smartest Titan to have appeared yet (he's the only one to speak the human language and he can somehow control "normal" Titans).
4. Female Titan
hardening ability and beating the Rouge Titan in 1vs1 battles..
5. Rogue Titan
He can go really mad and unleash all of his power to maximize damage and destruction.
6. Dancing Titan
Probably the weakest Titan Shifter we've seen so far, compared to the other Titans this one is quite small and doesn't seem to be very powerful.
