Kabal is the fastest in the MK Universe and Blaze, Onaga, Centaurs and Shokans are the strongest in my opinion (would explain why Goro, Kintaro and Motaro protected the higher power in MK1, 2 and 3). As for Tarkatans they vary in speed and strength.

Yeah I'm not saying they have to be the strongest, because they shouldn't but they should have very impressive physical stats.

I know, like how they have a more solid skeleton (most are naturally ripped too) and the forearm cutters went from steel blades to hardened horny blades, although I still think the steel blades are more effectively beneficial. Not really a 'physical stat' but scent detecting is something they all innately have, although their endurance ranges.

Yeah they do have a good sense of smell as we know from Deception. This makes me wonder if Mileena is physically stronger due to her Tarkatan side.

If anything I think her olfaction would be weaker because she's not a natural full-blooded Tarkatan.

Weaker compared to full blooded Tarkatans yes. But I'm thinking compared to Kitana and Jade. Maybe she has the edge in strength and speed.

It's not their strength. They're very spiritual.

Strong sure, but I don't think they are fastest than Reptile, to make a comparison. I think his skeleton being more bulky makes them heavier than a human of the same proportions. Something very cool is that the Tarkatans could be explored more. We already know that they are a tribe, the strongest one becomes the leader, they feed on meat only, they have sacrifice rituals and are very superticious, but they don't care about pure blood since they accept Mileena as one of them. I wonder if they have more ranks inside the tribe.
