Well, Eren Yeager is the 'coordinate'~ IMO, there is 2 possibilities what this coordinate ability can do~ 1st off, the Coordinate power 'maybe' (yes, maybe) refers to the ability of boosting the power / damage a Titan Shifter can deal for a certain time~

The primary or first coordinate was Frieda Reiss~ Based on the manga, Frieda was devoured by Grisha Yeager causing the coordinate ability to be transferred to him~ After devouring Frieda, Grisha then run somewhere else and inject Eren with the serum that triggers Eren 1st transformation as a titan~ After transforming, Eren (unknowingly) devoured partial parts of his own father and thus the transfer of the coordinate ability occurs~

As for the explanation on how this coordinate boost Eren's power, I think it is best explained when Eren was fighting Annie Leonhart~ Remember Annie (in titan form) crush Eren's (also in titan form) head and Eren was sitting on the damaged building saying he will kill them (titans) all? That is probably when he trigger the ability and somehow managed to chase Annie although he was actually still regenerating his limbs and arms~ In the anime, his body too was coated in something reddish, suggesting that it maybe some kind of other power that he has yet to control since Hanji told Mikasa that he (Eren) is not in control at the moment and that she should not attempt to get near Eren~

The 2nd possibility is that the coordinate ability is what allows Eren to somehow drive attraction from here (one place) to there / something (eg. titan)~ IOW, based on the manga, Eren punches the smiling titan that killed his mother and causes all the titans there to devour the smiling titans instead of the other present~

As for conclusion, maybe and just maybe, Annie too possess the coordinate ability~ Or the event where Annie's scream when she is cornered by the Recon Corps (while in titan form inside the Forest of Giant Trees) is simply a battle cry~ Possibly because she had nothing else to lose so she proceed with that drastic move in order to escape~ I'll leave you guys to think of that~

I strongly agrees that coordinate ability is as the 1st possibility I mentioned~ However, no one truly knows what will happen (saying this with Levi's tone lol)118.100.169.173
