he kinda inherited some of zeke's spinal fluid i think and so he kinda have some beast like titan characteristics in him
if you remember tom xavier, the beast titan before zeke, he's a scientist and he kinda accessed some memories abt beast titans being diff animals as falco drank the wine that has zeke's spinal fluid he inherited some genes ig and combined it with the power of jaw (since he ate galliard too)
ohhh I see thank u so much ... maybe I should reread it againnヾ(❀╹◡╹)ﾉ~
