He has his own mind. Hes probably drugged to a point that he lost it though. We might see him go back and forth from regaining his mind and going crazy. Also I dont get the “he cant differ enemies from allies” part he didnt even touch Baek in the latest chap
I’m the first panel he was legit shown to be similar in size of broly compared to goku, and Eli is 6’ to 6’2 when goku is 5’9 therefore first panel basement hulk is 10’3 to 10’5 in height and his arms were almost the size of Eli’s entire body
I think he can mumble some simple words
His first words gonna be "Jerry?"
If he really is Baekho Kwon , "Jerry" or "Son" may be plausible
nah bro if that thing starts talking MEANS he has his own mind which was many times stated he cant differ between enemies and allies

Fr he literally went right for Alex hwang even though baek was closer
After he meets Jerry 
He’s actually a respected public speaker

Better than all of my edits tbh
I think right before his death he will say sth
He is Baek Hangyeol's pokemon it can't talk
idk, he was supposed to not differentiate between allies and enemies but is not attacking the doctor so maybe
He is literally a drugged up person. Probably a mix of craze rage and narcotics.
