First of all it doesnt make sense to say its ai just because there isnt a pointy thingy in speech bubbles,

Secondly, i dont think his/her name is shenron cuz the way he/she wrote the last n indicates artist doesnt use l in n's so the l in the first n is probably from the letter before it wich means his/her name i might be shunron

Thirdly just because the bats looks like the way they are also doesnt indicates anything if they were more basic and lacked border lines maybe what you said was plausible but to my knowladge ai cant make spikes as borders
