"Paclum hold many curiosity about his body as his master was wondering about since he have dna of Aggron his master wonder if he can use a megaevolution and for her surprise he did! he could mega evolve but then she realize Paclum have a second personality at difference from the inocent and calm paclum the megaform have its onw personality and complete mastery of all of his body powers"

Paclum? - Finally free! i was sleeping for so long i itching for a fight bring it! metal, water, electricty, ground choose which type you want me to use or i can use all of it! and you better watch out i may have shrunk in size but is dont mean i cant grow even bigger! and i can still capture you even bigger preys!

Silly idea i been having the idea for quite sometime since he have all that mix of Adn in his body i imagine he could also use mega evolution and dynamax but at difference he can use it at will dont need galar particles but he can only use for short times if is the whole body but he can use it in any part of his body wihtout time limit and yeah the megaform have different personality a more cocky one that know inside out his onw body
