Deryl when an enemy "hey hey Mc I have prepared a bunch a nasty shit for you take this and that and what not oh don't worry I already know your next move and the one after that" Deryl when an ally "here you go bro I put a whole forest on fire with my missiles whatever good that would do, oh no I got taken out of the sky guess that's it my big freaking bag pack mostly consist of my cool looking jet pack wings and some missiles my bad".
Deryl as a monster was dangerous shit
Even as a monster, he was intelligent, even more than he is now, a greater understanding to be exact, when it comes to monsters and how to use them to get stronger, everything he did, all his preparations and even his evolution - I'm not sure, so sorry if I'm wrong - were planned so that he could get stronger, as a superhuman, he needs time, his skills are not specifically for combat, but I don't doubt that in a short time, he will become one of the strongest and most dangerous superhumans.
