For me without a doubt the weather witch third and second attack "TEMPUS BARABUBAAA" and "EREM BREREM, EREM BARBARO" I somehow dont really remember the sound for the first attack, I think she just says nothing
After that probably the fire mage and the mage archer. (They sound kinda similar too imo)
Creon have the funny sounds in general, like chief engineer "OK OK, I'm going", the mechanic "When do we eat?", "Have YOU ever carried one of these??", "That's easy for you to say..", "This thing is heavy." sounds like the mechanic really hates doing his job lol
I think the fire wagon says "How do you like your toast" (poor english here, maybe mishearing)
And the neo dragon "Let's use the frozen death wave".
And most importantly, the Automatons sounds to me a lot like those star wars droids somehow
- Spoiler:
Seriously go listen to the automatons (IPEnglish.hpi)
