sorry if there is already a thread for this but couldn'd find it. just wondering why : 1) they chose poweglide, onslaught and silverbolt as ultra class? are there any specific reasons? 2) both silverbolt and onslaught suppose to be the leaders of the arielbots and combaticons? or are they different characters? 3) are they going to make the rest of the teams that can combine to become superion and bruticus?
