It can only be said that the designs of RX-78-2 and ZAKUⅱII II are the earliest mobile suit series machines, so both of them have an influence on the rear design. Therefore, in order to attract many early audiences, the later works naturally adopt many similarities with the previous works. This is the main reason why this series of mobile suit-Gundam can be realized. Gundam is used to attract many new audiences (because Gundam is handsome-partly because of course), and Zagu is used to attract many fans of the fuel system (Zagu is mostly mixed-race, so there are many burning lines or pictures-for example, in Gundam 0080, Barney beat NT- 1 Alex Gundam in Zagu II, and many people naturally produced "If it is a man, open Zagu." ), so the above two machines have been modified countless times before they can be used now ... The above explains my point of view and hopes that the landlord will adopt it.
