Roy Föcker was named in honor of the Fokker aircraft company, and its founder Anthony Fokker who built the Fokker E.I, the Fokker Dr.I and Fokker D.VII fighter aircraft during World War I.[9] In flashback sequences, Roy flies a reproduction Fokker D.VII, and gives Hikaru a model of one as a "get well" gift. Furthermore, although several possible scenarios regarding his death abound, the Red Baron (for which the Fokker Dr.I was most famous) was possibly shot down in combat by a Canadian pilot called Roy Brown, the origin of Roy Föcker's first name. RoyFöcker的名字是为了纪念Fokker飞机公司及其创始人Anthony Fokker,他在第一次世界大战期间建造了Fokker E.I,Fokker Dr.I和Fokker D.VII战斗机。[9]在闪回序列中,罗伊飞过Fokker D.VII的复制品,并给予Hikaru一个模型作为“得到好”的礼物。此外,尽管有关他死亡的几种可能情况比比皆是,但红色男爵(Fokker Dr.I最着名的)可能被一名名叫Roy Brown的加拿大飞行员击落,这是RoyFöcker的名字的起源。
