- Anvilicious: Taking into account what Steve Gallacci has said regarding the backstory of the comic, the main message of the comic is basically that the anthropomorphics are condemned to repeat the mistakes of their human creators, no matter what. Now the new protagonists have to solve the whole mess their ancestors failed to do in the past.
- Hilarious in Hindsight: Regarding the similarities with Yoshiki Tanaka's The Heroic Legend of Arslan, Steve Gallacci originally planned to end the story with a Kill 'Em All ending, something that he ended up changing his mind later on, and he went to the opposite direction. On the other hand, the novel version of Arslan was infamous for doing the opposite, and the novel ended with most of the main characters, Arslan included, dead.
- Spiritual Adaptation: A very curious one: If Albedo: Erma Felna EDF can be considered as the American equivalent of Legend of Galactic Heroes, then Birthright can be considered as the Western equivalent of The Heroic Legend of Arslan, except Recycled IN SPACE!. Interestingly enough, both works were written by the same author, Yoshiki Tanaka.note
- Spiritual Antithesis: Just like Albedo, the story bears a similar plot with Tanaka's The Heroic Legend of Arslan, but that's when the similarities end:
- Unlike Arslan, Alfon has a much small number of named allies, (besides his nameless allied soldiers, there's his girlfriend Jenna, his mentor Duwan who gets killed during the first arc and much later, the crew of the Winkles), compared with his human counterpart.
- In both stories, the protagonists' parents are held hostage by the enemy invaders, but the way they treat their children is very different. In Arslan, the titular hero's father, King Andragoras, exiles him after Arslan rescue him, while in Birthright, his anthro equivalent, King Anton, is more than happy to see his son again after he frees him with the rest of his family.
- Likewise, the invaders in both stories, Ebontoa in Birthright and Lusitania in Arslan, both want to conquer their enemies and take over their lands, but are treated differently in their respective stories. Unlike the Lusitanians, the Tosiu army has only a single named character, General Rau, who isn't given as much depth as his human equivalent Guiscard. Also, unlike The Starscream Guiscard, Rau is blindly loyal to his country, and he sacrifices his life for his ideals, despite having all the odds against him at the very end.
- In Arslan, there's no equivalent to the crew of the Winkles, much less of its on-board Artificial Inteligence.
- Unlike Arslan, Alfon is the biological son of his father, compared with his human peer.
- And finally, unlike Arslan, Alfon and almost all his followers survived at the end of the story. The same cannot be said about his human counterpart.
YMMV / Albedo: Birthright
