Pippin and Cuckus are pretty average. Whilst they serve their purpose in the narrative well as a silent badass and a conduit of the average Band of the Hawk member, neither have much development beyond that.
5/10 for both
Rickert is slightly better. Whilst not standing out too much in the Golden Age Arc, his role as a survivor and support for Guts, as well as coming to terms with Griffith's crimes gave him some nice development. Confronting and slapping Griffith was one of the best moments in the past few years of the manga, and with him going away with Silat's group, I expect him to get some focus from a training arc and a change in perspective from staying with these guys.
5.5/10
Judeau is significantly more well written than the three already mentioned, playing the ideal support character role. He acts as constant emotional support for the Band of the Hawk throughout most of the Golden Age, being able to read people and see what the best course of action for maintaining peace is. His conversation with Guts and his displays in battle show him as a jack of all trades, master of none, helping hype up Griffith's charismatic nature even further. His death was probably the most tragic in the Eclipse, with him dedicating himself to saving Casca due to acknowledging the importance of the Band's leadership over his own life and having not got the chance to express his feelings to her.
Still a cuck move that he gave up pursuing Casca to let Guts bang her though.
6.5/10
Casca is a good example of how a female character should be written. Whilst she initially comes off as overly bitchy, often chewing Guts out for the slightest mistake, her background does serve to justify it, with her having made the choice to join Griffith over a life of servitude and weakness due to one choice being obviously more beneficial. This can even be seen as somewhat tragic, with it being made apparent that regardless of what choice Casca made, she'd be forced to live under the will of a superior. Going on from this, she's one of the few good representations of a woman being trapped by the status-quo in terms of social and biological standards, such as her menstruating during the battle against Adon showing how much of an effort and struggle she goes through to fulfill her role. Whilst it can be considered somewhat cheap that she's both dark skinned and female to help highlight her role as a complete outsider in this world of war, it still helps push the idea that she never truly fit into either walk of life. The dark skin would also go a long way in aiding in Guts' development when her relationship with him became romantic, because....
On that subject, one of the main aspects that enhances Casca's character is her dynamics with the rest of the cast, particularly Guts and Griffith. Their reactions and constant conversations help make their development throughout the Golden Age all the more believable, such as Guts and Casca's romance being a lot more believable with such moments as them both witnessing Griffith saying none of the Hawks could truly be his friend or how Guts confided with Casca on his lack of purpose in the "Campfire of Dreams" scene. Going back to Casca's irrational responses and jealousy towards Guts in the earlier events, it's not as though this is the only setting for Casca's personality. More often than not, she's presented as one of the more logical members of the Band, calmly chastising characters such as Corkus for making stupid decisions and thereby acting as a voice of reason.
Overall, whilst not quite as good as Guts or Griffith, Casca is easily one of the most well rounded, fleshed out and developed characters in the series and one of the few cases of pushing a strong, female character that has enough characterisation and depth to them to come off as successful rather than pandering. Shame that the Eclipse caused her to stop developing by going Potato for 20+ years.
