He was also weak and fragile in a fight. Another problem is that it seems the writer(s) stopped writing for his character after his introduction and his Jedi Conversion.
@valas991 ahah nice to know you feel the same! @Mellowtron11 yeah, though there is that encounter with Mandalore (TSLRCM) that shows them fighting about the Mandalorian Wars, which gives him some characterization. Mira is even worse tbh, like GO-TO has more content than Mira.
