Spark

supposedly  built by someone with access to Doctor Order's  blueprints, the end goal  of Project: Spark was to make an evolving  robot that could learn from its failures and gather battle data that  could be used for self-improvement and also as a basis for other  creations. in practice, Spark's win/loss record is less than ideal and kie's in constant need of repair. kir creator's solution to this  problem is to rebuild kir and  give kir access to new abilities each time kie gets wrecked, but while kie's sometimes able to use this to kir advantage it usually results in kir mixing up what moves kie does and doesn't have access to and getting KO'd.

kie's driven by a need to impress people, and will pull off  reckless moves or throw tactics to the wayside if kie thinks kie's got a shot at doing so. sometimes this works out in kir favour! usually not. kie tries to not let that slow kir down, though.
