I think I understand why the lack of Pulonia upsets me.
It’s because the new robot lacks something that Pulonia had in spades.
Intimidation Factor.
Sandrone is a very unthreatening looking individual, and at best looks like an annoying brat of a harbinger, that is until you consider the fact that she has a massive robot that answers her beck and call right with her at all times.
The new robot, being significantly smaller than Pulonia, lacks that same intimidating stature.
Overall, I am glad Sandrone gets to be playable, and from what I can tell, she’s still the same bratty tsundere she was before, if animations are anything to go by, but it is a shame that the bulky intimidating yet reliable look of Pulonia was replaced with a polished yet frail looking sci-fi maid.
