Remarkable find! I never realized this, and it may be worth revisiting the Nobua Articles for Creation proposal.
Probably worth noting that from a canonical perspective, it’s difficult to say for certainty which (if either) of the comic Matoran can truly be said to be Nobua. For one thing, both of these comics take place within the same period of time, coinciding with the Toa’s fight against the Bahrag. With Ga-Koro under siege, it’s doubtful Nobua could have gone from Ta-Koro to Ga-Koro during that time. That said, it’s certainly possible that the artists nevertheless intended for both of these to be the same character, and it’s just a continuity error. Still, without direct confirmation, I think saying both are Nobua would needlessly cement this error on the canon.
Beyond this, I do think the Templar animations are almost certainly referencing Nobua, given their coordination with Safire. Great connection.
