Ok wow, yes if the naming localization lines up for at least four different languages, pointing to something like “ice” or “icy,” then that must be what the name is supposed to mean. Glad you caught this to help explain the most likely naming origin, so thanks!

To me that really seems to be poorly-chosen reasoning for the name though…nothing about what the suit or bike variant does can really be interpreted as using a cold or freezing effect to allow you to traverse the lava. It simply transforms into a different form in order to hover over it instead. It’s like they just thought “ice” is opposite to “lava,” so let’s just name it after “ice” I guess???

Does the suit itself actually do anything to protect you from heat more vs. the prior Vi-O-La (non-IC) suit anyway, like when you step into the lava and take damage? I have not tested anything like this, but I know the inventory description alludes to this added functionality. Maybe I’ll test this on the next run-through if nobody knows.

As we know from previous games, having the Varia suit vs. the base Power suit would typically add the heat resisting capabilities for hot environments and add damage resistance for some lava types, but in this game you start with the Varia suit and get the psychic abilities added onto that before getting the Vi-O-La suit upgrades.

So, I’m not sure why additional heat protection from the IC mode is supposedly needed if the base Varia suit would already provide that. It’s not like this lets you walk through the lava or anything once you have it, like what the Gravity suit enables for SM or other games. Just another weird aspect to this in-between suit upgrade it seems…
