It's a new thing you can get as reward. They basically introduced crafting mats, if you will.

The transmetals (and weapon upgrades) can only be used for that, upgrades, but they seem to have a *huge* effect when upgrading (I used up 6 transmetals on my lvl 62 flamewar, thinking it wouldn't be that big, and she the gained the last 3 levels no problem; so now i'm wondering if maybe I wasted some :P).

Also, upgrading through characters can now use up to 20 characters at the same time (much more convenient!) but also seem to give less exp than it used to! I used 20x R2 razorclaws on a brand new Episode Razorclaw, and it only got him up to level 21... (before, just 8 of those would've brought an R4 to lvl 19 easily).
