[FerrousMaelstrom]

Partial rereleases aren't too rare, but a full one like this is. IIRC,Kyuranger had quite a few - two Shishis (Kyuren-Oh took up two sets to get all the main voyagers, so repeat of shishi) then included a second Sasori in set 3 and 4 other repeat limb voyagers in set 5 for Cerberios. LuPat had Good Striker twice (1 and 2), and blue and yellow twice (1 and 5).

It seems like they throw in repeats if there's a mecha that can't fit in one set, or a movie mecha that uses some parts from the main one. I guess this is because TigerLance and MilNeedle still need parts from Toricane and Ankyloze but the fact that that's the entire set is still weird
