Excuse my poorly alliterative title. :^P Anyway, here's the question - I don't recall reading anything anywhere about the rahaga and Keetongu doing anything about the mutant Rahi that would've remained after the Visorak occupation of Metru Nui - and that is a problem. It means that: 1. Mutant Rahi should've appeared on Mata Nui. A few would've moved out of Metru Nui, which probably ran out of resources to sustain them after the Visorak and Toa Hordika (but mostly the Visorak) trashed the place, to the more fertile and resource-rich Mata Nui for snacks. 2. The increased power levels and aggression of the mutated Rahi would've made them akin to invasive species in real world ecosystems - they'd wipe out the normal, unmutated Rahi that escaped the Visorak by getting onto Mata Nui, causing the whole Rahi population of Mata Nui to be devoid of non-mutants. 3. Mutant Rahi would've been a threat when the Matoran returned to Metru Nui post-Mask-of-Light. So, yeah. I'd appreciate input on this.
