I’m not a fan. The build is a basic inika buid with a sword, silver armour, barely any colour variation, and a mask generally seen as overused. Since you’re going for elemental silver you’ve missed out on a wealth of other colours you could use based on silver’s chemistry.
Some common silver compounds include silver oxide (Ag2O) which is pure black (a tarnish could look gunmetal perhaps), silver carbonate (Ag2CO3) which is bright yellow (keetorange, yellow or the really pale green from the skull spiders and morrow dragon might work for that). Some of its other compounds are white or brown… ok, so maybe it’s not that good for the whole other colours thing. Chrome pieces would definitely be a good touch though maybe.
Plus, a toa of elemental silver might be able to harness the electrical properties of the metal. Silver is one of the best conductors of electricity of all (the Manhattan Project used wires made of silver for this reason) so it’d make sense for him to have some sort of electrical power or attack. Plus it’s historically been a metal associated with nobility, wealth, power, healing (silver actually kills bacteria - it’s used in antibacterial bandages) and the moon.
This said… my own toa of silver wasn’t all that great… I made him in like 2009 and he also had an inika build, and his name was really, really unoriginal
AND HE HAD RED AND BLUE PINS AND NO EYES
