Iode

The eldest of the Cyber Girl Three Sisters, as well as the ultimate enemy of the Cyber Girl-type, the Iode finally does away with the weakness of this monster type by not having anymore the Trip&Fall skill. However, she is a marginal improvement over the Sayri when it comes to stats, and her skill set is very similar: Drei Blade, and a new skill that hits a single party member four times called Highspeed Railgun, which can be a bit hard to block due to the speed of the hits. However, she still can be dangerous because she won't be wasting turns around like her predecessors, so caution is advised while fighting against her.

Trivia
Her name seems to be a truncated form of the word "Diode."
