Popuko won’t fare any better than Pipimi did. She talks a really good game, but at the end of the day her abilities aren’t all that impressive. Ryan would only need 1 Mecardimal to defeat her and it doesn’t even matter which one he picks. Once he activates his final ability Popuko will be down for the count. She may be a solid singer, but that won’t be enough to change her fate. Ryan wins.
