I actually feel a little bad about this pick, since it’s the one EVERYBODY makes. At this point, being a Digimon fan who complains about Meiko is a bit like being a wrestling fan who complains about Roman Reigns. It’s such a cliche that it’s honestly a bit lame to keep on doing it… and yet, here we are.
I mean, good God, Meiko is a worse self-insert fanfic character than most actual fanfic self-inserts. All this character does is take over scenes, receive affection from the established characters, and feel sorry for herself in a calculated attempt to generate audience sympathy. Really stop and think about it for a second: if you removed Meiko from Digimon Tri entirely, if Meicoomon were just a stray Digimon running around on her own, what would actually change? What affect does this character have on the plot that wouldn’t have been achieved via other, previously established means? She’s completely and utterly POINTLESS!
And believe you me, it takes a LOT for me to dislike a character worse than I already dislike most of the goggleheads. I think Tai and Davis are utter jokes compared to Matt and TK. I think Masaru is a charmless idiot thug. There are debilitating childhood illnesses that I like more than Tagiru. Yet, even taken together, none of them damaged their series to the degree that Meiko did.
…although, at the very last minute, Meiko DID manage to infuriate Tai/Sora shippers, so even she’s not ALL bad *evil laugh*(If that rant didn’t drive you away, then be sure to read all the other Conventional Wisdom comics, and maybe even donate on Patreon!)
Granted, I did once joke about Tamers as being the self-insert fan-fiction of Takato, except the entire point of Tamers was basically the idea of Digimon existing in the real world. Plus Takato, a fan of Digimon, at least faced the consequences of bringing a monster to life and unintentionally brought himself into a very dangerous world where a popular franchise about monsters was VERY real and that said monsters actually posed a threat to the world, ultimately culminating in the main cast fighting an eldritch abomination driven entirely by the primordial instinct of it's programming.
You could take Meiko out of Tri and nothing would change. You couldn't take Takato out even if you tried, because Takato creating Guilmon back in the first episode is literally what kick starts the entire plot of Tamers. Meiko is pretty much the polar opposite of Takato, because while Takato is a fleshed out character that starts out as a fanboy that realizes he doesn't know what he's getting into, Meiko is just a waste of space.
To me, none of the goggle boys are bad (except Tagiru), they just make a number of stupid decisions.
