I tend to agree. I feel like the best time for him to have used Mega Evolution would've been in the XY saga, but that didn't happen because of Satoshi-Gekkouga. Him using Megas now would be interesting, but I don't think it's going to happen.
The same could be said of him using the gen 1 pokemon he currently has, and Riolu/Lucario during their respective gens instead of now, but this generation isn't playing by standard rules, and I like that.
sure it's not 100% he'll get a key and mega stone, but you can't write it off as impossible either.
I agree this is another reason that I want Ash to get Grookey so that it can evolve and maybe it can follow a pattern that one person on Twitter mentioned. That is Gen 6 had Ash’s water starter fully evolve then Gen 7 had the fire starter fully evolve, now in Gen 8 it’s time for the grass starter to evolve.
At the same time Ash has never gone with just a fire starter by itself, but has gone with Grass (Treecko) and Water (Froakie) unimpeded by other other starters to "effect" thier growth, but he didn't exactly get Scorbunny this time now did he?
Honestly i'd rather Rowlet come back and evolve than Ash get Grookey at this point, since see Ash not get a new gen starter would also be quite refreshing since those three always seem like a "dead lock" for him.
I agree with you about the fire type bias and have been sick of not seeing the water starters with the exception of Greninja on Ash’s team not evolving.
Evolution isn't always everything, despite the fact that i still regard Torracat's evo as being "Metal as ****!" I would honestly say Rowlet came out of Alola with a more helpful resume since it helped Ash in multiple trials where as Litten only had one to it's name.
With SM having passed it's prime i don't see why they can't evolve the little bugger now, and it's not like coming up with a plot to do it would be all that hard, all you'd have to do is have it failed an UR mission because it can't keep up with the others due to the limitations of it's current body, thus it decides to let go of the everstone and evolve to get stronger.
IF an I really disappointing that out of all the starters that Ash has had the water types get the short end of stick. This is why I want Marshtomp to get captured so he finally get a second water starter that is fully evolved, but oh well.
Greninja should've been epic, but they highjacked it with the AG concept...heck it was the only water type other than Kingler to evolve under Ash's command as well which was even more sad.
I dunno about Totodile, Oshawott, and Palpitoad, but Corphish obviously didn't go due to it's evolution being constantly shown in a negative light, both by team aqua and even other trainers following hoenn, Buizel smoked it's evolution so badly it only needed one puff, and Squirtle's got the squad to lead.
I honestly think that if it and Bulbasaur ever do evolve at this point, they would have to be forced to against their will since I honestly can't see either going through with it voluntarily.
Speaking of water pokemon, i wonder if Suicune is the mystery mon linked to Koharu's past, after all Gou said something happened to Koharu to make her "distant" to pokemon, and I would assume a pokemon was responsible, thought it was maybe the lake pixies from sinnoh (especially given how emotionless she acts at times) but that would be overkill.
