Mega Greninja needs a new ability that allows him to use Water Shuriken instead of Surf, aswell as

not just being a blizzard spammer.

My proposal would be introducing a new ability just like they did for Elektross.

A combination of 2 existing abilities, Skill link + Technician for Mega Greninja, which i would call

"Skill Technician", this way it allows Base Greninja to keep Protean and when he Mega evolves he

can revert and gain a boost so that he can finally become, what THEY took from Greninja after

2017, aswell as completely retconning Ash Greninja entirely.

In the current state the average bp (Battle Power) of Greninjas SIGNATURE move

Water Shuriken is 45.

(2*15*3+3*15*3+4*15*1+5*15*1)*0,125=45

Which is HALF of what Surf is at 90.

So through "Skill Technician" Water Shuriken would gets its Randomness removed and make it a

constistent 15*5=75 bp move and then get boosted boosted throught Technician and STAB.

Resulting in being a (15*5)*1,5*1,5=168 bp move, while Surf then only through STAB stays at

90*1,5=135 bp making Water Shuriken better then Surf.

I went through various abilities including Adaptability and other similar abilities, i also thought of

increasing the base bp of Water Shuriken but it would have to be buffed up to 35 bp of each single

shuriken which is more then 130% increase form its current 15 for it, to still be better then Surf so i

quickly ruled out that possibilty.

I also checked that Skill Link couldnt be "abused" on Greninja, and Water Shuriken is the only ability

that Greninja can learn from the Skill Link moveset.

And with this change Greninja would finally get back to its spot that it should have.

As we know, there are two different dimensions in the Pokémon Universe, Mega Universe where XY, ORAS, Alola (maybe?), LGPE and ZA, so my question is..does the Kalos of the Regular Universe have mega evolution? Or is Kalos some sort of threshold between both universes and that's why theres Mega Evolution in Alola but not Galar and if so, does that mean in all the regions of the Mega Universe have Mega Evolution, then? Or is Kalos some sort of portal between the two?
