Should every Pokemon have their own Signature move?

[steel dragons]

I don't think that it would be necessary for every Pokemon to have their own, unique signature move, as it would take too much effort (imagine how many different moves there would be).

There are some moves that are 'signature moves' yet they are dispersed to different Pokemon. For example, in Gen 3, Each of the starters had a signature move (Muddy Water, Leaf Blade, Blaze Kick) and those moves were actually somewhat popular, at least in the games. I would say that those moves are still signature moves, but that more Pokemon can learn them.

On a side note, in Gen 3, Sceptile has arguably the best Grass move in the game, Leaf Blade. Despite the low base power, I would say that Leaf Blade was really a great move. Frenzy Plant, the most powerful Grass move, had the bad Hyper Beam-like side effect; Solarbeam, the second most powerful Grass move, is unreliable because of the 'charging' turn; and Petal Dance, tied with Leaf Blade's power at 70, had the Outrage-like bad effect of locking you into Petal Dance for two turns, then confusing you. Thus, Leaf Blade is the most consistently power Grass move in Gen 3, and only the Sceptile family could learn it. Blaze Kick and Muddy Water were good for Blaziken and Swampert respectively, but there were other powerful, reasonably consistent alternatives to those moves, unlike Leaf Blade.

I completely disagree its unfair for ledgendarys to only have signiture moves.All pokemon should have a special move!

I think that pokemon shouldn't have their own signature move. Just like steel dragon said it will take to much effort and they'll start running out of ideas like how they did with pokemon designs.

Marowak has Bone Throw. Blaze Kick is a move for Hitmonlee also, therefore not only Blaziken. Not only legendary, there are some pokemon with them. Regardless the most important should have unique moves, for them only.

There should be less signature moves.
