Ability-wise, Gen 4 cover legends are the most cucked and worst:
Ho-Oh and Lugia: They were stuck with Pressure like most legends, but Gen 5 gave them Regenerator and Multiscale, making them to have niches thanks to their abilities.
Groudon, Kyogre, and Rayquaza: Groudon and Kyogre lost their niches of being automatic setters of Sun and Rain in Gen 5, and in Gen 6 their abilities were nerfed but they received new abilities that are improved weathers that prevent other weathers to be called until they are switched out. Rayquaza received Delta Stream, an ability that deletes its x4 weakness to Ice.
Reshiram and Zekrom: Their abilities are renamed Mold Breakers, and are useful due to being introduced in the same generation that Sturdy became Focus Sash made ability.
Black Kyurem and White Kyurem: same that Reshiram and Zekrom.
Xerneas and Zekrom: despite they have shitass offensive stats at 131, Fairy Aura and Dark Aura boosts their main STABs and made them to hit as hard as other cover legendaries while having their stats distribuited into bulk.
Solgaleo and Lunala: Don't have the best abilities but at least is not Pressure.
Meanwhile Dialga, Palkia and Giratina had Pressure (Giratina Origin had Levitate) and received Telepathy. As ORAS gave Groudon, Kyogre and Rayquaza new abilities and formes, do you think it will happen with Dialga, Palkia and Rayquaza?

Just wait for the Sinnoh remakes :^)

>Rayquaza
Shit man, it already got a Mega, what more do you want?

My bad, I want to say Giratina.

Dude, Shadow Shield is what makes Lunala retardely obnoxious to deal with.

Temporal Ruler: Abilities that need to charge up or rest only take 1 turn but deal 3/4 of damage
Spatial Ruler: Attacks will always hit even if the opponent uses moves that dodge e.g. protect, fly etc.
Antimatter Ruler: Not very effective attacks become super effective
Gen 3s only got them because that was a significant element in Megas. Z moves would be the focus of remakes in this Gen so they would only get powered up signature moves.
You don't need a good ability to be good though

I always imagined Dialga or Palkia to get an trick room set up ability in possible remakes like wheater or fields
