These are the ONLY pokemon that are uber

Jirachi, isn't uber due too it's 'limited movepool'

Celebi, isn't uber due too the fact that it has 7 weaknesses (4x to Bug,2x to Fire/Flying/Posion/Ice/Dark/Ghost)

Slaking isn't uber despite having the same base stat total as kyogre, due to its abillity Truant

Other legends aren't uber (Articuno/Zapdos/Moltres/Raikou/Suicune/Entei/Regice/Registeel/Regirock)
no matter how much you say they are, they aren't.
